I'm not sure but I have had diarrhea with extreme cramping two or three days not consecutive over this past week Monday and Wednesday I had extreme cramping and diarrhea. I'm not completely sure what may have caused this but I have eaten frozen chicken patties from Tyson. Potatoes, romainelettuce, apples and another restaurant in the past few days (that I can remember). The symptoms came on quick and we're gone by morning. I'm the only one who has gotten sick.
