Big Mac Causes Illness - McDonald's, England

CM77 8EZ England, United Kingdom

Myself and my 2 kids went there at12.30/1pm. I had a Big Mac but they didn't eat same as me. Nausea started 2 hours later. Sickness hit at 4pm through 12am. Had only had Toast that am and nothing after lunch. Children are not sick so can only assume it was the burger | Symptoms: Diarrhea, Nausea, Vomiting, Other
