Scenario 1

Jeremiah went grocery shopping on a hot summer day. He bought the following food for an upcoming family BBQ; ground beef for hamburgers, a couple of steaks, and the ingredients for making potato salad.

When he left the store, he put his groceries in the trunk and stopped by the sports outlet store to pick up a Frisbee and croquet set. It took about 10 minutes at the sports store, and then Jeremiah headed home to prepare the food. He was concerned that it had been too hot in the car, but everything was still cold when he got home. Jeremiah put everything in the refrigerator. The meat fit well on the top shelf, right above the potato salad ingredients.

Later on, he got the groceries out to prep everything for the BBQ. He cooked the potatoes and used a sharp knife to trim some excess fat off of the raw steaks. Then he cut up the rest of the vegetables for the potato salad with the sharp knife on a cutting board.

Jeremiah formed the hamburger patties, seasoned the steaks, and finished making the potato salad. With only about 45 minutes to go before leaving for the BBQ, Jeremiah left everything sitting out on the counter while he showered and got ready.

When he arrived at the BBQ, he set the potato salad on the picnic table and went to grill the steaks and burgers. He cooked both to about medium doneness, meaning both were pink in the middle.

Jeremiah enjoyed one of the steaks he prepared and gave one to his cousin. The other family members enjoyed the burgers and potato salad. Jeremiah didn't have a chance to try the salad. A couple of days after the BBQ, Jeremiah learned that everyone at the BBQ, with exception of himself and his cousin, experienced a bout of flu-like symptoms the following day.
