The paper presents results of the Salmonella identifcation, testings of recovered isolates for their susceptibility to antibiotics and their serogroup and serovar distribution. In 2012–2017 13,774 tests of animal products were performed, 105 Salmonella contaminated samples were detected which is 0.76% of the total number of the tested samples. As a result, 31 isolates were recovered. It was established that 22 of them belonged to seven serovars: S. enteritidis, S. infantis, S. nigeria, S. montevideo, S. typhimurium, S. derby, S. meleagridis. S. infantis (38.7%) and S. enteritidis (16.1%) were identifed as the most spread serovars. There was observed a trend of increase in contaminated samples: 1.13% in 2012 upto 2.84% in 2017. The performed tests for antimicrobial resistance demonstrated that all isolates were susceptible to the following antibiotics: carbpenemes (meropenem, imipenem), β-lactams (amoxicillin /clavulanate), aminoglycoside (amikacin, gentamycine), macrolides (azithromycin). Most of the isolates demonstrated susceptibility to β-lactam antibiotics (ceftriaxone, cefotaxime), fluoroquinolones (ciprofloxacin) and aminoglycosides (kanamycin). Resistance at least to one antibiotic was detected in 12.9% (4/31) of isolates. Resistance to at least three antibiotics was detected in 6.5% (2/31) of isolates. 58.1% (18/31) of isolates demonstrated multiple resistance (to four or more antibiotics).
