Flores Y, Chaves A, Suzán G. Prediction of edapho-climatic parameters in the incidence of Campylobacter spp. in northwestern Mexico. PLOS GLOBAL PUBLIC HEALTH 2024; 4:e0002812.

Abstract
Campylobacter spp. is one of the main causes of enteric zoonotic infections worldwide. In Mexico, although a commonly detected pathogen in both children and adults, there is limited surveillance and few studies. The northern part of Mexico stands out for an unnoticed outbreak of Campylobacter jejuni due to contaminated drinking water, which caused an abrupt increase in Guillain-Barré syndrome in the local population. Although it is suggested that its distribution in nature is related to edaphic and climatic factors, this relationship is scarcely known. To understand abiotic factors driving the occurrence and prevalence of Campylobacter spp. in three municipalities from three states in northwestern Mexico (Chihuahua, Sonora, and Baja California), we used the kriging interpolation method of unsampled areas and the correspondence analysis of 23 environmental variables. Of the three municipalities evaluated, Janos in Chihuahua (CHIH), has the highest number of geographic areas classified as high and medium incidence, followed by Santa Cruz, Sonora (SON) and Mexicali, Baja California (BC). Mexicali (BC) edaphic variables limit the potential incidence of the bacterium, mainly due to the lack of soil moisture and its difficulty of surviving on dry surfaces, related to electrical conductivity and salinity. Janos (CHIH) presents limitations in terms of soil water availability, although its presence is more heterogeneous (2 to 8 months). Santa Cruz (SON) has the highest soil water availability (4 to 5 months), and presents pH, texture and low percentage of salinity conditions for the potential incidence of Campylobacter spp. Mexicali (BC) reports a temperature in the warmest month of up to 43°C, which could influence the presence of thermophilic species. The annual precipitation is another limiting factor for the potential incidence of Campylobacter spp. since it does not exceed 509.5 mm, contributing to Janos (CHIH) as the municipality with the highest potential incidence of this bacterium.

Assessment of bacteriological quality and safety of raw meat at slaughterhouse and butchers' shop (retail outlets) in Assosa Town, Beneshangul Gumuz Regional State, Western Ethiopia. BMC Microbiol 2023; 23:403. [PMID: 38114898 PMCID: PMC10731869 DOI: 10.1186/s12866-023-03106-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2023] [Accepted: 11/03/2023] [Indexed: 12/21/2023] Open
Abstract
Contaminated meat has been implicated in many cases of foodborne illness and poses serious challenges in developing countries. This study aimed to assess the quality and safety of raw beef meat in Assosa Town. The finding showed that the mean of Aerobic mesophilic bacteria (AMB) and S. aureus at retail outlets was 5.04 log10cfu/g and 3.84 log10cfu/g; 4.03 log10cfu/g and 3.5 log10cfu/g at slaughterhouse, respectively. The microbial load range of AMB at the butcher shop was 2.49-5.16 log10 cfu/g, while at the abattoir it was 2.75-7.52 log10 cfu/g out of 70 raw beef meat analyzed samples. Similar to this, the butcher shop and abattoir had S. aureus microbiological load ranges of 2.74 - 4.84 log10 cfu/g and 2.71-4.72 log10 cfu/g, respectively. In contrast, 25.7% and 34.3% of the samples in the abattoir and retail shop, respectively, were contaminated with Salmonella sp. For S. aureus, just 38.71% and 17.14%, respectively, of the samples at the retail and butcher shops were satisfactory. AMB found that 80% of the examined samples from butcher shops and 57.7% from abattoirs were satisfactory. Due to poor handling and environmental hygiene procedures by Assosa Town butchers, 77.1% of the meat contact surface and 82.9% of the carcass were exposed to flies. On the other hand, only 5.7%, 28.6%, and 22.9% of the butchers kept the carcass in the refrigerator, and wore gowns and hairnets, respectively. In slaughterhouses, the majority of respondents (87.5%) concur that there were certain challenges in achieving slaughtering in the working environment.

Abstract
BACKGROUND Zoonotic food-borne pathogens such as Salmonella spp., which can be hosted by some raw foods, play a crucial role in ranking the public health of a country OBJECTIVES: The present study was conducted to assess the frequency, antibiotic resistance pattern and index of multiple antibiotic resistance (MAR) of Salmonella spp. in chicken meat METHODS: A cross-sectional survey was conducted from October 2017 to March 2018. One-hundred and fifty chicken meat samples were collected from meat stores in Zahedan, southeast of Iran and screened for contamination with Salmonella spp. using the polymerase chain reaction assay targeting the inv-A gene. Antimicrobial susceptibility testing was performed against 11 commonly prescribed antimicrobial agents in the veterinary treatment to calculate the MAR index RESULTS: The contamination rate was 2.7% (4/150). The antimicrobial resistance rate was 100% (n = 4) against penicillin, tylosin, tetracycline, erythromycin and tiamulin, 50% (n = 2) against trimethoprim/sulfamethoxazole, difloxacin and lincomycin/spectinomycin and 25% (n = 1) against flumequine and florfenicol. All isolates were sensitive to fosfomycin. Interestingly, all isolates (n = 4) exhibited different MAR patterns. Furthermore, the MAR index ranged from 0.45 to 0.81 CONCLUSIONS: In addition to the MAR index, which indicated that the isolate originated from a source where antibiotics were used to a great degree and/or in large amounts, the results showed that the chicken meat hosted resistant strains of Salmonella spp. in the study area. Overall, the findings indicated an important public health problem. To reduce this alarming signal, the poultry industry should implement control measures in the study area.

Abstract
Street food stands (SFS) are an understudied element of the food environment. Previous SFS studies have not used a rigorous approach to document the availability, density, and distribution of SFS across neighborhood income levels and points of access in Mexico City. A random sample (n = 761) of street segments representing 20 low-, middle-, and high-income neighborhoods were assessed using geographic information system (GIS) and ground-truthing methods. All three income levels contained SFS. However, SFS availability and density were higher in middle-income neighborhoods. The distribution of SFS showed that SFS were most often found near homes, transportation centers, and worksites. SFS availability near schools may have been limited by local school policies. Additional studies are needed to further document relationships between SFS availability, density, and distribution, and current structures and processes.

Abstract
Multiplex PCR (m-PCR) has the potential for more rapid detection of pathogens compared to simple PCR through the simultaneous amplification of multiple gene targets using several sets of specific primers. Here, we developed an m-PCR assay which combined dry reagent mixtures for ready-to-use simultaneous detection of Salmonella spp., Bacillus cereus, and Staphylococcus aureus. The assay did not show cross-reactivity with several common bacterial pathogens and the detection limit was 103 CFU/mL for mixed genomic DNA in pure culture. Lyophilized m-PCR reagents are stable for 2 months stored at 4 °C and for 1 month stored at 25 °C. Detection sensitivities of both dry and fresh mixes were able to simultaneously detect 10 CFU/mL of each pathogen in artificially inoculated samples after enrichment for 6 and 12 h. Results demonstrated that this method is both sensitive and specific and can be used for rapid detection and differentiation of foodborne diseases.

Abstract
The rapid detection of pathogens in food is becoming increasingly critical for ensuring the safety of consumers, since the majority of food-borne illnesses and deaths are caused by pathogenic bacteria. Hence, rapid, sensitive, inexpensive and convenient approaches to detect food-borne pathogenic bacteria is essential in controlling food safety. In this study, a multiplex PCR assay for the rapid and simultaneous detection of Escherichia coli O157:H7, Salmonella spp. and Listeria monocytogenes was established. The invA, stx and hlyA genes specifically amplified DNA fragments of 284, 404 and 510 bp from Salmonella spp., L. monocytogenes and E. coli O157:H7, respectively. The 16S rRNA gene was targeted as an internal control gene in the presence of bacterial DNA. The specificity and sensitivity of the multiplex PCR were performed by testing different strains. The multiplex PCR assay was able to specifically simultaneously detect ten colony-forming unit/mL of each pathogen in artificially inoculated samples after enrichment for 12 h. The whole process took less than 24 h to complete, indicating that the assay is suitable for reliable and rapid identification of these three food-borne pathogens, which could be suitable in microbial epidemiology investigation.
