Mellow mushroom

I’ve had what appeared to be food poisoning twice after eating at Mellow Mushroom. The first time it was after eating a sandwich, and the second time was after eating pizza. Both times I had nausea, vomiting and diarrhea about 8-10 hours after eating. Haven’t been back since. | Symptoms: Nausea, Diarrhea, Vomiting See Less

I ate it Thursday night and all Friday and all today has been horrendous. I woke up 6 times just to use the restroom. I ordered a create your own with mushroom trio, tempeh, onion and spinach woth an olive oil base. Check your temperatures on food in BOH. I have a feeling it was the mushrooms. | Symptoms: Diarrhea See Less

I had pizza from here The pizza and service was good but today (the day after eating it) I have had really bad diarrhea and nausea and other symptoms so it’s extremely possible that the pizza there has ingredients that may cause food poisoning or other food...

My sister is the only one who hasn’t had diarrhea and she’s the only who didn’t eat pizza. | Symptoms: Nausea, Diarrhea See Less

Hi, Thanks for your comment. It is common to get food poisoning from Pizza. Frozen pizza has been linked to E. coli and restaurant pizza contains high-risk ingredients that can cause food poisoning if mishandled. The main culprit is often raw eggs in undercooked dough, but toppings like meat and cheese can contain Listeria.

Ate a shiitake pizza from there yesterday for a late lunch with my boyfriend and now I’m crapping my brains out and having really intense nausea and lower abdominal pain. I noticed that our waiter seemed a little baked when he was serving us especially due to...
