Lettuce Suspected in Illness - Shake Shack, Boston Massachusetts

322 Washington Street, Boston, 02108 Massachusetts, United States

I had on 12/20/2019. I had a cheeseburger and fries. I’m pretty sure it was the lettuce that did it. I ate around 1 pm and started feeling symptoms at 545. I was nauseous then started vomiting and diarrhea for the next six hours. I wasn’t able to sleep all night but the symptoms stopped. | Symptoms: Diarrhea, Nausea, Vomiting
