Foodborne infections and intoxications in Poland in 2012.

AIM: The purpose of the study is to assess the epidemiological situation of foodborne infections and intoxications in Poland in 2012.

MATERIALS AND

METHODS

The evaluation was based on analysis of information from reports of epidemiological investigations in foodborne outbreaks, 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", 2006-2012. Warsaw, NIPH-NIH and CSI).

RESULTS

In Poland in 2012 there was observed decrease in the number of infections intoxications both of bacterial and viral origin. It was recorded only one case of trichinellosis. There were reported 491 outbreaks of foodborne poisonings or infections included 5 774 people, among them 718 children 1-14 years old. Out of them 1 364 people were hospitalized. Unlike last year, the predominant etiological agent in those outbreaks were zoonotic Salmonella serotypes which caused 38.1% outbreaks and 26.7% outbreak cases. The viruses have caused 27.1% of outbreaks and 36.2% of cases. In 23.8% of outbreaks etiological agent has not been established. Most often the settings of an outbreak was a private household - 236 outbreaks and a hospital (84 outbreaks). As in previous years, the most common vehicle of infection were foods prepared with milk and eggs -11.8% of outbreaks and egg dishes - 9.0%. In 57.6% of oubreaks vehicle of infection has not been established. Among outbreaks reported in 2012, there were 4 which involved more than 100 people. In 163 outbreaks of food items had been tested and in 33% of them the results were positive.

CONCLUSIONS

The increasing negative results of bacteriological examinations of food items, suggested necessity to start testing food contamination with viruses.
