A systematic review and meta-analysis of the sources of Campylobacter in poultry production (preharvest) and their relative contributions to the microbial risk of poultry meat. Poult Sci 2023; 102:102905. [PMID: 37516002 PMCID: PMC10405099 DOI: 10.1016/j.psj.2023.102905] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/18/2023] [Accepted: 06/24/2023] [Indexed: 07/31/2023] Open
Abstract
A systematic review and meta-analysis were conducted to idetnify the relative contributions of the sources of Campylobacter in poultry live production to Campylobacter prevalence of broiler meat. The keywords of Campylobacter, prevalence, live production, and broiler were used in Google Scholar to address the research interest. A total of 16,800 citations were identified, and 63 relevant citations were included in the meta-analysis after applying predetermined inclusion and exclusion criteria. A generalized linear mixed model approach combined with logit transformation was used in the current meta-analysis to stabilize the variance. The analysis revealed that Campylobacter is ubiquitous in the poultry house exterior environment including surroundings, wildlife, domestic animals, and farm vehicle, with a predicted prevalence of 14%. The recovery of Campylobacter in the interior environment of the poultry house is far less abundant than in the exterior, with a prevalence of 2%, including litter, water, insects, mice, feed, and air. A lack of evidence was observed for vertical transmission due to the day-old chicks being free of Campylobacter from 4 studies identified. Live birds are the predominant carrier of Campylobacter, with a predicted prevalence of 41%. Transportation equipment used for live haul had an overall prevalence of 39%, with vehicles showing a predicted prevalence of 44% and crates with a predicted prevalence of 22%. The results of this meta-analysis highlight the need to implement effective biosecurity measures to minimize the risk of Campylobacter in poultry meat, as human activity appears to be the primary factor for Campylobacter introduction.

Abstract
AbstractBeef is a source of human Campylobacter infections. Antimicrobial treatment is needed when patients are immunocompromised or have other comorbidities. Therefore, we investigated the prevalence and antimicrobial resistance of Campylobacter spp. in beef cattle in Japan. Rectal swab samples were collected from 164 beef cattle at an abattoir between March 2021 and August 2021, and Campylobacter spp. were isolated from 94 (57.3%) cattle. C. jejuni and C. coli were isolated from 68 and 26 cattle, respectively. For Campylobacter jejuni, the resistant rates against ampicillin, tetracycline and ciprofloxacin were 20.6, 75.0 and 64.7%, respectively. For C. coli, the resistant rates against ampicillin, tetracycline and ciprofloxacin were 53.8, 76.9 and 88.5%, respectively. No Campylobacter isolates were resistant to erythromycin. By multilocus sequence typing, C. jejuni and C. coli isolates were classified into 22 and 2 sequence types (STs). The top three STs of C. jejuni were ST806 (12 isolates), ST21 (nine isolates), and ST459 (eight isolates). The most frequent ST of C. coli was ST1068 (23 isolates). The results suggest that Campylobacter spp. are prevalent in the gastrointestinal tract of beef cattle slaughtered at abattoirs. Furthermore, the administration of erythromycin is effective against human campylobacteriosis caused by beef consumption. Monitoring the prevalence and antimicrobial resistance of Campylobacter spp. in beef cattle could be useful for managing the risk of human campylobacteriosis.

Abstract
As free-living crows are a potential source of Campylobacter infections in broilers and cattle, we characterized Campylobacter spp. isolated from crows
using multilocus sequence typing and antimicrobial susceptibility testing. We obtained 82 samples from 27 birds captured at seven different times using a trap set in Tochigi prefecture,
Japan. Campylobacter jejuni was isolated from 55 (67.1%) of the 82 samples and classified into 29 sequence types, of which 21 were novel. Tetracycline and streptomycin
resistance rates were 18.2% and 3.6%, respectively. These results show that most types of C. jejuni infecting crows differ from those isolated from humans, broilers, and
cattle. Thus, the importance of free-living crows as reservoirs of Campylobacter infections in broilers and cattle may be limited.

Abstract
Chicken is a major source of human campylobacteriosis. Chicken meat originates not only
from broilers but also from spent layers; however, few reports have documented the
prevalence and antimicrobial resistance of Campylobacter spp. in layers
in Japan. Therefore, we investigated the prevalence and antimicrobial susceptibility of
Campylobacter spp. in 47 layer farms in Japan. Fecal samples were
collected from the youngest and oldest flocks on the farm, and
Campylobacter spp. was isolated from 46/47 (97.9%) farms. Among the
C. jejuni isolates, the resistance rates to ampicillin, tetracycline,
and ciprofloxacin were 29.6%, 22.2%, and 19.8%, respectively. The ciprofloxacin resistance
rate (7.3%) in C. jejuni isolated from old flocks was significantly
(P<0.01) lower than that in young flocks (32.5%).

Recommended Practices to Eliminate Campylobacter from Live Birds and Chicken Meat in Japan. Food Saf (Tokyo) 2021; 9:57-74. [PMID: 34631334 PMCID: PMC8472096 DOI: 10.14252/foodsafetyfscj.d-20-00021] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2020] [Accepted: 06/10/2021] [Indexed: 01/13/2023] Open
Abstract
Campylobacter food poisoning
is one of the major bacterial foodborne diseases
resulting in numerous outbreaks worldwide.
Particularly in Japan, one-fourth of the total
food poisoning is caused by Campylobacter
jejuni/coli. Raw and/or undercooked
poultry meat and meat products are known as the
main cause of campylobacteriosis. Consequently,
effective and immediate actions are needed to
eliminate or at least reduce campylobacteriosis.
This study aimed at examining the Japanese food
regulation system, comparing it with those in the
USA and Australia, and making necessary
recommendations for a better control of
campylobacteriosis in Japan. The study was
conducted by a thorough investigation of published
literatures, governmental documents, statistical
and epidemiological data and public information.
The results led to recommendations that the
Japanese food regulation authority should consider
the following suggestions in order to control
campylobacteriosis: 1) assess the
Campylobacter safety at the end
of processing stage of chicken supply chain based
on risk assessment using quantitative/qualitative
baseline data collected over Japan, 2) establish a
national Campylobacter strategy,
including specific campylobacteriosis reduction
goals and criteria, and 3) provide the small food
business operators with sufficient training and
support to implement a Hazard Analysis Critical
Control Points (HACCP) as an obligatory food
safety requirement. It is acknowledged that it
would be difficult to apply foreign regulations
directly to Japanese food regulation system due to
differences in food culture, regulation, industry
structure, and data collection systems. Thus,
flexible application is required. Finding and
conducting effective
Campylobacter control measures
can decrease contaminated live birds and chicken
meat in Japan, home to a unique food culture of
eating raw and/or undercooked chicken meat called
Torisashi such as sashimi, tataki and yubiki
chicken. Consequently, potentially available
research data may be instrumental in finding
solutions for reducing campylobacteriosis.
Eliminating Campylobacter food
poisoning cases in Japan will be a significant
achievement in ensuring Japanese and global food
safety.

Abstract
Food of animal origin, especially meat products, represent the main vehicle of foodborne pathogens and so are implicated in foodborne outbreaks. Poultry meat is a widely consumed food in various forms, but it is also a reservoir of thermotolerant Campylobacter and Salmonella bacterial species. To assess human health risks associated with pathogenic bacteria in poultry meat, the use of quantitative microbial risk assessment (QMRA) has increased over the years as it is recognized to address complex food safety issues and is recommended by health authorities. The present project reviewed poultry meat QMRA, identified key steps of the farm-to-fork chain with significant impacts on food safety, highlighted current knowledge gaps, and provided risk mitigation advices. A PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)-based systematic analysis was carried out and enabled the collection of 4056 studies including 42 QMRA kept for analysis after screening. The latter emphasized Campylobacter spp. and Salmonella spp. contaminations during the consumer stage as the main concern. The role of consumer handling on cross-contamination and undercooking events were of major concern. Thus, proper hygiene and safety practices by consumers have been suggested as the main intervention and would need to be followed with regular surveys to assess behavior changes and reduce knowledge gaps.

Abstract
Campylobacter spp. is one of the most frequent causes of foodborne gastroenteritis. This study aimed to estimate the prevalence and to identify the risk factors of farm-level Campylobacter infection in meat-type chicken flocks. A cross-sectional study was conducted in two selected districts of Bangladesh over the period of January to July 2019. A total of 84 pooled cloacal swab samples were collected from 84 broiler and cockerel farms. Data on farm management, biosecurity, and hygiene practices were collected using a structured questionnaire through a face-to-face interview during sampling. Thereafter, Campylobacter spp. were isolated through bacteriological culture and identified by Gram staining and biochemical tests. Furthermore, the isolates were confirmed using the polymerase chain reaction by targeting the 16S rRNA gene. The risk factors were analyzed at the farm level using multivariable logistic regression with the significant levels of P-value ≤ 0.05. Among the 84 farms, 34 were positive to Campylobacter spp.; thus, the prevalence was estimated to be 40.5% (95% CI: 30.1%-51.8%). In risk factor analysis, the following factors were found to be significantly associated with Campylobacter infection: shed older than five years, birds older than 30 days, flock size with more than 1500 birds, downtime less than seven days, no disinfection of shed surroundings during rearing, rice husk as litter materials, and less than 10 years of farming experience. The study identified the factors that could lead to the setting of effective interventions in controlling Campylobacter infection in chickens to reduce campylobacteriosis in humans through meat consumption.

Abstract
The effects of climatic elements on Salmonella contamination of chicken meat were investigated. Logistic regression analysis was performed to evaluate the association between Salmonella isolation, for 240 chicken samples purchased from March 2015 to February 2017, and climatic elements, over 65 days of chicken rearing. Salmonella was isolated from 143 samples (59.6%), and the most dominant serovars identified were Infantis (77/240, 32.1%) and Schwarzengrund (56/240, 23.3%). Previous studies have reported S. Schwarzengrund contamination of broiler chickens only in western Japan; however, in the present study, S. Schwarzengrund was also isolated from meat produced in eastern Japan-20% (12/60) in the C prefecture to 36.4% (8/22) in the Y prefecture-suggesting that S. Schwarzengrund-contaminated areas have expanded towards eastern Japan. Air temperature showed a significant negative association with S. Schwarzengrund isolation for chicken meat produced during periods with rising temperature (spring and summer) [odds ratio (OR), 0.894 to 0.935; P<0.01]. Moreover, the risk of S. Schwarzengrund contamination of chicken meat was higher during spring (OR, 3.951; P=0.008) and winter (OR, 4.071; P=0.006) than during summer. Effects of climatic elements and differences in contamination risk across seasons were not observed for any Salmonella serovars and only S. Infantis, which could be attributed to differences in transmission patterns and vehicles among Salmonella serovars. These findings are valuable for understanding the dynamics of S. Schwarzengrund dissemination in broiler farms.

Abstract
Campylobacter spp. are the leading causes of bacterial human gastroenteritis worldwide; being poultry farms the main source of infections. In order to obtain information on prevalence and diversity of Campylobacter-infected flocks in the North of Spain, fourteen farms were studied between autumn and spring in 2014 and 2015, respectively. Moreover, virulence genes involved in pathogenicity and antimicrobial resistance were investigated. A survey about preventive hygiene practices at farms was performed to determine the risky practices that could contribute to the presence of Campylobacter in this step of the poultry food chain. Testing the presence of Campylobacter spp. showed 43 % of the farms were positive during autumn, whereas only 31 % were positive in spring. A very high prevalence within-flock was observed (43.1 % to 88.6 %) and C. jejuni was the most prevalent species in both periods. Genotyping by pulsed field gel electrophoresis (PFGE) showed a high heterogeneity among farms (309 isolates clustered into 21 pulsotypes). Virulence genes were present in all C. jejuni isolates while cdtA and cdtC were absent in C. coli. On the contrary, the latter showed higher antimicrobial resistance than C. jejuni. This study suggests that environment might be one of the main sources for Campylobacter transmission, as water supply seemed to be a clear cause of the contamination in a specific farm. However, in other farms other environmental factors contributed to the contamination, confirming the multifactorial origin of Campylobacter colonization in broilers. Therefore, biosecurity measures in farms are crucial to reduce Campylobacter contamination, which may have important implications for human and animal health.

Abstract
According to the annual food poisoning statistics compiled by the Ministry of
Health, Labour and Welfare (MHLW) in Japan, Campylobacter
replaced Salmonella and Vibrio
parahaemolyticus as the leading bacterium responsible for food
poisoning in 2003. Although in 2006 the number of cases of
Campylobacter food poisoning was 3,439 on the basis of the
MHLW statistics, it was estimated to be 1,545,363 on the basis of active
surveillance, suggesting that passive surveillance yields an incidence about 450
times lower than that revealed by active surveillance. Epidemiological
investigations of Campylobacter food poisoning in Japan have
shown that chicken meat and its products are the most important sources of
infection, as is the case in other industrialized nations. Over the last two
decades, the consumption of fresh raw chicken meat and liver has been increasing
in Japan. Although the MHLW recommends that chicken meat should only be eaten
after thorough cooking, it is likely to account for much of the increased
incidence of human campylobacteriosis. In response to this situation, the Expert
Committee on Microorganisms/Viruses, Food Safety Commission of Japan, Cabinet
Office, Government of Japan (FSCJ) has revised the previous risk profile of
C. jejuni/coli in chicken meat by adding
new findings for 2018. Moreover, the MHLW revised the Poultry Slaughtering
Business Control and Poultry Meat Inspection Act in 2014 aiming at stepwise
introduction of the Hazard Analysis Critical Control Point (HACCP) system into
poultry processing plants. Subsequently, the Japanese government amended the
Food Sanitation Act in 2018, requiring all food business operators to implement
hygiene control based on HACCP principles as a general rule. This paper reviews
the current status of Campylobacter food poisoning due to
consumption of chicken meat in Japan and extracts the issues underlying each
step of the food supply chain in order to examine the implementation of
effective measures for risk management.

Abstract
Chicken meat represents an important source of Campylobacter infections of humans world-wide. A better understanding of Campylobacter epidemiology in commercial chicken flocks will facilitate the development of more effective intervention strategies. We developed a gene-specific parallel sequencing approach that efficiently indicated genetic diversity in farm-derived samples and revealed Campylobacter genotypes that would not be detected using microbiological culture. Parallel sequencing of the porA nucleotide fragment identified a different pattern of diversity in broiler flocks compared with broiler-breeder flocks at both individual bird and flock levels. Amongst the flocks tested, broiler flocks and individual birds were dominated by one or two porA fragment types whereas co-dominance with up to six porA fragment types was evident in breeder birds. A high proportion (83.6-93.3%) of porA variants were shared between broiler and breeder flocks. The porA-based diversity profiling could be a useful addition to the repertoire of tools employed to attribute potential sources of contamination for broiler flocks, including the environment, wild animals or other chickens. This approach can be extended to include other loci within Campylobacter and developed for molecular epidemiology studies of other bacterial species.

Abstract
Association of the water- and foodborne pathogen Campylobacter jejuni with free-living Acanthamoeba spp. trophozoites enhances C. jejuni survival and resistance to biocides and starvation. When facing less than optimal environmental conditions, however, the Acanthamoeba spp. host can temporarily transform from trophozoite to cyst and back to trophozoite, calling the survival of the internalized symbiont and resulting public health risk into question. Studies investigating internalized C. jejuni survival after A. castellanii trophozoite transformation have neither been able to detect its presence inside the Acanthamoeba cyst after encystation nor to confirm its presence upon excystation of trophozoites through culture-based techniques. The purpose of this study was to detect C. jejuni and Mycobacterium avium recovered from A. polyphaga trophozoites after co-culture and induction of trophozoite encystation using three different encystation methods (Neff's medium, McMillen's medium and refrigeration), as well as after cyst excystation. Internalized M. avium was used as a positive control, since studies have consistently detected the organism after co-culture and after host excystation. Concentrations of C. jejuni in A. polyphaga trophozoites were 4.5 × 105 CFU/ml, but it was not detected by PCR or culture post-encystation. This supports the hypothesis that C. jejuni may be digested during encystation of the amoebae. M. avium was recovered at a mean concentration of 1.9 × 104 from co-cultured trophozoites and 4.4 × 101 CFU/ml after excystation. The results also suggest that M. avium recovery post-excystation was statistically significantly different based on which encystation method was used, ranging from 1.3 × 101 for Neff's medium to 5.4 × 101 CFU/ml for refrigeration. No M. avium was recovered from A. polyphaga cysts when trophozoites were encysted by McMillen's medium. Since C. jejuni internalized in cysts would be more likely to survive harsh environmental conditions and disinfection, a better understanding of potential symbioses between free-living amoebae and campylobacters in drinking water distribution systems and food processing environments is needed to protect public health. Future co-culture experiments examining survival of internalized C. jejuni should carefully consider the encystation media used, and include molecular detection tools to falsify the hypothesis that C. jejuni may be present in a viable but not culturable state.

Abstract
To demonstrate the effect of climatic elements on Campylobacter colonization in broiler chickens reared in Japan, the correlation between Campylobacter isolated from chickens (191 of 236 flocks, 80.9%) between 2008 and 2012 and climatic elements was analyzed by logistic regression. We divided the rearing process into 13 terms of 5 d each (total: 65 d). Terms were numbered backwards, wherein a 0-term lag was considered as the sampling day plus 4 d before sampling; 1-term lag was the 5-d term before the 0-term lag, and so on, until the 12-term lag. We obtained climatic data tracing back from the 0-term to the 12-term lags. For evaluation in each season, we divided chickens reared during periods of rising temperature (spring, summer) and decreasing temperature (autumn, winter). Air temperature showed a positive correlation with Campylobacter colonization from the 0- to 12-term lags in chickens reared during the period of rising temperature (odds ratio [OR], 1.069 to 1.104), and from the 0- to 4- and 6-term lags (OR, 1.079 to 1.105) in chickens reared during the period of decreasing temperature. The strong positive effect of air temperature on Campylobacter colonization, particularly during the period of rising temperature, may be associated with the effect on the Campylobacter environmental sources and/or vectors. A positive correlation was observed between Campylobacter colonization and humidity when chicken houses were empty and new chicks were introduced (from the 9- to 12-term lags) during the period of decreasing temperature (OR, 1.076 to 1.141). Thus, high humidity would be an important factor causing carry-over of Campylobacter infection during the period of decreasing temperature. We also found that solar radiation increased Campylobacter colonization during the period of decreasing temperature, from the 2- to 8-term lags, except for the 4- and 5-term lags, in Japan. The results of this study demonstrate the effects of air temperature, humidity, and solar radiation on Campylobacter colonization in broiler chickens, and are potentially important for developing strategies to reduce the risk of Campylobacter contamination in broiler chickens.

Abstract
Campylobacter are bacteria associated with human foodborne disease worldwide. Poultry and poultry products are generally considered as a main source of these organisms. Compared to temperate zones, baseline information on Campylobacter in tropical regions is limited. Thus, the objectives of the present study were 1) to determine the prevalence of Campylobacter in Thai broiler flocks and 2) to investigate the association between climatic factors (i.e., rainfall, ambient temperature, and relative humidity) and Campylobacter colonization status of broiler flocks in Thailand. A total of 442 commercial broiler flocks reared in the central and northeastern regions of Thailand during 2012 to 2014 were investigated. Campylobacter positive status was identified in 252 examined flocks (57.01%; 95% CI 52.39 to 61.63%). Prevalence of Campylobacter in the northeastern region (54.46%; 95% CI 44.76 to 63.83%) was slightly lower than that of the central region (57.77%; 95% CI 52.47 to 62.90%). More than 65% of Campylobacter positive flocks in the central and northeastern regions had within-flock prevalence higher than 75%. Generalized estimating equations (GEE) revealed that the increased rainfall and relative humidity were associated with the increase of Campylobacter colonization in broiler flocks (P ≤ 0.05), while no relationship between ambient temperature and Campylobacter colonization status was identified.

Abstract
BACKGROUND The need for organic food of animal origin has increased rapidly in recent years. However, effects of organic animal husbandry on food safety have not been rigorously tested especially in meat turkey flocks. This study provides for the first time an overview on the prevalence and genetic diversity of Campylobacter species (spp.) in five organic meat turkey farms located in different regions in Germany, as well as on potential risk factors of bacterial spreading. Thirty cloacal swabs as well as water samples and darkling beetles were collected from each flock and examined for the presence of Campylobacter by conventional and molecular biological methods. The isolates were genotyped by flaA-RFLP. RESULTS Campylobacter spp. were detected in cloacal swabs in all 5 turkey flocks with prevalence ranged from 90.0 to 100 %. 13 cloacal swabs collected from birds in farm III and IV were harboured mixed population of thermophilic campylobacters. In total, from 158 Campylobacter isolated from turkeys 89 (56.33 %) were identified as C. coli and 69 (43.76 %) as C. jejuni. Three Campylobacter (2 C. jejuni and 1 C. coli) were detected in drinkers of two farms and 3 C. coli were isolated from darkling beetles of one farm. No Campylobacter were isolated from main water tanks. flaA-RFLP assay showed that turkey farms can harbour more than one genotype. In a single turkey two different genotypes could be detected. The genotypes of campylobacters isolated from water samples or beetles were identical with those isolated from turkeys. No effect was found of some environmental parameters [ammonia concentration (NH3), carbon dioxide concentration (CO2), relative humidity (RH) and air temperature)] on Campylobacter prevalence in organic turkey farms. Additionally, drinking water and darkling beetles might be considered as risk factors for the spreading of Campylobacter in turkey flocks. CONCLUSIONS This study highlights the high prevalence and genotypic diversity of Campylobacter spp. isolated from organic turkey flocks. Further research is needed to assess other potential risk factors responsible for bacteria spreading in order to mitigate the spread of Campylobacter in organic turkey flocks by improving biosecurity control measures.

Abstract
AIM To elucidate the distribution and circulation dynamics of Campylobacter and Salmonella in Japanese chicken broiler flocks. METHODS AND RESULTS A 2-year investigation of the distribution of Campylobacter and Salmonella was conducted in 25 broiler flocks at nine farms in Japan from 2013 to 2014. Campylobacter and Salmonella tested positive in 11 (44·0%) and 24 (96·0%) broiler flocks respectively. One hundred and ninety-five Campylobacter and 184 Salmonella isolates were characterized into 12 Campylobacter (including two novel genotypes) and three Salmonella MLST genotypes. Only Salmonella isolation between caecal and environmental samples were significantly correlated. Further, one litter sample tested positive for Salmonella before new chicks were introduced. The Campylobacter strains rapidly lost culturability within 2-18 days; in contrast, the Salmonella strains survived from 64-211 days in artificially inoculated water samples. CONCLUSION No persistent circulation-mediated Campylobacter contamination was observed. In contrast, circulation of Salmonella in broiler houses was seen, apparently due to the litter excreted from broiler flocks, as well as Salmonella-contaminated water and feed. SIGNIFICANCE AND IMPACT OF THE STUDY This paper provides the distribution, genotypic data and circulation dynamics of Campylobacter and Salmonella as recently observed in Japanese chicken broiler farms.

Abstract
Campylobacter is a food-borne zoonotic pathogen that causes human gastroenteritis worldwide. Campylobacter bacteria are commensal in the intestines of many food production animals, including ducks and chickens. The objective of the study was to determine the prevalence of Campylobacter species in domestic ducks, and the agar dilution method was used to determine resistance of the isolates to eight antibiotics. In addition, multilocus sequence typing (MLST) was performed to determine the sequence types (STs) of selected Campylobacter isolates. Between May and September 2012, 58 duck farms were analyzed, and 56 (96.6%) were positive for Campylobacter. Among the isolates, 82.1% were Campylobacter jejuni, 16.1% were C. coli, and one was unidentified by PCR. Of the 46 C. jejuni isolates, 87.0%, 10.9%, and 21.7% were resistant to ciprofloxacin, erythromycin, and azithromycin, respectively. Among the C. coli isolates, all 9 strains were resistant to ampicillin, and 77.8% and 33.3% were resistant to ciprofloxacin and azithromycin, respectively. The majority of the Campylobacter isolates were classified as multidrug resistant. Twenty-eight STs were identified, including 20 STs for C. jejuni and 8 STs for C. coli. The most common clonal complexes in C. jejuni were the ST-21 complex and the ST-45 complex, while the ST-828 complex predominated in C. coli. The majority of isolates were of STs noted in ducks and humans from earlier studies, along with seven STs previously associated only with human disease. These STs overlapped between duck and human isolates, indicating that Campylobacter isolates from ducks should be considered potential sources of human infection.

Abstract
Rectal contents of beef cattle and pigs were collected between October 2010 and February 2011 in Japan. Campylobacter jejuni were isolated from 36.0% (90/250) of beef cattle from 88.0% (22/25) of beef farms. C. coli were isolated from 3.6% (9/250) of beef cattle from 16.0% (4/25) of beef farms and from 42.4% (106/250) of pigs from all 25 pig farms. As to enrofloxacin, 40.0% (36/90) of C. jejuni isolates and 66.7% (6/9) of C. coli isolates from beef cattle and 44.3% (47/106) of C. coli isolates from pigs were resistant. Additionally, 15.1% (16/106) of C. coli isolates from pigs were resistant to erythromycin and enrofloxacin. The high prevalence of Campylobacter carriers and significant antimicrobial resistance of the isolates were found.

Abstract
To investigate the prevalence and characterization of foodborne pathogens [Campylobacter spp., Shiga toxin-producing Escherichia coli (STEC), Listeria monocytogenes and Salmonella spp.] in dairy cows, rectal content grab samples were collected from 250 dairy cows reared on 25 dairy farms in eastern Japan from December 2010 through February 2011. Campylobacter jejuni was isolated from 106 (42%) cows on 23 (92%) farms, STEC O157 from three cows on one farm, L. monocytogenes from three cows on another three farms and Salmonella enterica subsp. enterica serovar Typhimurium from eight cows on another farm. STEC O26 was not isolated from any of the dairy farms investigated. The results suggest that C. jejuni is widespread in dairy farms in eastern Japan.

Abstract
Two turkey flocks (male and female) and the environment of their house were investigated for the presence of thermophilic Campylobacter. Sample DNA was extracted directly from fecal material and environmental samples. Bacterial identification was done using a modified Campylobacter species specific multiplex PCR. The times needed for colonization and prevalence in male and female turkeys were determined independently. All environmental samples collected before restocking were negative in the PCR analysis, showing a good hygiene and biosecurity system. The first positive PCR results were obtained in drinking water samples at 6 d of age. Colonization occurred between the second and third week of age, starting in female birds and then followed by the males. Campylobacter jejuni was detected by multiplex PCR at first; later on, Campylobacter coli and mixtures of both were seen. After the 9 wk of age, the colonization of the flocks was completed. Great attention should be given to drinking water as a supposed source of Campylobacter contamination. Multiplex PCR proved to be a rapid, sensitive, and cheap tool for the diagnosis of Campylobacter contamination.

Abstract
SUMMARYThis study determined the prevalence and antimicrobial susceptibility of Salmonella isolated from broiler flocks in Japan. Caecal dropping samples were collected from 288 broiler flocks between November 2007 and February 2010. Salmonella was prevalent in 248 (86·1%) broiler flocks. The top three serovars were S. Infantis, S. Manhattan and S. Schwarzengrund. S. Infantis was found in all regions tested in this study. However, S. Manhattan and S. Schwarzengrund were frequently found only in the western part of Japan. High antimicrobial resistance rates were observed against oxytetracycline (90·2%), dihydrostreptomycin (86·7%) and ampicillin (36·5%), and 258 (90·5%) of 285 isolates were resistant to two or more antimicrobial agents. Interestingly, 26·3% of isolates were resistant to ceftiofur, especially 38·1% of S. Infantis isolates, although its use in broilers has not been approved in Japan. This study showed that Salmonella is highly prevalent (86·1%) in Japanese broiler flocks, that 90·5% of Salmonella isolates were multidrug-resistant, and that S. Infantis frequently exhibited resistance to cephalosporin antimicrobial agents.

Abstract
SUMMARYJapanese weather data for areas that produced Campylobacter spp.-positive chicken products were compared with those for areas producing negative samples. Regarding samples produced during the period of rising temperature (spring and summer), the mean weekly air temperatures for Campylobacter-positive samples were higher than those for negative samples for the period of the week in which the samples were purchased (18·7°C vs. 13·1°C, P=0·006) to a 12-week lag (12 weeks before purchasing samples; 7·9°C vs. 3·4°C, P=0·009). Significant differences in weekly mean minimum humidity and sunshine duration per day were also observed for 1- and 2-week lag periods. We postulated that the high air temperature, high humidity and short duration of sunshine for the chicken-rearing period increased Campylobacter colonization in chickens during the period of rising temperature. Consequently, the number of Campylobacter-contaminated chicken products on the market in Japan may fluctuate because of the climatic conditions to which reared chickens are exposed.
