Dogan OB, Aditya A, Ortuzar J, Clarke J, Wang B. A systematic review and meta-analysis of the efficacy of processing stages and interventions for controlling Campylobacter contamination during broiler chicken processing. Compr Rev Food Sci Food Saf 2021; 21:227-271. [PMID: 34730272 DOI: 10.1111/1541-4337.12860] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2021] [Revised: 09/16/2021] [Accepted: 09/17/2021] [Indexed: 12/13/2022]
Abstract
Systematic review and meta-analysis were conducted to quantify the effects of processing stages and interventions on the prevalence and concentration of Campylobacter on broiler carcasses. To comprehensively capture relevant evidence, six databases were searched using the keywords "Campylobacter" and "broiler chicken." The literature search yielded 10,450 unique citations, and after applying predetermined inclusion and exclusion criteria, 72 and 53 relevant citations were included in meta-analyses for processing stages and interventions, respectively. As the two primary outcomes, log reduction and prevalence changes were estimated for each stage or intervention using a random-effects meta-analysis approach whenever possible. The outcome-level quality assessment was conducted following the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The analysis revealed that scalding and chilling majorly reduces the prevalence and concentration of Campylobacter. Immersion chilling reduces the concentration regardless of chemical additives, but its effect on prevalence is not conclusive. The effects of carcass washing applications remain uncertain due to the inconsistency and imprecision of both outcomes. Defeathering and evisceration were identified as stages that can increase both prevalence and concentration. Both chemical and physical processing interventions provide limited efficacy in concentration and prevalence reduction. Major limitations of the review were inconsistency and imprecision at the outcome level and reporting issues and data gaps at the study level. The results are expected to inform quantitative microbial risk assessment model development and support evidence-based decision-making.

Abstract
1. The following study provides the first data on the detection and types of Listeria monocytogenes isolated from broiler chickens during processing and from six Taiwanese abattoir environments.2. Listeria monocytogenes was not detected in any cloacal (n = 120) or environmental (n = 256) samples collected before and during processing, indicating that faecal material and the environment of abattoirs were not important sources of L. monocytogenes for poultry carcases. However, 28 of 246 (11.4%; 95% CI: 7.7-16.0) rinse samples collected from carcases post-evisceration from three abattoirs were positive for L. monocytogenes.3. The only serotypes detected were 1/2a (82.1%; 95% CI: 63.1-93.9) and 1/2b (14.3%; 95% CI: 4.0-32.7), with 3.6% (95% CI: 0.1-18.3) non-typable isolates.4. Characterisation by Pulsed Field Gel Electrophoresis (PFGE) identified five PFGE types, confirming cross-contamination with L. monocytogenes during evisceration, chilling and post-chilling.5. These findings highlight the potential for cross-contamination to occur through direct contact between carcases, especially whilst in chilling tanks.

Abstract
In this study, thirteen batches of broiler chicken from an integrated Italian poultry company were investigated for the detection of Listeria monocytogenes. The prevalence was evaluated in faeces samples at farm level and after transport, caecal contents and carcass neck skin from 2 slaughterhouses (M1 and M2), for a total of 2080 samples, throughout a 27-month period. No positive results were recorded in faeces, while the overall prevalence of contamination in carcass neck skin was 26.7%. Then, 123 isolates out of 139 positive skin samples, with the prevalent serotypes 4b (76%) and 1/2b (94%) from slaughterhouses M1 and M2 respectively, were PFGE characterized, showing the presence of 18 different pulsotypes and 8 genetic clusters. The same pulsotypes were found in carcasses from different farms, but slaughtered in the same abattoir, highlighting the environmental origin of contamination. The persistence of the pathogen over long time seemed to be very likely, considering that undistinguishable pulsotypes were found in carcasses slaughtered in the same slaughterhouse after periods up to 18 months long. The implementation of cleaning and sanitation at slaughterhouse level could represent the main factor for the control of such pathogen in the poultry meat processing line.

Abstract
AbstractPoultry meat can be contaminated by different types of microorganisms during processing in processing plant. The microbiological quality of chicken carcasses and along with processing steps and environmental condition was analyzed in this study in an ISO 22000:2005 certified poultry processing plant of Kathmandu. Standard plate count method was applied for the enumeration and detection of total mesophilic bacteria, total coliform, total faecal coliform, Staphylococcus load along with selected pathogens like Salmonella spp., S. aureus, Escherichia coli, Clostridium perfringens, and Listeria spp. in chicken meat at four processing step (evisceration, final washing, frozen and market). It was observed that the level of microbial load decreased with subsequent processing phases in poultry processing plant where high level of bacteria were reduced during final washing and frozen phase. After processing poultry meat in an ISO 22000:2005 certified meat processing plant, total aerobic mesophilic count, total coliform count, total faecal coliform count, total Staphylococcus count were decreased from 6.92 to 4.45 log CFU/g, 3.49 to 2.19 log CFU/g, 2.41 to nil log CFU/g, and 3..43 to 1.99 log CFU/g respectively. Pathogenic bacteria like Salmonella spp., C. perfringens, and Listeria spp. were absent in chicken meat at the fourth processing step. Prevalence of E. coli was reduced from 37.4% to 10.2%, whereas S. aureus was decreased from 18.57% to 17.1%. It was concluded that the final washing and freezing steps were the Critical Control Point (CCP) to control microbial hazards in poultry processing phase.

Abstract
The aim of this study was to develop a nanoparticle-based cell capture system combined with a lateral flow test strip (LFT) assay for rapid detection of Campylobacter jejuni from poultry samples. The developed assay was bench-marked against the standard modified Charcoal Cefoperazone Deoxycholate Agar (mCCDA) method according to ISO16140:2003 procedures. The synthesized ferromagnetic nanoparticles (FMNs) were modified with glutaraldehyde, then functionalized with polyclonal antibodies for specific C. jejuni capture and concentration from poultry samples. After lysing captured cells, DNA from C. jejuni was amplified by PCR using the primers designed to target the hipO gene, and the PCR amplicons were detected with the lateral flow test strip assay. Following the ISO16140:2003 guidelines, the relative detection limit, and the inclusivity and exclusivity tests were determined. The results showed that the limit of detection (LOD) of the assay was 100 or 1 cfu/ml with C. jejuni in pure culture and 101-102 cfu/ml with target cells spiked in poultry sample. In addition, the inclusivity and exclusivity tests were found to be 100%. Using field chicken samples (n = 60), the assay showed relative accuracy, relative specificity, and relative sensitivity of 96.67%, 100% and 93.33%, respectively. The positive predictive values (PPV) and negative predictive values (NPV), and the kappa index of concordance (k) were calculated as 100% and 93.75%, and 0.93, respectively. The developed assay required approximately 3 h to complete and gave results comparable to those analyzed by the standard culture method, which required 5-7 days. The assay is rapid, easy-to-use, and has potential to be directly applied to C. jejuni detection in various categories of poultry samples.

Abstract
A study was conducted to investigate the prevalence of Salmonella and Campylobacter from farm to slaughter. The efficiency of trimming and water spray (490 to 588 kPa pressure) on the removal of visible fecal contamination from broiler carcasses before chilling was also investigated. Drag swabs were used to sample litter from the farm houses. Samples of ceca and carcasses without and with visible fecal contamination before and after trimming or spray washing of fecal contamination were taken during slaughter of the flocks previously visited at the farms. There was a low prevalence of Salmonella on the litter from the farms (5%) and cecum and carcasses (0%). However, Campylobacter jejuni and Campylobacter coli were present in farms' litter (100 and 58.8%, respectively), cecum samples (100 and 70.6%, respectively), and carcasses with (58.8 and 11.6%, respectively) and without (17.6 and 9.8%, respectively) visible fecal contamination. There was high prevalence of C. jejuni but at low counts and low prevalence and high counts of C. coli. Campylobacter lari was not detected in any sample. Trimming the visible fecal contamination decreased the prevalence of C. jejuni but increased occurrence of C. coli. Trimming did not reduce the counts of Campylobacter and of hygiene indicator microorganisms on the carcasses. Water shower reduced the counts of hygiene indicator microorganisms by 20%. Therefore, control measures for preventing introduction of Campylobacter and the use of good hygienic conditions are needed to warrant the microbiological quality and safety of broiler carcasses.

Abstract
Listeria monocytogenes is a common constituent of the microbiological community in poultry processing plants and can be found in low numbers on raw poultry. Raw meat is the most important source of this pathogen in commercial cooking facilities. Germicidal UV light was tested as a means to kill L. monocytogenes inoculated onto broiler breast fillets. Treatments at 800 μW/ cm(2) for 5 s to 5 min of exposure were tested against inocula of 35 to 60 cells per fillet. All fillets were sampled by rinsing in enrichment broth, and surviving pathogens were quantified using most-probable-number (MPN) analysis. Five replications each with 5 fillets per treatment were analyzed to achieve 25 sample fillets per treatment. All treatment times resulted in a significant decrease in L. monocytogenes numbers compared with paired untreated controls. Treated samples retained 0.2 to 1.5 MPN L. monocytogenes per fillet, and exposure time had no significant effect on the number of surviving cells. A 5-s treatment with germicidal UV light has potential as an intervention method to limit the transfer of L. monocytogenes on raw skinless breast fillets from a slaughter plant to a cooking plant.

Abstract
The aim of the present study was to perform microbiological isolation of Campylobacter jejuni from chilled chicken carcasses marketed in the Federal District of Brazil and to subject the strains to an antibiogram. A total of 92 samples from chilled chicken carcasses were acquired, 18 of which (19.56%) tested positive for C. jejuni. A total of 16 strains were tested for susceptibility to eight antimicrobial drugs. All 16 strains were resistant to ciprofloxacin, 15 strains to nalidixic acid, streptomycin, tetracycline, and gentamycin, 14 strains to amoxicillin, 11 strains to erythromycin, and 6 strains to chloramphenicol. The present study is the first to report on the presence of C. jejuni in chilled chicken carcasses marketed in the Federal District region of Brazil. These results may indicate flaws in certain steps of this food processing and highlight a possible public health problem due to the high level of resistance exhibited by the isolated strains.

Abstract
The objective of this study was to evaluate the use of clinical-epidemiological profiles for classifying non-laboratory-confirmed outbreaks of foodborne disease (FBD) in Catalonia between 2002 and 2006 and for elucidating associations among factors contributing to these outbreaks. A total of 275 nonfamily outbreaks were studied, of which 190 (69.1%) were laboratory confirmed and 85 (30.9%) were not. In 176 (92.6%) of laboratory-confirmed outbreaks and 69 (81.2%) of non-laboratory-confirmed outbreaks, information was obtained on contributing factors (P = 0.009). In 72% of non-laboratory-confirmed outbreaks, the etiology was assigned by using clinical-epidemiological profiles; thus, 93% of outbreaks eventually were associated with an etiology. In laboratory-confirmed outbreaks, poor personal hygiene was positively associated with norovirus (odds ratio [OR], 2.69; 95% confidence interval [CI], 1.47 to 4.89; P = 0.0007) and negatively associated with Salmonella and Campylobacter (OR, 0.54; 95% CI, 0.33 to 0.89; P = 0.01), and an unsafe source was positively associated with Salmonella and Campylobacter (OR, 4.07; 95% CI, 1.72 to 10.09; P = 0.001) and negatively associated with norovirus (OR, 0.14; 95% CI, 0.04 to 0.58; P = 0.001). No differences were found among contributing factors associated with outbreaks with a laboratory-confirmed etiology and those associated with outbreaks with an etiology assigned according to the clinical-epidemiological profiles. Clinical-epidemiological profiles are useful for determining what prevention and control strategies are appropriate to the agents involved in each community and for designing outbreak investigations.

Abstract
The goals of this study were to evaluate the efficacy of the mini VIDAS automated immunoassay chemistry system to detect Campylobacter spp. from retail broiler meat enriched in Bolton broth supplemented with lysed blood (B+B) or without blood (B-B), and to detect positive samples at 24 versus 48 h after enrichment. Retail broiler meat was enriched and tested for Campylobacter spp. with the mini VIDAS and with an agar plate. Isolates were speciated with a multiplex PCR and typed with pulsed-field gel electrophoresis (PFGE) to evaluate relatedness of isolates collected from subsamples enriched in B+B or B-B. The number of Campylobacter-positive samples by mini VIDAS was similar (P > 0.05) to the results found with traditional plating media for naturally contaminated broiler meat, regardless of whether the comparison was made between B+B and B-B, or among different meat products (breast, tenders, and thighs). More positive samples were found at 48 h of enrichment than at 24 h of enrichment (P < 0.05). A Campylobacter jejuni:Campylobacter coli ratio of 4:1 was found in this study. Most of the isolates from both subsamples (B+B and B-B) were similar or identical by PFGE analysis, except for a few samples in which the PFGE profiles of the isolates from the subsamples were different. Mini VIDAS allowed for the detection of Campylobacter spp. within 48 h after enrichment. However, the sensitivity is similar to plate media, and retail broiler samples need to be enriched for 48 h to avoid false negatives.

Abstract
A study was conducted to investigate the effect of chilling method (air or immersion) on concentration and prevalence of Escherichia coli, coliforms, Campylobacter, and Salmonella recovered from broiler chicken carcasses. For each of four replications, 60 broilers were inoculated orally and intracloacally with 1 ml of a suspension containing Campylobacter at approximately 10(8) cells per ml. After 1 day, broilers were inoculated with 1 ml of a suspension containing Salmonella at approximately 10(8) cells per ml. Broilers were processed, and carcasses were cooled with dry air (3.5 m/s at -1.1 degrees C for 150 min) or by immersion chilling in ice water (0.6 degrees C for 50 min). Concentrations of E. coli, coliforms, Campylobacter, and Salmonella recovered from prechill carcasses averaged 3.5, 3.7, 3.4, and 1.4 log CFU/ml of rinse, respectively. Overall, both chilling methods significantly reduced bacterial concentrations on the carcasses, and no difference in concentrations of bacteria was observed between the two chilling methods (P < 0.05). Both chilling methods reduced E. coli and coliforms by 0.9 to 1.0 log CFU/ml. Air and immersion chilling reduced Campylobacter by 1.4 and 1.0 log CFU/ml and reduced Salmonella by 1.0 and 0.6 log CFU/ml, respectively. Chilling method had no effect on the prevalence of Campylobacter and Salmonella recovered from carcasses. These results demonstrate that air- and immersion-chilled carcasses without chemical intervention are microbiologically comparable, and a 90% reduction in concentrations of E. coli, coliforms, and Campylobacter can be obtained by chilling.

Abstract
Campylobacter is a human pathogen associated with chicken and chicken meat products. This study was designed to examine the prevalence and number of Campylobacter on broiler chicken carcasses in commercial processing plants in the United States. Carcass samples were collected from each of 20 U.S. plants four times, roughly approximating the four seasons of 2005. At each plant on each sample day, 10 carcasses were collected at rehang (prior to evisceration), and 10 carcasses from the same flock were collected postchill. A total of 800 carcasses were collected at rehang and another 800 were collected postchill. All carcasses were subjected to a whole-carcass rinse, and the rinse diluent was cultured for Campylobacter. The overall mean number of Campylobacter detected on carcasses at rehang was 2.66 log CFU per ml of carcass rinse. In each plant, the Campylobacter numbers were significantly reduced by broiler processing; the mean concentration after chill was 0.43 log CFU/ml. Overall prevalence was also reduced by processing from a mean of > or =30 of 40 carcasses at rehang to > or =14 of 40 carcasses at postchill. Seven different on-line reprocessing techniques were applied in the test plants, and all techniques resulted in <1 log CFU/ml after chilling. Use of a chlorinated carcass wash before evisceration did not affect the postchill Campylobacter numbers. However, use of chlorine in the chill tank was related to lower numbers on postchill carcasses. Overall, U.S. commercial poultry slaughter operations are successful in significantly lowering the prevalence and number of Campylobacter on broiler carcasses during processing.

Abstract
Campylobacter jejuni (C. jejuni) is the leading cause of food-borne gastroenteritis in the United States. Detection of Campylobacter in food samples by conventional culture is cumbersome; therefore, there is a need to develop rapid and cost-effective detection and quantification methods. Eighty-four whole chicken rinses were collected at different stages of processing at three poultry processing plants. After chicken wash collection and DNA extraction, the samples were directly subjected to real-time PCR (rtPCR) without enrichment and also culture. The assay specificity was determined with a range of Campylobacter species, related, and unrelated organisms. Of the 84 samples collected 65 (77%) of the samples were positive by the rtPCR assay and 27 (32%) of the samples tested positive by direct plating to selective agar media. The results were positively concordant for 27 (32%) of the samples. The whole rtPCR assay can be completed within 90min with a detection limit of 1CFU, compared to 5-7 days for enrichment and sub culturing in selective agar. This assay is the first report of rtPCR method capable of detecting and quantifying C. jejuni from chicken rinses without an enrichment step and could be an important, rapid and quantification model for other food-borne pathogens.

Abstract
Bacillus cereus is a foodborne spore-forming bacterial pathogen that is ubiquitous in the natural environment. Infections with this pathogen manifest as diarrheal or emetic types of food poisoning. In this study, 140 samples of dried red pepper purchased in Korea were assayed for the presence of B. cereus according to the U.S. Food and Drug Administration standard culture method. A multiplex PCR assay was developed for the rapid confirmation of B. cereus as an alternative to conventional biochemical confirmation tests. The genetic diversity of B. cereus isolates was investigated using a random amplified polymorphic DNA (RAPD) assay. B. cereus was found in 84.3% of the dried red pepper samples, with an average concentration of 1.9 x 10(4) CFU/g. B. cereus could be detected and distinguished from B. thuringiensis in the multiplex PCR assay by using the BCFW1 plus BCrevnew and the K3 plus K5 primer sets designed to detect the gyrB gene of B. cereus and B. thuringiensis and the cry gene of B. thuringiensis. A RAPD assay using the OPG 16 and MUP 3 primers was used to successfully distinguish among isolates, thus elucidating the genetic diversity of B. cereus isolates. The discriminating ability of the OPG 16 primer (142 types) was about threefold higher than that of MUP 3 (52 types) in the RAPD assay.

Abstract
The presence of Campylobacter was assessed in different samples of poultry, pork and beef meat and carcasses from slaughterhouses, production plants and retail level. An introductory study from 1997 to 1999, had the purpose of establishing the optimum dilution to detect changes in prevalence and allowed a semi-quantitative estimation of poultry and pork contamination. Following this, between 2000 and 2003, 4254 samples were taken in order to study the trends. The poultry matrixes represented the greatest number and the most highly contaminated samples, with 30.9% (in 0.01 g) positive samples, 18.7% (in 1 g), 46.9% (in 25 g) and 19.6% (in 0.01 g) for broiler carcasses, broiler fillets, prepared chicken and layer carcasses, respectively. Broiler carcasses and fillets sampled at retail level were significantly less contaminated than samples from production plants. Pork, beef and veal samples were rarely contaminated and, where contamination existed, it was at a low prevalence (maximum 5.0%). The high and unvarying prevalence of Campylobacter in poultry necessitates the implementation of intervention measures at the primary production level, in addition to methods of minimizing cross-contamination at the processing level. A survey plan in line with the present study could be used in the future to monitor the effects of the planned measures and performance objectives and to follow the evolution of Campylobacter contamination at all stages of the food chain, in accordance with European legislation.
