ACCOMAC, Va. (WVEC) – Health officials said there was Salmonella in specimens they collected after dozens of people who attended the Chincoteague Chili Chowder Cook-off got sick.

The event took place on September 30. Results of tests on the specimens came back on October 9.

The Accomack County Health Department and the Foodborne Disease Team from the Virginia Department of Health began investigating an outbreak of gastro-intestinal illnesses that may be related to the cook-off after people began experiencing severe symptoms including dehydration, severe vomiting, and diarrhea.

Investigators still are working to determine what food or food items may have caused the outbreak.

The Accomack County Health Department still is trying to reach the more than 2,000 people from multiple states who attended the cook-off.

Health officials are asking attendees to provide information through the online outbreak survey that will help answer investigation questions. They also want to makes sure that attendees who still are sick contact their primary care provider or go to the emergency room or an urgent care center if their symptoms are severe and their primary care provider is not available.

So far, health officials have heard from more than 350 attendees.
