Item 3 Before a very expensive black-tie gala, the venue for the event lost power for about 3 hours. There was no back- up generator, but the venue manager determined the food would remain safe if they were put on ice. Once power was restored, foods were refrigerated and reheated. Within 1 day of the event, the venue manager received many complaints about guests being ill. The most likely culprit was food poisoning due to unsafe food storage and handling before and during the events. All 550 guests were interviewed, and the following basic information was collected about their meal choices. Many guests would have sampled different foods.
