Table 10 FoodNet–Overall Change and 95% CI in Incidence of Laboratory–Confirmed Infections 2012

Overall change* (and 95% confidence interval) in incidence of laboratory-confirmed bacterial infections in 2012§ compared with average annual incidence for 1996–1998 and for 2006–2008, Foodborne Diseases Active Surveillance Network (FoodNet), United States
Year 1996–1998 comparison period
% change* (95% CI)
2006–2008 comparison period
% change* (95% CI)
2012 22%↓ (11%↓ – 32%↓) 6%↑ (5%↓ – 17%↑)

*Overall change reported as increase (↑) or as decrease (↓).This measure does not allow for assessment of changes in infections of individual pathogens.
The measure of overall trends in incidence combines data for Campylobacter, Listeria, Salmonella, STEC O157, Vibrio, and Yersinia, the six key bacterial pathogens for which >50% of illnesses are estimated to be transmitted by food. The model weights by incidence of infection for each pathogen.
