Burger Meal Causes Illness - Dairy Queen,

Ordered a hunger buster jr with cheese medium fry and coke. I will admit that I was in a hurry and when I got to work I ate and went back to my day, 5 hours later I had cramping and diarrhea cold sweats and nausea. I only ate that burger since 9am and I'm sure it's food poisoning | Symptoms: Diarrhea, Nausea, Cramps, Sweating
