An estimated 1.4 million cases of salmonellosis occur annually in the United States. To better understand Salmonella disease trends it is important to distinguish between cases attributable to foreign travel and outbreaks from those which are sporadic. Since 1998 the NYS Department of Health Emerging Infections Program’s (EIP) Foodborne Disease Active Surveillance Network (FoodNet), conducted active laboratory-based surveillance for specific foodborne pathogens in three major metropolitan areas of the state. Sporadic cases were defined as cases with no history of foreign travel or association with a known outbreak. Rates were calculated using intercensal estimates from 1998-1999 and 2000 census data for 2000 – 2002. Between 1998 – 2002, NYS FoodNet reported 1521 Salmonella cases with an average annual incidence of 14.5 cases /100,000 persons. Outbreaks and foreign travel accounted for 18.9% and 7.1% of cases, respectively. Incidence rate variation over time was largely due to outbreaks, with sporadic and travel-related cases remaining relatively stable. Serotype frequency differed comparing travel, outbreak, and sporadic cases. S. Enteriditis and S. Typhimurium were consistently the most common serotypes. Over the five-year period, 7.6% of outbreak, 13% of travel-related, and 21.8% of sporadic cases were hospitalized. Age was not significantly different across the three groups. Collecting data on international travel and outbreak association is an important component of foodborne disease surveillance. An accurate estimate of sporadic illness offers insight into the trends of disease and may be important for identifying problems in food production and distribution.
