Member States. The objectives of the study were to (I) compare the prevalences of AMR in commensal E. coli obtained from caecal samples of organically and conventionally raised Austrian broiler flocks and to (II) analyze their trends from 2010 to 2014 and 2016 in both populations. Levels of multidrug resistance were (III) evaluated in isolates from both broiler populations and (IV) their development was assessed over the same period.

This study focused on the prevalence of antimicrobial resistance in commensal E. coli isolated from caeca of broilers. The epidemiological unit was the flock to ensure that each sample originated from a different unit, independent on the production practice. For each sampled flock, the intestines of 10 broilers were taken at the abattoir, wrapped in a sterile plastic bag, cooled down to 5 °C ± 3 °C and sent to the laboratory in polystyrene boxes with frozen cooling elements. The annual sampling plan specified the number of samples per abattoir and month
