We aren't sure if it was raw oysters or a deli sandwich. Either from a buffet or a caterer in Michigan. 8 people went to a buffet . Only one got sick. He got sick 36 hours after eating at the buffet. He had raw oysters there. He also ate a deli sandwich that he thought tasted strange on New Years Eve. The symptoms started at 6am on 1/1/19. We ate at the buffet on 12/30/18 at 6pm. He ate the sandwich around 1am on 1/1/19. | Symptoms: Diarrhea, Fever, Nausea, Vomiting
