Vomiting.. Diarrhea etc. yo plait refuses to answer I purchased yoplait yogurt for our battered women facility, the corners were smashed. We debated as to whether we should eat it. Decided I would eat it, because I had not eaten in 4 days. I ate the vogurt. In approximately 40 minutes I began to vomit. The other girls there, began grabbing pans to vomit in. The other ladies got cool cloths. About an hour later, I developed a temperature. I went to bed. I tried and tried to contact yoplait no avail. Ill keep trying M User's recommendation: If you don’t want food poisoning.. do not eat.
