A Few Hours After a Dinner Party, Most of the People

question 54

Short Answer

A few hours after a dinner party, most of the people who attended begin to suffer nausea, vomiting, and diarrhea. The food at the meal is suspected as the source, although no unusual microbes are cultured from samples of the food or from stool samples. These observations suggest they may be suffering from food (infection/intoxication).
