Cheese Sauce Causes Illness - Burger King, Hallstadt Bayern

36 Biegenhofstraße, Hallstadt, 96103 Bayern, Germany

I ordered 2 chilli cheese burgers that didn't have jalapeno on them. After we announced it, they asked for a receipt and only after a great discussion did we get 2 new ones.
The cheese sauce tasted sour. About 1 hour later I had severe abdominal cramps as well as diarrhea and headaches since yesterday evening. I'm expecting food poisoning. The sauces are probably old and rotten forever. | Symptoms: Nausea, Diarrhea, Headache
