On 3/30 went to Panera bread. I had a tuna sandwich with only lettuce and white cheddar cheese. Had severe abdominal cramping and diarrhea for the next two days. I wasn't sure if it was panera because the day before I ate taco bell which can give you a toxic swell. However after going to panera again on 4/12 and again having a tuna sandwich with only lettuce and white cheddar, within the hour after eating panera the exact same symptoms of abdominal cramping and diarrhea. I reported to “iwaspoisoned.com” which says they also report info to cdc etc... wont be eating at panera for a long long long time if ever again.
