I bought and ate and served others the Costco Lasagna (2-pack). I cooked it in the oven per the directions. I was sick to my stomach that evening (foul gas). I reheated it from the refrigerator the next day, and gave a portion to my father and we both got sick to our stomachs and had diarrhea.  | Symptoms: Diarrhea, Stomach Pain, Gas

I ate a hot dog and the condiments were broken and as I still squeezed some out I ate the hot dog with all condiments. Less than an hour later, I experienced severe stomach ache and diarrhea 3 times the past 4 hours.  | Symptoms: Diarrhea

Ate a bowl of family size original Cheerios cereal (heart-shaped) from Costco (best by Dec 17, 2025) with milk. Noticed gas-like sounds coming from my belly immediately after finishing the bowl. Within half an hour I had stomach upset and diarrhea. Thought it could be the milk… See more
