In the Bryn Du event, put on by the Columbus Museum of Art and catered by Sidecar Global Catering, of Columbus, 41 of 78 people in attendance experienced a gastrointestinal illness. Most were from Franklin County.
Based on interviews with several people who attended the Bryn Du event, the health department thinks a dish served at the event, Spanish peppers with goat cheese, was the source of the virus.
"The assumption is at some point, either in the preparation or the supply chain, the food became contaminated," he said. "There was no cooking process to kill off the virus."
