Guests who ate the famous baked potato salad called to complain of nausea and vomiting. These calls began within 2 days after eating the dish. The guests eventually also experienced double vision and difficulty in speaking and swallowing. The local regulatory authority investigated. They found that the baked potatoes in the salad were the source of the outbreak. The potatoes have been wrapped in aluminum foil when they were baked. Then they were left on a prep table overnight to cool. Ultimately, the potatoes were left at room temperature for almost 18 hours before they were used in the salad. Bacteria on the potatoes had the correct conditions for growth. These conditions included time, temperature, and a lack of oxygen provided by the potatoes' foil wrapping.

What could have been done to prevent the outbreak?
