Abstract
In this study, we investigated cross-contamination with ESBL-producing Enterobacteriaceae during the processing of two different broiler flocks in one slaughterhouse. The ESBL-status during the fattening period of the flocks was determined and environmental samples from the slaughterhouse were taken before processing of the respective flocks. These isolates were compared to those found in samples from the carcasses after processing using whole genome sequencing. Phylogenetic analyses of seven ESBL-producing K. pneumoniae and 14 E. coli revealed close relationships between isolates from scalding water and the defeathering machine, respectively, which were collected before the processing of the broiler flocks, to those isolates found in samples from skin and filet of the respective flock carcasses. In conclusion, using high resolution molecular data we found evidence for the cross-contamination of carcasses with ESBL-producing Enterobacteriaceae during scalding and defeathering in the slaughterhouse.
