My wife and I went for lunch on Wed. 12/5/18 as we usually do at the Burger King at 10th st. & Mulvane in Topeka, Ks and ordered a two separate meal, a whopper and a chicken meal. Immediately afterwards we developed stomach cramps and diarrhea,

Possibly wasn't cooked all the way, lunch has a severely high volume on customers. So they might been overwhelmed. Sorry on behalf of my Bk if it was our food that got you and your wife sick. I would take it up with corporate. Which you can find the number on the back of any bk receipt.
