The COVID-19 pandemic and the associated restrictions introduced in the country, as well as increased hygiene through more frequent washing and disinfection of hands, could have contributed to a reduction of almost 69% in the number of salmonellosis cases registered in 2020, in Poland, compared to 2019. This is a 82% decrease in relation to 2018. There was also a decrease in the number of food poisoning outbreaks caused by Salmonella bacilli, while at the same time their percentage in the total number of outbreaks increased. On the one hand, the implemented restrictions could have had an impact on the decrease in the number of cases and outbreaks, on the other hand, worse access to medical care and diagnostics, most likely deepened the underestimation of these cases in the country observed for years, and distorted the real picture of the situation.
