Carnitas Burrito Illness - Chipotle,

My son has a carnitas burrito with white rice, pinto beans, sour cream and lettuce around 6:30pm. He woke up around 2am reporting horrible stomach cramps and headache. 2 hrs later cramps are worse, feeling nausea and he vomited. He feels better now that its all out. | Symptoms: Nausea, Vomiting, Cramps, Headache
