An outbreak of gastroenteritis occurred among attendees of a church picnic in Kerr County, Texas. From the cohort study, the bean dish was most strongly associated with illness, however the barbeque chicken, and barbecue sauce were also associated with illness. The barbeque chicken and corn on the cob tested positive for Salmonella. PCR was used to screen food items for Salmonella. Using this technique Salmonella was detected in the chicken, but not in other food items. The PCR results were consistent with culture results. The cooked beans may have become cross contaminated by uncooked or undercooked chicken. The bacteria on the corn likely got there during serving of the food and did not reach levels high enough to cause illness by the time that the guests ate their food.
