Abstract
Salmonellosis is one of the most important food-borne zoonoses, and the main sources of infection for humans are contaminated meat and poultry meat products. During the five- year period from 2016 to 2020, 2457 samples of poultry meat were tested for the presence of Salmonella spp. Samples were obtained from slaughterhouses and butcher shops in five counties: Međimurje, Varaždin, Koprivnica- Križevci, Bjelovar-Bilogora and Zagreb. Salmonella spp. was isolated from 136 (5.5%) pro- cessed samples during the study. In 2016, it was isolated in 5 (6%) of the tested samples, in 2017 in 41 (4.7%) samples, in 2018 in 33 (6.1%) samples, in 2019 in 26 (6.6%) samples, and in 2020 in 31 (5.4%) samples. The most common identified serovar was S. Infantis in 86 (63.2%) isolates, followed by S. Typhimurium in 8 (5.9%) isolates, and S. Enteritidis in 3 (2.2%) isolates. The following salmonella serovars were also identified: S. Corvallis - 5 isolates (3.7%), S. Isaszeg - 5 isolates (3.7%), S. Derby 3 isolates (2.2%), S. Give - 2 isolates (2.2%), S. Indiana - 2 isolates (2.2%), and 1 isolate each of 7 (5.1%) serovars (S. Schwarzengrud, S. Goldcoast, S. Chester, S. Bredeney, S. Mbandaka, S. Newport, S. Saintpaul). No identification was confirmed in 15 (11%) isolates. S. Infantis was the most common serovar during the study period. Salmonellosis is a significant economic problem due to damages in intensive produc- tion, but also as a zoonosis that can spread to humans through meat and poultry meat prod- ucts. In identified isolates of Salmonella spp., the serovar S. Infantis dominated in chicken meat, which has been confirmed in earlierresearch in Croatia and other EU countries. Implementing appropriate hygiene measures and good hygiene practices from poultry farms and slaughterhouses to shops could contribute to lower contamination of chicken meat with different serovars of Salmonella spp.
