Meatballs Cause Illness - Hello Fresh, Bünde North Rhine-Westphalia

Bünde, North Rhine-Westphalia, Germany

My girlfriend and I wanted to cook something out of the HelloFresh box together after work.
It also tasted really good, only in the night we both started nausea and diarrhea. In addition, I had vomiting in the morning. So far, it's been going on for 3 days, my girlfriend didn't get it that bad.
Meatballs were cooked, pork and beef and confetti mash (potatoes and carrots) in mushroom cream sauce. | Symptoms: Nausea, Diarrhea, Vomiting
