Extended spectrum β‐lactamase producing Escherichia coli (ESBL‐EC) was detected in 86.6% of chicken and 22.6% of bulk tank milk (BTM) samples. Pulsed‐field gel electrophoresis analysis revealed 49 distinct restriction profiles among 66 isolates, and 62.3% of the isolates carried the blaCTX‐M gene, among which CTX‐M‐1 was found to be the predominant ESBL types in chicken isolates, whereas CTX‐M‐15 was the commonest among BTM samples. Additionally, of 52 ESBL‐EC isolates from chicken meat samples, 36.5%, 9.6%, and 7.7% harbored the blaTEM, blaCMY‐2, and blaSHV‐12 genes, respectively, compared with 28.5% of the blaTEM and 7.1% of the blaSHV‐12 markers among BTM isolates. The fimH gene was present in 51 isolates of chicken and in 14 isolates of BTM samples, while other virulence genes iutA (n = 31), iroN (n = 26), kpsMT II (n = 5), papC (n = 2), papG allele II (n = 2), papG allele II‐III (n = 2), and papEF (n = 2) were only present in chicken meat isolates. Overall, it can be said that contaminated chicken meat and BTM might serve as vehicles for playing potential role in zoonotic transmission of ESBL‐EC to humans in Turkey.
