| Popis: | Extended spectrum beta lactamase forming Escherichia coli is considered a threat in severe clinical cases. Food producing animals and poultry in particular are considered a possible reservoir for distribution of resistant bacteria to humans via meat consumption. Data on the concentration of ESBL- E. coli as a prerequisite for estimating consumer exposure is still limited. To evaluate the amount of ESBL- E. coli present in meat of broilers after slaughtering we sampled pooled caecal contents and pooled neck skin samples as meat surrogate of 30 broiler flocks for commensal and ESBL- E. coli at three German slaughterhouses. Although ESBL- E. coli were present in 90% of the flocks caeca, they only made up a fraction of the total E. coli (mean 7.9 log 10 cfu/g), the ratio varying with a median value of 0.07%. Samples of neck skin were positive for ESBL- E. coli in 93.3% of the flocks. However analyses in neck skin pooled samples, revealed countable ESBL- E. coli in only 32.7% (n = 150) of the samples with concentrations between 1.0 and 3.1 log 10 cfu/g. In conclusion, concentrations of ESBL- E. coli seem to be low in this study, thus indicating a limited impact of broiler meat for ESBL- E. coli transmission to humans via consumption. |
