Keeping “Bag” Lunches Safe
by: U.S. Department of Agriculture
With school back in s ession
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.
