Not sure Diarrhea and vomiting within an hour of eating. I was only one who ate salad bar. A couple of the grape tomatoes tasted really sour but I had the organic mix lettuce, red/yellow peppers, cucumbers, green olives, zucchini, carrots, cheese, bacon, and ranch dressing. I had to scrape what was left of both containers of ranch to get any and that wasn’t really enough. Kinda strange considering there was a girl who had topped off everything several times but not the ranch.
