Dale Fremore was back home after spending the day at a picnic where he ate some "spoiled"
potato salad. He developed severe abdominal pain and cramps, vomiting, and diarrhea. After
about ten to twelve episodes of water diarrhea, Mr. Fremore became so pale and weak he could
hardly walk. His wife took him to the hospital where he was diagnosed with severe dehydration
