“…Inadequate cleaning and disinfection and short downtime of the broiler house between flocks may be a major source of Campylobacter carryover as studies confirmed Campylobacter in dust swabs from the interior of the barn and the drinking water system prior to or during flock placement [43], [44], [70], [71], [91]. The cycle of contaminated flocks is self-perpetuating if chicks are being placed in an already contaminated environment, in this SR 83% of the studies that reported carryover concluded persistent Campylobacter genotypes could be identified through several cycles [49], [70], [72]–[75]. In agreement with Adkin et al [12] and Newell et al [16] inputs such as clean litter and feed into the barn were not likely sources of Campylobacter to young broilers.…”

“…While carry-over was not an objective of this SR, there were 5 longitudinal prevalence studies and one cohort study that demonstrated carry-over of Campylobacter genotypes through two or more flock cycles and also isolated matching genotypes in samples taken in the indoor barn environment demonstrating residual contamination acted as a source for the next broiler cycle [49], [70], [72]–[75].…”

A Systematic Review Characterizing On-Farm Sources of Campylobacter spp. for Broiler Chickens

Campylobacter and antimicrobial-resistant Campylobacter are frequently isolated from broiler chickens worldwide. In Canada, campylobacteriosis is the third leading cause of enteric disease and the regional emergence of ciprofloxacin-resistant Campylobacter in broiler chickens has raised a public health concern. This study aimed to identify, critically appraise, and synthesize literature on sources of Campylobacter in broilers at the farm level using systematic review methodology. Literature searches were conducted in January 2012 and included electronic searches in four bibliographic databases. Relevant studies in French or English (n = 95) conducted worldwide in any year and all study designs were included. Risk of Bias and GRADE criteria endorsed by the Cochrane collaboration was used to assess the internal validity of the study and overall confidence in the meta-analysis. The categories for on-farm sources were: broiler breeders/vertical transfer (number of studies = 32), animals (n = 57), humans (n = 26), environment (n = 54), and water (n = 63). Only three studies examined the antimicrobial resistance profiles of Campylobacter from these on-farm sources. Subgroups of data by source and outcome were analyzed using random effect meta-analysis. The highest risk for contaminating a new flock appears to be a contaminated barn environment due to insufficient cleaning and disinfection, insufficient downtime, and the presence of an adjacent broiler flock. Effective biosecurity enhancements from physical barriers to restricting human movement on the farm are recommended for consideration to enhance local on-farm food safety programs. Improved sampling procedures and standardized laboratory testing are needed for comparability across studies. Knowledge gaps that should be addressed include farm-level drug use and antimicrobial resistance information, further evaluation of the potential for vertical transfer, and improved genotyping methods to strengthen our understanding of Campylobacter epidemiology in broilers at the farm-level. This systematic review emphasizes the importance of improved industry-level and on-farm risk management strategies to reduce pre-harvest Campylobacter in broilers.

“…A high similarity of genetic patterns of C. jejuni isolates suggested that some isolates within the identified RAPD types were closely related or even of clonal origin (22). Genetic relatedness of C. jejuni strains may indicate for such strains to be typical for particular niche and for unique ones to stay there only temporarily (16).…”

“…2). It was noted for a number of C. jejuni genotypes that the RAPD patterns noticeably differed in raw poultry at retail due to the poultry origin and the method/primer used, with a higher number of unique RAPD patterns noted for samples with more diverse contamination sources considered (10,22). For instance, among 48 isolates from raw poultry operation 10 RAPD profiles with OPA11 primer were found with 22 distinct PCR/RFLP profiles identified among 182 C. jejuni/C.…”

The aim of the work was to find out what is the prevalence and burden of Campylobacter sp. in the poultry exudates, what are the predominant species, how diverse they are, and can poultry exudates be considered as the essential carriers of campylobacters posing a health risk of campylobacteriosis in Poland. Broilers' and turkeys' exudates, collected directly from the bulk containers at the day of delivery were subjected to pre-enrichment and direct plate counting according to ISO 10272 (1995) with presumptive C. jejuni strains subjected to confirmatory genetic identification by the nested PCR and RAPD typing. The results indicated that over 90% of the exudates tested carried Campylobacter sp., with their number being significantly higher in broilers' (10 3 to10 5 cfu mL -1 ) compared to turkeys' (10 2 to 10 4 cfu mL -1 ) (P≤0.05), and essentially higher (P≤0.05) for the broiler parts' "skin on" exudates. C. jejuni was the only species present in the turkeys' and predominant in broilers' parts' exudates. RAPD-typing of the isolates revealed 14 distinct RAPD types with the majority of C. jejuni isolates considered to be closely related.
