Portabella Mushroom Illness - H-E-B, League City Texas

2755 East League City Parkway, League City, 77573 Texas, United States

Purchased Portabella mushrooms on 2/7/23. Kept in refrigerator. Cooked until caramelized. No slime or discoloration noted.
About an hour after eating I had nausea, gastric distress, and diarrhea.

No "sell by" or "use by" on label. Sold by HEB Organics and grown in Madisonville.

02/13 update: I'm fine. Fortunately I cooked the mushroom very thoroughly, which reduces the amount of poison. | Symptoms: Diarrhea, Nausea, Gas
