Molecular Characteristics of Epidemiologically Successful Salmonella Enteritidis in Poland

open access: yesTransboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Since 2014, the long‐term decreasing trend in human salmonellosis, caused mainly by the consumption of Salmonella‐contaminated poultry products, has stagnated in the European Union (EU). As Poland has been the leading poultry meat producer in the EU since 2014, we analysed whole genome sequences of 275 Salmonella (S.) Enteritidis strains from the ...
