title: Foodborne infections and intoxications in Poland in 2013.
abstract: OBJECTIVE
  The purpose of the study is to assess the epidemiological situation of food poisonings and infections in Poland in 2013.
  
  
  METHODS
  The evaluation was based on the analysis of information from reports of epidemiological investigations in outbreaks of food poisonings and infections, submitted by the sanitary-epidemiological stations to the Department of Epidemiology, NIZP-PZH annual bulletins (Czarkowski MP et al. "Infectious diseases and poisonings in Poland", 2006-2013. Warsaw, NIPH-NIH and GIS).
  
  
  RESULTS
  In 2013 a further decrease in the number of infections and intoxications with bacterial etiology and an increase in the infections of viral etiology was observed. Furthermore 2013 is another year with low number of cases of trichinellosis (9 cases in total). In 2013 a total number of 491 foodborne infections and intoxications outbreaks were reported in which there were 29,179 persons exposed and 5,664 (including 2 193 children up to 14 years of age) persons ill. Hospitalization was required for 1,445 persons. The most frequent etiological agent in those outbreaks was Salmonella spp.--which was responsible for 36,3% of outbreaks and 21,5% of cases. Viruses were responsible for 29,7 of outbreaks and 45,7 cases, in 19,3% of outbreaks no etiological agent was established. Like in 2012 the most frequent vehicle were dishes made from eggs and milk combined with eggs (9,4% of outbreaks). In 65% of outbreaks reported no vehicle could be found. Moreover in 2013 a total number of 3 outbreaks in which more than 100 cases were reported.
  
  
  CONCLUSIONS
  The increase in the number of foodborne outbreaks of viral etiology shows the need of adjustment some aspects of epidemiological investigations especially such features as: laboratory conformation of etiological agent of ill persons as well as persons involved in the food processing and meals preparing and the aspect of food samples testing.
