We have created a tool that provides an estimate of the background exposure rates for particular food items or other exposures. These frequencies are based on data from sporadic E. coli O157 cases that occurred in Minnesota during 2009 – 2013. FoodNet Population Survey estimates from Minnesota are also provided. Epidemiologists can use these frequencies in a binomial model comparison to quickly assess a potential vehicle in a cluster/outbreak investigation. Gender, age, and seasonal frequencies are also provided.
