An outbreak of gastroenteritis due to Salmonella Enteritidis associated with an outdoor public holiday event occurred in a small village in southern Latvia on 21 July 2006. The outbreak lasted from 22-25 July. Descriptive and analytical epidemiological investigations were conducted to determine the extent of the outbreak, and to identify outbreak-related risk factors. Of approximately 260 people who attended the event, 107 participants were interviewed and 49 people fulfilled the criteria of an outbreak case (attack rate 46%). Stool specimens from 26 people including 17 kitchen workers, were microbiologically tested, and eight specimens were found to be positive for S. Enteritidis. The retrospective cohort study revealed that a fried pork dish made with raw egg was the likely cause of the outbreak (RR: 7.8, 95% CI 5.2-11.78; P=<0.001). (Extrait)
