Occurrence and antimicrobial resistance of salmonellae isolated from broiler’s liver and washing water obtained from small-scale poultry processing plants [electronic resource]

Includes bibliographic reference.

In this investigation, fifty-five chicken livers and washing water samples were gathered from
the small-scale poultry processing plants in Cairo and Giza governorate, Egypt. Salmonella
occurrence was detected, identified, and finally phenotypically characterized for the most
common antibiotic groups to detect its antibiotic resistance profiles. Salmonella species have
been recovered from 1 out of 45 (2.2%) examined chicken livers. This isolate was
biochemically identified and molecularly verified such as Salmonella by the invA gene
detection using PCR. The Salmonella serovar was recognized as S. Anatum. The isolated S.
Anatum showed resistance to ten antimicrobial agents among six antimicrobial classes, so this
isolate was classified as MDR. Its resistance was against gentamicin, ampicillin,
ciprofloxacin, tetracycline, chloramphenicol, cefepime, ceftazidime, ceftriaxone, cefotaxime,
and aztreonam. In conclusion, chicken livers were contaminated with MDR Salmonella
serovars, which could be extremely dangerous for human health. To control such food
poisoning hazards, the necessity to implement food safety systems is imperative.
Additionally, continuous updating of the occurrence and antibiotic resistance profile regarding
Salmonella is an important food safety issue.
