Keeping “Bag” Lunches Safe
by: U.S. Department of Agriculture

With school back in session this August, it is important that we keep “bag” lunches safe. Food brought from home can be kept safe if it is first handled and cooked safely. Perishable food must be kept cold. Why keep food cold? Harmful bacteria multiply rapidly in the “Danger Zone” — the temperatures between 40 and 140 °F. Here are safe handling recommendations to prevent foodborne illness from “bag” lunches.

Begin with Safe Food- Perishable food, such as raw or cooked meat and poultry, must be kept cold or frozen at the store and at home. Food should not be left out at room temperature more than 2 hours (1 hour if the temperature is above 90 °F).Prepackaged combos that contain luncheon meats along with crackers, cheese, and condiments must also be kept refrigerated. This includes luncheon meats and smoked ham which are cured or contain preservatives.

Keep Everything Clean- Wash your hands before you prepare or eat food. Wash cutting boards, dishes, utensils, and countertops with hot, soapy water after preparing each food item and before you go on to the next item. A solution of 1 tablespoon of unscented, liquid chlorine bleach in 1 gallon of water may be used to sanitize surfaces and utensils.

Don’t Cross-Contaminate- Harmful bacteria can spread throughout the kitchen and get onto cutting boards, utensils, and countertops. Always use a clean cutting board. When using a cutting board for food that will not be cooked, such as bread, lettuce, and tomatoes, be sure to wash the board after using it to cut raw meat and poultry. Use one cutting board for fresh produce and a separate one for meat and poultry. At lunchtime, discard all used food packaging and paper bags. Do not reuse packaging because it could contaminate other food and cause foodborne illness.

Packing Lunches- Pack just the amount of perishable food that can be eaten at lunch. That way, there won’t be a problem about the storage or safety of leftovers. It’s fine to prepare the food the night before and store the packed lunch in the refrigerator. Freezing sandwiches helps them stay cold. However, for best quality, don’t freeze sandwiches containing mayonnaise, lettuce, or tomatoes. Add these later. Insulated, soft-sided lunch boxes or bags are best for keeping food cold, but metal or plastic lunch boxes and paper bags can also be used. If using paper lunch bags, create layers by double bagging to help insulate the food. An ice source should be packed with perishable food in any type of lunch bag or box.

Keeping Cold Lunches Cold- Prepare cooked food, such as turkey, ham, chicken, and vegetable or pasta salads, ahead of time to allow for thorough chilling in the refrigerator. Keep cooked food refrigerated until time to leave home.To keep lunches cold away from home, include a small frozen gel pack or frozen juice box. Of course, if there’s a refrigerator available, store perishable items there upon arrival.Some food is safe without a cold source. Items that don’t require refrigeration include fruits, vegetables, hard cheese, canned meat and fish, chips, breads, crackers, peanut butter, jelly, mustard, and pickles.

Keeping Hot Lunches Hot- Use an insulated container to keep food like soup, chili, and stew hot. Fill the container with boiling water, let stand for a few minutes, empty, and then put in the piping hot food. Keep the insulated container closed until lunchtime to keep the food hot — 140 °F or above.

Microwave Cooking/Reheating-When using the microwave oven to reheat lunches, cover food to hold in moisture and promote safe, even heating. Reheat leftovers to at least 165 °F.
