Start at the Store: 7 Ways to Prevent Foodborne Illness

7. Be mindful of time and temperature.

It's important to refrigerate perishable products as soon as possible after grocery shopping. Food safety experts stress the "2-hour rule"-because harmful bacteria can multiply in the "danger zone" (between 40° and 140° F), perishable foods should not be left at room temperature longer than 2 hours. Modify that rule to 1 hour when temperatures are above 90° F, as they often are in cars that have been parked in the sun.

If it will take more than an hour to get your groceries home, use an ice chest to keep frozen and perishable foods cold. Also, when the weather is warm and you are using your car's air conditioner, keep your groceries in the passenger compartment, not the trunk.
