Food Safety Report: McDonald's.

My cousin and three kids spent the night at my house on 1-10-15. They had eaten at the McDonalds around 2 pm. Which had terrible service through the drive thru and their food was cold. At midnight they all began vomiting and having diarrhea. They had these symptoms well into the next day, 1-11-15. We attempted to disinfect everything we could so no pathogens affected us. However, my eight year old started vomiting and diarrhea this evening, 1-12-15. | Symptoms: Diarrhea, Nausea, Vomiting
