Sources of Poultry Meat Contamination with Thermophilic Campylobacter before Slaughter
نویسندگان
چکیده
The possible sources of Campylobacter spp. in poultry meat before slaughter were studied by examining samples of feathers, cloaca swabs, litter swabs, transport coops, rinse water from coop washing equipment, and chicken breast supports in the slaughter line just before stunning. The samples were collected from 8 broiler houses and from 8 different producers, from a poultry integration system in southern Brazil. The study was carried out over a 12-month period, and each broiler house was sampled in three consecutive flocks, for a total of 24 flocks/broiler house. Campylobacter was found in 79.2% of the feather samples, followed by cloacal swabs (75.0%) and transport coop (50.0%), litter (37.5%), breast support (33.3%) and coop rinse water (25.0%) samples. Considering the combined results of cloacal, feather and litter samples, 21 (87.5%) of the 24 chicken batches contained thermophilic Campylobacter in at least one of these samples prior to slaughter. Thermophilic Campylobacter were found in 22 of 24 chicken batches destined to slaughter, corresponding to 91.7% contaminated batches.

متن کاملCampylobacter in Poultry: Ecology and Potential Interventions.
Avian hosts constitute a natural reservoir for thermophilic Campylobacter species, primarily Campylobacter jejuni and Campylobacter coli, and poultry flocks are frequently colonized in the intestinal tract with high numbers of the organisms. Prevalence rates in poultry, especially in slaughter-age broiler flocks, could reach as high as 100% on some farms. Despite the extensive colonization, Cam...

This study aimed to analyse the diversity of the Campylobacter jejuni population in broilers and to evaluate the major source of contamination in poultry meat. Eight rearing cycles over one year provided samples from three different broiler farms processed at the same slaughterhouse. A total of 707 C. jejuni were isolated from cloacal swabs before slaughter and from the breast skin of carcasses...

Campylobacteriosis is one of the most important bacterial food-borne illnesses in humans. One significant source of infection is the handling and consumption of poultry meat, although other sources also contribute considerably. Controlling Campylobacter in broilers reduces the human burden of illness. Broilers can easily become colonised with Campylobacter and preventive measures in primary pro...
