| Popis: | Campylobacterinfection is the leading foodborne bacterial gastroenteritis worldwide and the bacteria are frequently isolated from the intestines of chickens. The broiler meat contamination withC. jejuniorC. colimay occur during slaughter processing. The aim of the study was to investigate the prevalence ofCampylobacterin poultry flocks and the corresponding broiler carcasses in 15 districts (voivodeships) all over Poland. A total of 128 samples from broiler flocks and the corresponding carcasses were collected between February 2011 and April 2013. TheCampylobacterisolation and species identification were performed according to ISO 10272-1 standard and with PCR. It was found that 112 flock (96.5%) were contaminated with campylobacters, eitherC. jejuni(77 samples; 68.7%) orC. coli(35 flocks; 31.3%). Analysis of the corresponding chicken carcasses tested after chilling revealed that 77 out of 128 (60.2%) samples were positive forCampylobacter, eitherC. jejuni(58; 75.3%) orC. coli(19; 24.7%). Most of the carcasses were contaminated with the sameCampylobacterspecies as identified in the corresponding flock before slaughter. As tested by PCR, out of the 77 crops withC. jejuni58 were positive for the same bacterial species. On the other hand, out of the remaining 35 flocks infected withC. coli, only 19 corresponding carcass samples were contaminated withC. coli. In three cases in the slaughtered flocksC. jejuniwas identified but in the same carcassesC. coliwas found. The opposite findings (flock positive forC. colibut the corresponding carcasses contaminated withC. jejuni) were seen in six voivodeships. It was also observed that several carcass samples were negative forC. jejuniandC. colialthough the original flocks wereCampylobacter-positive before slaughter (total 36 of the 77 samples; 46.7%). On the other hand, some carcasses were contaminated withCampylobacteralthough the flocks were negative for these bacteria (9 samples; 11.7%) which may also be due to internal contamination during slaughter of broilers. |
