Abstract
Background In the US, yersinosis was understood to predominantly occur in winter and among Black or African American infants and Asian children. Increased use of culture-independent diagnostic tests (CIDTs) has led to marked increases in yersinosis diagnoses. Methods We describe differences in the epidemiology of yersiniosis diagnosed by CIDT versus culture in 10 US sites, and identify determinants of health associated with diagnostic method. Results Annual reported incidence increased from 0.3/100 000 in 2010 to 1.3/100 000 in 2021, particularly among adults ≥18 years, regardless of race and ethnicity, and during summer months. The proportion of CIDT-diagnosed infections increased from 3% in 2012 to 89% in 2021. An ill person's demographic characteristics and location of residence had a significant impact on their odds of being diagnosed by CIDT. Conclusions Improved detection due to increased CIDT use has altered our understanding of yersinosis epidemiology, however differential access to CIDTs may still affect our understanding of yersinosis.

Abstract
Low-income families are reported to have a limited knowledge of food safety and resources to follow food safety practices compared with the rest of the population. This paper evaluated a virtual food safety educational program targeting food handlers in low-income families. Trained native speakers of English and Spanish delivered course materials in both languages. A total of 60 individuals participated in the program, with 30 participants in each language group. Most were female, and most had fewer than three children. After the program, participants’ food safety knowledge and self-reported safe food practice behavior scores increased significantly from 5.32 to 7.43 (out of 8.00) and from 24.78 to 29.30 (out of 35.00), respectively. The theory of planned behavior (TPB) was used to understand individuals’ behavior change intention of food safety practices. All the TPB constructs’ scores, including attitudes toward the behavior, perceived behavioral control, subjective norms, and behavior change intentions, were improved significantly; however, only the subjective norms and perceived behavioral control were significantly correlated with the behavior change intentions. This virtual educational program improved low-income individuals’ food safety knowledge and changed their food safety attitudes and behaviors, giving a path to develop and evaluate more virtual food safety educational programs in the future.

Abstract
INTRODUCTION In the spring of 2014, there was an outbreak of Yersinia enterocolitica (YE) gastroenteritis in four Norwegian military camps-the largest outbreak ever reported in Norway. YE is usually transmitted via food, and the gastrointestinal disease caused by the bacterium is considered a public health problem in several countries. Common symptoms of YE gastroenteritis are abdominal pain, diarrhea, fever, nausea, and vomiting. Post-infectious complications can occur after YE gastroenteritis, the most common of which are erythema nodosum and reactive arthritis. Based on self-reported data, we describe the duration of illness, the duration of any absence from service, and the incidence of symptoms of post-infectious complications in two groups of servicepeople: one diagnosed with YE gastroenteritis and the other with an unspecified acute infectious gastroenteritis. MATERIALS AND METHODS The Norwegian Armed Forces Health Register (NAFHR) is a central health register that contains data from conscripts and from military and civilian personnel in the Norwegian Armed Forces. In this study, we identified all individuals with a diagnosis of YE gastroenteritis in the NAFHR in the period from January 1 to June 30, 2014 (n = 128) as well as all those with a diagnosis of an unspecified acute infectious gastroenteritis in the same period (n = 323) to participate as controls. In October 2018, a link to an internet-based questionnaire was distributed by e-mail to all identified individuals. The questionnaires collected data on the duration of illness, the duration of absence from service, and the incidence of symptoms of post-infectious complications. RESULTS Of all those who received the questionnaire, 72 (59%) were included in the YE group and 117 people (36%) were included in the control group. Half of those in the YE group were ill for more than 13 days, while almost all (90%) of those in the control group recovered after 1 week. There were no differences between the groups in the incidence of symptoms of post-infectious complications during the 6 weeks after recovery. There was a significantly larger proportion of officers than conscripts in the YE group who reported symptoms of post-infectious complications. None of the respondents reported symptoms of post-infectious complications in the 6 months after the termination of military service. CONCLUSION One strength of this study is that we were able to investigate a large outbreak of YE gastroenteritis in a group of individuals with good underlying health. Weaknesses are the low response rate, especially in the control group, and the fact that we sent out the questionnaire >4 years after the acute gastroenteritis occurred. YE gastroenteritis among personnel in the Norwegian Armed Forces was associated with a significantly longer duration of illness and a longer duration of absence from service than that resulting from an unspecified acute infectious gastroenteritis. However, YE gastroenteritis was not associated with more symptoms of post-infectious complications.

Abstract
An ongoing outbreak of multidrug-resistant Salmonella enterica serovar Anatum began in Taiwan in 2015. Pork and poultry were identified as vehicles for transmission. Contaminated meat contributed to the high rate of infections among children. Nearly identical Salmonella Anatum strains have been identified in the United Kingdom, the United States, and the Philippines.

Abstract
Pigs are considered the main reservoir of Yersinia enterocolitica, and hence, understanding the ecology of this foodborne pathogen at the farm level is crucial. We calculated Bayesian estimates for the ability of a commercial enzyme-linked immunosorbent assay (ELISA) diagnostic test kit to detect antibodies against pathogenic Yersinia in pigs. The sensitivity and specificity of the test were 75.4% and 98.1%, respectively. We also studied the dynamics of Y. enterocolitica infection in 3 farrow-to-finish pig farms by following the same 30 pens of pigs through their lifetime from farrowing unit to slaughterhouse. Each farm was sampled 4 times, and 864 fecal and 730 serum samples were collected altogether. Pathogenic Y. enterocolitica 4/O:3 was isolated from 31.6% of the fecal samples by culturing, and Yersinia antibodies were detected in 38.2% of the serum samples with the commercial ELISA test. The pathogen was not isolated from farrowing units or all-in/all-out weaning units. However, in the weaning and fattening units using continuous management systems, the pathogen was isolated from every pen at some point of the study. After the pigs were transported into slaughterhouse, 150 tonsils were collected and 96.7% were positive by culturing. Among the strains isolated from feces and tonsils, 56 different genotypes of pathogenic Y. enterocolitica 4/O:3 were found by multilocus variable-number tandem-repeat analysis (MLVA). Finally, we collected tonsils of 266 sows from 115 farrowing farms, and Y. enterocolitica 4/O:3 was detected in 6.0% of the samples by the culture method, whereas 77.1% of the tonsils were serologically positive; the estimate for true seroprevalence was 95.8%. In conclusion, sows may not be the main source of Y. enterocolitica for piglets, although sows may still play a role in maintaining Y. enterocolitica in pig farms. Instead, pigs appear to get this foodborne pathogen mainly during the fattening period, especially if continuous management is applied.

Abstract
Descriptive epidemiology of Yersinia enterocolitica infection in an area of Castellón (Spain) between 2006 and 2013 from Yersinia enterocolitica strains isolated in the area and confirmed by the Spanish national reference laboratory. There were a total of 144 cases. The estimated incidence was 9.7 cases per 105 person-year. The age group most affected was 0-4 years (rate 110.3 per 105 p-y), with a maximum in infants aged 6 to 11 months of age (190.4 per 105 p-y). The average duration of the disease was 15.5 days. 7% of the patients were hospitalised. Only 2 outbreaks of a family nature related to the consumption of pork were detected. The temporal evolution reflects higher incidence during the winter season (January). The most common exposure factor among the cases was the consumption of dried pork sausage (50% of the cases interviewed). The 58 typed strains were all of the biotype 4, serotype O:3, except one O:9. We distinguished 21 pulsotypes grouped in 8 clusters with a similarity of 97%. Over a number of years, a substitution of some pulsotypes for others was observed. Yersiniosis has a high incidence in our area, with a clear seasonality of winter predominance. It affects very young children, in particular. The strains are of the same serotype, but the variety of pulsotypes changed over time. As an exposure factor for further analytical studies, the consumption of some pork products is proposed, without ruling out other factors.

Abstract
Yersinia enterocolitica is thought to not significantly contribute to diarrheal disease in China, but evidence substantiating this claim is limited. We determined the prevalence of Y. enterocolitica infection and strain types present among children <5 years of age with diarrhea in China. The overall prevalence of pathogenic isolates was 0.59%. Prevalence of pathogenic bioserotype 3/O:3 varied geographically. In this population, the presence of fecal leukocytes was a characteristic of Y. enterocolitica infection and should be used as an indication for microbiological diagnostic testing, rather than for the diagnosis of bacillary dysentery. In contrast with Y. enterocolitica isolates from adults, which were primarily biotype 1A, isolates from children were primarily bioserotype 3/O:3. Most pathogenic isolates from children shared pulsed-field gel electrophoresis patterns with isolates from pigs and dogs, suggesting a possible link between isolates from animals and infections in children. Our findings underscore the need for improved diagnostics for this underestimated pathogen.

Abstract
Pathogens associated with food production (livestock) animals come in many forms causing a multitude of disease for humans. For the purpose of this review, these infectious agents can be divided into three broad categories: those that are associated with bacterial disease, those that are associated with viruses, and those that are parasitic in nature. The goal of this chapter is to provide the reader with an overview of the most common pathogens that cause disease in humans through exposure via the food chain and the consequence of this exposure as well as risk and detection methods. We have also included a collection of unusual pathogens that although rare have still caused disease, and their recognition is warranted in light of emerging and reemerging diseases. These provide the reader an understanding of where the next big outbreak could occur. The influence of the global economy, the movement of people, and food makes understanding production animal-associated disease paramount to being able to address new diseases as they arise.

Abstract
Yersinia enterocolitica is a gram-negative cocobacillus causing a range of illness from self-limited enteritis to invasive disease, including septicemia. It is a particularly virulent pathogen in patients with underlying hemoglobinopathies who are predisposed to iron overload. A substantial risk factor for disease in children and infants is exposure to the household preparation of chitterlings. Early identification of these patients is critical in the pediatric intensive care unit as this cause of septicemia can be missed with the potential for significant morbidity. We report an interesting case of Yersinia septicemia in a patient with iron overload disease from chitterling ingestion managed in the pediatric intensive care unit.

Abstract
Salmonella, Shigella, and Yersinia cause a well-characterized spectrum of disease in humans, ranging from asymptomatic carriage to hemorrhagic colitis and fatal typhoidal fever. These pathogens are responsible for millions of cases of food-borne illness in the United States each year, with substantial costs measured in hospitalizations and lost productivity. In the developing world, illness caused by these pathogens is not only more prevalent but also associated with a greater case-fatality rate. Classic methods for identification rely on selective media and serology, but newer methods based on mass spectrometry and polymerase chain reaction show great promise for routine clinical testing.

Abstract
Yersinia enterocolitica is a gastrointestinal pathogen which causes yersiniosis, an illness characterized by diarrhea, ileitis, and mesenteric lymphadenitis. Y. enterocolitica is transmitted via the feco-oral route by the consumption of contaminated food or water. Several phenotypic and genotypic methods have been developed to reliably detect Y. enterocolitica in food. However, the source of infection of many recently reported foodborne outbreaks remains obscure. The detection of this pathogen in food is a challenging task, since it shares similarities with other enteric bacteria. The presence of other microorganisms in the food samples makes it even more difficult to identify this slow-growing pathogen. Therefore, the present-day emphasis is on the development of sensitive, easily automated methods suitable for in-situ detection, allowing quick and cost-effective characterization of food samples. This review summarizes and compares the currently available cultural, immunological, and molecular methods, particularly in relation to their specific merits or demerits when implemented for the detection of Y. enterocolitica in food.

Abstract
In this study, an oral minipig infection model was established to investigate the pathogenicity of Yersinia enterocolitica bioserotype 4/O:3. O:3 strains are highly prevalent in pigs, which are usually symptomless carriers, and they represent the most common cause of human yersiniosis. To assess the pathogenic potential of the O:3 serotype, we compared the colonization properties of Y. enterocolitica O:3 with O:8, a highly mouse-virulent Y. enterocolitica serotype, in minipigs and mice. We found that O:3 is a significantly better colonizer of swine than is O:8. Coinfection studies with O:3 mutant strains demonstrated that small variations within the O:3 genome leading to higher amounts of the primary adhesion factor invasin (InvA) improved colonization and/or survival of this serotype in swine but had only a minor effect on the colonization of mice. We further demonstrated that a deletion of the invA gene abolished long-term colonization in the pigs. Our results indicate a primary role for invasin in naturally occurring Y. enterocolitica O:3 infections in pigs and reveal a higher adaptation of O:3 than O:8 strains to their natural pig reservoir host.

Abstract
Colicin FY is a plasmid encoded toxin that recognizes a yersinia-specific outer membrane protein (YiuR) as a receptor molecule. We have previously shown that the activity spectrum of colicin FY comprises strains of the genus Yersinia. In this study, we analyzed the activity of colicin FY against 110 Yersinia enterocolitica isolates differing in geographical origin and source. All isolates were characterized through analysis of 16S rRNA genes, serotyping, biotyping, restriction profiling of genomic DNA, detection of virulence markers and susceptibility to antibiotics. This confirmed the broad variability of the collection, in which all 110 Y. enterocolitica isolates, representing 77 various strains, were inhibited by colicin FY. Although isolates showed variable levels of susceptibility to colicin FY, it was not associated with any strain characteristic. The universal susceptibility of Y. enterocolitica strains to colicin FY together with the absence of activity towards strains outside the Yersinia genus suggests potential therapeutic applications for colicin FY.

Abstract
SUMMARYIn July 2011, a cluster ofYersinia enterocoliticainfections was detected in southwestern Pennsylvania, USA. We investigated the outbreak's source and scope in order to prevent further transmission. Twenty-two persons were diagnosed with yersiniosis; 16 of whom reported consuming pasteurized dairy products from dairy A. Pasteurized milk and food samples were collected from this dairy.Y. enterocoliticawas isolated from two products. Isolates from both food samples and available clinical isolates from nine dairy A consumers were indistinguishable by pulsed-field gel electrophoresis. Environmental and microbiological investigations were performed at dairy A and pasteurization deficiencies were noted. Because consumption of pasteurized milk is common and outbreaks have the potential to become large, public health interventions such as consumer advisories or closure of the dairy must be implemented quickly to prevent additional cases if epidemiological or laboratory evidence implicates pasteurized milk as the outbreak source.

Abstract
Sporadic and epidemiologically linked Yersinia enterocolitica strains (n = 379) isolated from fecal samples from human patients, tonsil or fecal samples from pigs collected at slaughterhouses, and pork samples collected at meat stores were genotyped using multiple-locus variable-number tandem-repeat analysis (MLVA) with six loci, i.e., V2A, V4, V5, V6, V7, and V9. In total, 312 different MLVA types were found. Similar types were detected (i) in fecal samples collected from human patients over 2 to 3 consecutive years, (ii) in samples from humans and pigs, and (iii) in samples from pigs that originated from the same farms. Among porcine strains, we found farm-specific MLVA profiles. Variations in the numbers of tandem repeats from one to four for variable-number tandem-repeat (VNTR) loci V2A, V5, V6, and V7 were observed within a farm. MLVA was applicable for serotypes O:3, O:5,27, and O:9 and appeared to be a highly discriminating tool for distinguishing sporadic and outbreak-related strains. With long-term use, interpretation of the results became more challenging due to variations in more-discriminating loci, as was observed for strains originating from pig farms. Additionally, we encountered unexpectedly short V2A VNTR fragments and sequenced them. According to the sequencing results, updated guidelines for interpreting V2A VNTR results were prepared.

Abstract
BACKGROUND Yersinia enterocolitica causes an estimated 116,716 illnesses annually in the United States. Black children have historically had the highest rates of infection, with incidence peaking in the winter. METHODS The Foodborne Diseases Active Surveillance Network (FoodNet) conducts active surveillance for laboratory-confirmed Y. enterocolitica infections, defined as the isolation of Y. enterocolitica or unspeciated Yersinia from a human clinical specimen. We calculated the average annual crude incidence rate per 100,000 persons from 1996 through 2009 and described rates by age, race, and geographic site. To account for changes in the FoodNet catchment area, we used a negative binomial model to estimate statistical changes in incidence using the average annual incidence in 1996-1998 as the baseline. RESULTS From 1996 through 2009, 2085 Y. enterocolitica infections were reported to FoodNet. The average annual crude incidence was 0.5 per 100,000 persons and was highest in blacks (0.9 per 100,000 persons). Over time, the rate in blacks declined from 3.9 to 0.4 per 100,000 persons. Declines among other racial groups were not as pronounced. The largest decline occurred in black children <5 years old (from 41.5 per 100,000 persons in 1996 to 3.5 per 100,000 persons in 2009). From 2007 through 2009, the highest rate of infection was in Asian children (5.1 per 100,000 persons). Compared with 1996-1998, the incidence in 2009 was 66% (95% confidence interval, 51%-77%) lower among children <5 years old. CONCLUSIONS Y. enterocolitica infections in FoodNet sites have significantly declined since 1996. These declines were greatest in young black children, the group that initially had the highest incidence, possibly as the result of educational efforts in Georgia.

Abstract
Epidemic-assistance investigations (Epi-Aids) in response to outbreaks of foodborne and other enteric pathogens have identified novel pathogens, clinical syndromes, and sequelae; described new reservoirs and vehicles of transmission; evaluated existing prevention strategies; and identified deficiencies in the food safety systems on local, national, and international levels. Since the first Epi-Aid was issued in 1946, approximately 23% (1,023 of 4,484 for which investigations were initiated) of all Epi-Aids have been related to foodborne or other enteric diseases. Epi-Aid results have yielded valuable insights into the epidemiology of these pathogens and have molded prevention strategies for detecting, responding to, and preventing future outbreaks. New challenges, brought about in part by centralization and globalization of the food supply, will continue to emerge. The need for Epi-Aids of such outbreaks undoubtedly will persist as an integral part of future public health response efforts, prevention strategies, and training programs.

Abstract
BACKGROUND The bacteriostatic activity of the transferrin family has been known since the early 1960's. The possession of high affinity iron(III)-binding sites and the existence of a specific membrane-bound receptor, have led to the present understanding of serum transferrin acting as the major iron transporter between cells in vertebrate systems. Iron chelators can interact with transferrin, either by directly donating iron or by removing iron from the protein; both interactions have relevance for haematology. SCOPE OF REVIEW Urea polyacrylamide gels and HPLC methods have been developed for the resolution and quantification of the four major forms of transferrin, diferric-transferrin, C-mono Fe-transferrin, N-mono Fe-transferrin and apo transferrin. MAJOR CONCLUSIONS Negatively charged ligands with pFe values >20 remove iron from transferrin, preferably from the N-lobe iron-binding site. Some siderophores are capable of removing iron from transferrin. 3-Hydroxypyridin-4-ones, lacking a negative charge are able to remove iron from transferrin with a strong preference for the C- lobe iron-binding site. The donation of iron to apo transferrin by hydroxypyridinone iron(III) complexes has relevance to the treatment of clinical anaemias, because the hydroxypyridinones can also mobilize iron from the reticuloendothelial system and so facilitate the redistribution of iron from macrophages to reticulocytes. GENERAL SIGNIFICANCE Hydroxypyridinones have excellent potential for facilitating the redistribution of iron and this has relevance to the treatment of many disease types, including neurodegeneration and clinical anaemias. This article is part of a Special Issue entitled Transferrins: Molecular mechanisms of iron transport and disorders.

Abstract
Yersinia enterocolitica are ubiquitous, being isolated frequently from soil, water, animals, and a variety of foods. They comprise a biochemically heterogeneous group that can survive and grow at refrigeration temperatures. The ability to propagate at refrigeration temperatures is of considerable significance in food hygiene. Virulent strains of Yersinia invade mammalian cells such as HeLa cells in tissue culture. Two chromosomal genes, inv and ail, were identified for cell invasion of mammalian. The pathogen can cause diarrhoea, appendicitis and post-infection arthritis may occur in a small proportion of cases. The most common transmission route of pathogenic Y. enterocolitica is thought to be fecal-oral via contaminated food. Direct person-to-person contact is rare. Occasionally, pathogenic Y. enterocolitica has been detected in vegetables and environmental water; thus, vegetables and untreated water are also potential sources of human yersiniosis. However, the isolation rates of pathogenic Y. enterocolitica have been low, which may be due to the limited sensitivity of the detection methods. To identify other possible transmission vehicles, different food items should be studied more extensively. Many factors related to the epidemiology of Y. enterocolitica, such as sources, transmission routes, and predominating genotypes remain obscure because of the low sensitivity of detection methods.

Abstract
Although Yersinia enterocolitica is usually transmitted through contaminated food and untreated water, occasional transmission such as human-to-human, animal-to-human and blood transfusion associated transmission have also identified in human disease. Of the six Y. enterocolitica biotypes, the virulence of the pathogenic biotypes, namely, 1B and 2-5 is attributed to the presence of a highly conserved 70-kb virulence plasmid, termed pYV/pCD and certain chromosomal genes. Some biotype 1A strains, despite lacking virulence plasmid (pYV) and traditional chromosomal virulence genes, are isolated frequently from humans with gastrointestinal diseases similar to that produced by isolates belonging known pathogenic biotypes. Y. enterocolitica pathogenic biotypes have evolved two major properties: the ability to penetrate the intestinal wall, which is thought to be controlled by plasmid genes, and the production of heat-stable enterotoxin, which is controlled by chromosomal genes.

Abstract
Many enteric pathogens are equipped with multiple cell adhesion factors which are important for host tissue colonization and virulence. Y. enterocolitica, a common food-borne pathogen with invasive properties, uses the surface proteins invasin and YadA for host cell binding and entry. In this study, we demonstrate unique cell adhesion and invasion properties of Y. enterocolitica serotype O:3 strains, the most frequent cause of human yersiniosis, and show that these differences are mainly attributable to variations affecting the function and expression of invasin in response to temperature. In contrast to other enteric Yersinia strains, invasin production in O:3 strains is constitutive and largely enhanced compared to other Y. enterocolitica serotypes, in which invA expression is temperature-regulated and significantly reduced at 37°C. Increase of invasin levels is caused by (i) an IS1667 insertion into the invA promoter region, which includes an additional promoter and RovA and H-NS binding sites, and (ii) a P98S substitution in the invA activator protein RovA rendering the regulator less susceptible to proteolysis. Both variations were shown to influence bacterial colonization in a murine infection model. Furthermore, we found that co-expression of YadA and down-regulation of the O-antigen at 37°C is required to allow efficient internalization by the InvA protein. We conclude that even small variations in the expression of virulence factors can provoke a major difference in the virulence properties of closely related pathogens which may confer better survival or a higher pathogenic potential in a certain host or host environment.

Abstract
Pigs are the major animal reservoir for Yersinia enterocolitica strains, which are potentially pathogenic for humans. The goals of this study were (i) to estimate the individual animal and on-farm prevalences of Y. enterocolitica in hogs based on tonsil samples collected during National Animal Health Monitoring System Swine 2002 study and (ii) to use these data with data previously published for fecal samples to determine on-farm risk factors for Y. enterocolitica. Tonsil swabs (1,218) and fecal samples (2,847) were collected on 124 farms located in the top 17 pork-producing states. Ten percent of tonsils (122 of 1,218 samples) were positive in irgasan-tiracillin-chlorate (ITC) enrichment broth by real-time PCR, but only 5.6% of samples (68 of 1,218) were positive after subculture on the more selective cefsulodin-irgasan-novobiocin (CIN) agar. For tonsils, the on-farm prevalence based on real-time PCR detection of the ail gene in ITC enrichment broth cultures was 32% (32 of 100 premises sampled); the prevalence based on subculture in CIN agar was 19.6% (20 of 102 premises). Results of bacteriological isolation and real-time PCR analysis of tonsils and feces were combined to estimate prevalence (individual animal and farm), which was subsequently correlated with 40 farm management practices. Four factors and their accompanying odds ratios (ORs) were identified in the final regression model: location in a central state (OR = 0.3), vaccination for Escherichia coli (OR = 3.0), percentage of deaths due to scours (OR = 3.5), and presence of meat or bone meal in grower-finisher diet (OR = 4.1).

Abstract
Pig herds that provide pork free from zoonotic agents may be possible. Pork products are a substantial source of human yersiniosis, a foodborne disease caused by Yersinia enterocolitica. Thus, the ability to eliminate this agent from pig herds would be an important step in producing human pathogen–free pork. Pig herds free from Y. enterocolitica O:3/biovar 4 have been established and maintained. According to serologic and cultural testing results, 15 of 16 specific pathogen–free herds were free from Y. enterocolitica O:3/biovar 4; this closed breeding pyramid has remained free from this organism since 1996. Pig herds free from human pathogenic Y. enterocolitica suggest that human pathogen–free herds could be attained to provide pork free from zoonotic agents.

Abstract
In this article, the third in a series of several reviewing the role of food workers in 816 foodborne outbreaks, factors contributing to outbreaks and descriptions of different categories of worker involvement are discussed. All the outbreaks had worker involvement of some kind, and the majority of food workers were infected. The most frequently reported factor associated with the involvement of the infected worker was bare hand contact with the food followed by failure to properly wash hands, inadequate cleaning of processing or preparation equipment or utensils, cross-contamination of ready-to-eat foods by contaminated raw ingredients, and (for bacterial pathogens) temperature abuse. Many of the workers were asymptomatic shedders or had infected family members and/or used improper hygienic practices. Outbreaks were sorted into categories based on how many workers were implicated, the origin of the infective agent (outbreak setting or off site), the degree of certainty that the worker(s) were the cause or were victims, whether or not the workers denied illness, the ability of the agent to grow in the food, whether only the workers and not the patrons were ill, and whether patrons were more responsible for their illnesses than were the workers. The most frequent scenarios were (i) a single worker causing an outbreak by directly infecting patrons; (ii) an infected worker fecally contaminating foods that were then temperature abused, leading to an outbreak; and (iii) multiple workers linked to an outbreak but with no clear initiating source. Multi-ingredient foods with limited descriptions were most frequently implicated and usually were served in restaurants or hotels, at schools, and at catered events. Identified contaminated ready-to-eat foods included produce, baked goods, beverages, and meat and poultry items. In some situations, it was not clear whether some of the workers were the cause or the victims of the outbreak. However, in other situations there may have been an underestimation of the role of the worker. For instance, workers sometimes denied infection or illness for a variety of reasons, but subsequent investigation provided evidence of infection.

Abstract
The distribution of Yersinia strains in animal reservoirs was examined in 835 food animals (pigs, chickens, sheep, cows) from different Greek departments (Attica, Fthiotida, Viotia and Evia) over a one year period. The isolated strains were characterized with respect to the presence of chromosomal (yst) and plasmid-encoded virulence determinants (virF, yadA) and their antimicrobial susceptibility was tested. In total, Yersiniaspp. were obtained from 9.94% of the 835 food animals at slaughter that were sampled in this study. There was no statistically significant seasonal distribution, nor was any significant departmental distribution observed. From the 83 isolated Yersinia strains, 76 (91,57%) belonged to Y. enterocolitica (58 were of serotype O:3/biotype 4 and 18 strains were non O:3, non O:9), 3 belonged to Y. pseudotuberculosis, 2 to Y. kristensenii and 2 to Y. intermedia. Y. enterocolitica O:3/4 was mainly isolated from the pigs, while Y. enterocolitica non O:3, non O:9 was from the chickens. The strains were grouped into 5 genotypes, with respect to the presence or absence of the virulence genes. A significant predominance of genotype V, the one carrying all the three virulence genes, was observed in the strains isolated from the pigs. Complete susceptibility to most of the 3rd and to the 4th generation cephalosporins and to ciprofloxacin, was observed among the isolates. Remarkable was the association between the presence of each virulence gene separately and resistance to some antimicrobials, a matter of further investigation.

Abstract
Food workers in many settings have been responsible for foodborne disease outbreaks for decades, and there is no indication that this is diminishing. The Committee on Control of Foodborne Illnesses of the International Association for Food Protection was tasked with collecting and evaluating any data on worker-associated outbreaks. A total of 816 reports with 80,682 cases were collected from events that occurred from 1927 until the first quarter of 2006. Most of the outbreaks reviewed were from the United States, Canada, Europe, and Australia, with relatively few from other parts of the world, indicating the skewed set of data because of availability in the literature or personal contact. Outbreaks were caused by 14 agents: norovirus or probable norovirus (338), Salmonella enterica (151), hepatitis A virus (84), Staphylococcus aureus (53), Shigella spp. (33), Streptococcus Lancefield groups A and G (17), and parasites Cyclospora, Giardia, and Cryptosporidium (23). Streptococcal, staphylococcal, and typhoid outbreaks seem to be diminishing over time; hepatitis A virus remains static, whereas norovirus and maybe nontyphoidal Salmonella are increasing. Multiple foods and multi-ingredient foods were identified most frequently with outbreaks, perhaps because of more frequent hand contact during preparation and serving.

Abstract
A national study was conducted for the isolation of pathogenic Yersinia enterocolitica in pig feces in the United States as part of the National Animal Health Monitoring System's Swine 2000 study. Fecal samples collected from swine operations from September 2000 to March 2001 from 77 production sites in 15 of the top 17 swine-producing states were tested for the presence of pathogenic Y. enterocolitica. After enrichment of swine fecal samples in irgasan-ticarcillin-potassium chlorate broth, the enriched cultures were plated on cefsulodin-irgasan-novobiocin agar for isolation of presumptive Y. enterocolitica. The isolates were confirmed as pathogenic Y. enterocolitica by the fluorogenic 5' nuclease PCR assay targeting the chromosomal attachment invasion ail gene. Of 2793 fecal samples tested, 106 (3.80%) ail-positive strains of Y. enterocolitica were isolated. These 106 ail-positive isolates originated from 7 of the 15 participating states. The predominant serotype O:3 (n = 79 of 106) was distributed in five states (n = 5 of 7). Serotype O:5 (n = 27 of 106) was also found in five states (n = 5 of 7). All isolates contained the virulence plasmid and expressed virulence-associated phenotypic characteristics. These results indicate that swine in the United Stares harbor Y. enterocolitica that can potentially cause human illness.

Abstract
The influence of freeze stress at -20 degrees C on the enrichment, isolation, detection, presence of virulence plasmid, and expression of virulence of plasmid-bearing Yersinia enterocolitica (YEP+) inoculated on pork chop medallions was assessed. Pork chop medallions (10 cm2) artificially contaminated with 10, 1, and 0.5 CFU/cm2 of YEP+ strains (serotype O:3) were placed in sterile petri dishes at -20 degrees C for 24 h. The medallions were swabbed when frozen, after thawing at room temperature for 1.5 h and after thawing at 4 degrees C for 18 h. Swabs were enriched and YEP+ were detected and isolated using the Congo red-binding and low-calcium-response assays. The YEP+ were isolated under all conditions on pork chop medallions inoculated with 10 CFU/cm2 and at a level of 1 CFU/cm2 when thawed at room temperature and at 4 degrees C but not from frozen pork chop medallions. The YEP+ were not isolated from pork chop medallions inoculated with 0.5 CFU/cm2 and then frozen, whereas YEP+ were recovered when inoculated at this level from pork chop medallions not subjected to freezing. Virulence of the strains isolated from frozen pork chop medallions was confirmed by PCR and the expression of plasmid-associated phenotypes. These results indicate that YEP+ subjected to freezing on pork are potentially capable of causing foodborne illness and that freezing is not a substitute for safe handling and proper cooking of pork.

Abstract
BACKGROUND Previous studies of bacterial enteric infections have suggested a disproportionate disease burden for children younger than 5 years of age. OBJECTIVES This study describes population-based incidence of culture-confirmed infections with 6 bacterial enteric pathogens in children younger than 5 years of age in the Foodborne Diseases Active Surveillance Network (FoodNet), 1996-1998. METHODS Cases were ascertained through active laboratory-based surveillance in Minnesota, Oregon and selected counties in California, Connecticut, Georgia, Maryland and New York. RESULTS Twenty-one percent (5218 of 24,358) of infections were in children younger than 5 years of age, but this age group made up only 7% of the total person-years of observation. Among those younger than 5 years of age, the incidence (cases per 100,000 person-years) for each pathogen was: Salmonella, 55.3; Campylobacter, 43.4; Shigella, 32.7; E. coli O157, 10.3; Yersinia enterocolitica, 7.1; Listeria monocytogenes, 0.7. Incidence varied widely among the 7 FoodNet sites. CONCLUSIONS This study confirmed a disproportionate disease burden in young children. Investigation of risk factors specific to this age group and review and enhancement of current prevention and control strategies for children younger than 5 years of age may reduce illness.
