Abstract

AIM: The purpose of the study is to assess the epidemiological situation of food poisonings and infections in Poland in 2015 MATERIALS AND METHODS: The evaluation was based on the analysis of information sent to Department of Epidemiology NIPH-NIH through ROE (Pol. Rejestr Ognisk Epidemicznych)- (an electronic system created for uploading, transfer and analysis of data acquired during the outbreak investigations). Additional sources for the analysis were NIZP-PZH annual bulletins (Czarkowski MP et al. “Infectious diseases and poisonings in Poland”, 2007-2015. Warsaw, NIPH-NIH and GIS) RESULTS: In 2015 a total number of 560 foodborne infections and intoxications outbreaks were reported in which 21 962 persons were exposed and 7 037 (including 1 896 children up to 14 years of age) got sick. Hospitalization was required for 1 905 of patients. The most frequent etiological agent was Salmonella sp. – 34.3%, and 21.4 % of cases).
