It’s In The Bag

An interesting report appears this week in Pediatrics, the journal of the AAP, on the temperature and safety of brown-bagged school lunches prepared at home.

 

The surprising results appear in an  article called:

 

Temperature of Foods Sent by Parents of Preschool-aged Children

Fawaz D. Almansour, MS, Sara J. Sweitzer, PhD, RD, LD, Allison A. Magness, BS,  Eric E. Calloway, BS, Michael R. McAllaster, BS, Cynthia R. Roberts-Gray, PhD, Deanna M. Hoelscher, PhD, RD, LD, CNS, Margaret E. Briley, PhD, RD, LD

 

 

Essentially, researchers tested the temperature of perishable food items brought to school 90 minutes before lunch at 9 central Texas day-care centers, and found the following:

 

  • 39% (n = 276) of the 705 lunches analyzed had no ice packs
  • 45.1% (n = 318) had 1 ice pack
  • 88.2% (n = 622) of lunches were at ambient temperatures
  • Only 1.6% (n = 22) of perishable items (n = 1361) were in the safe temperature zone.
  • Even with multiple ice packs, the majority of lunch items (>90%) were at unsafe temperatures.

 

In the abstract, the authors write:

 

Conclusions: These results provide initial data on how frequently sack lunches sent by parents of preschool-aged children are kept at unsafe temperatures.

Education of parents and the public must be focused on methods of packing lunches that allow the food to remain in the safe temperature zone to prevent foodborne illness.

 

 

While most parents probably believe that including one or more ice packs are enough to keep food at a safe temperature, the evidence suggests otherwise. 

 

Consuming perishable foods that have been allowed to exceed the recommended storage temperature doesn’t necessarily mean your child will get sick, but it can certainly increase the odds.

 

With that in mind, Foodsafety.gov has some tips on how to pack lunches to reduce the chances of sending an out-of-control biological experiment to school with your child.

 

 

Keep School Lunches Safe

As children head back to school this fall, parents and caretakers may wonder, “What’s the most important thing that the kids should take to school with them?” From my perspective as a food safety specialist, I’d recommend an insulated lunch box as the best investment of the school year. For a few dollars, an insulated lunch box can keep children healthy and engaged to learn by protecting them from foodborne illness.

Packing and eating school lunches

If you pack perishable food in an old-fashioned brown paper bag, it can be unsafe to eat by lunchtime. When children are sent home sick or stay home because of illness, it’s difficult for them to succeed in their school work.

 

Insulated lunch boxes help maintain food at a safe temperature until lunchtime. Perishable lunch foods, such as cold cut sandwiches and yogurt, can be left out at room temperature for only 2 hours before they may become unsafe to eat. But, with an insulated lunch box and a chilled freezer gel pack, perishable food can stay cold and safe to eat until lunch.

 

Why keep food cold? Harmful bacteria multiply rapidly in the "Danger Zone" — the temperatures between 40 and 140 °F. So, perishable food transported without a cold source won't stay safe long.

 

Here are some other tips to keep food safe until lunchtime:

  • Clean Hands: Always make sure your hands are clean before preparing lunches. And, make sure your children understand that they need to wash their hands thoroughly before eating lunch or snacks. “Washing hands thoroughly” means using soap and warm water, and rubbing hands for 20 seconds (the time it takes to sing “Happy Birthday” twice). If water is not available, provide moist towelettes or hand sanitizing gels in the lunch box.
  • Freeze your juice box: You can freeze juice boxes and use them as freezer packs. By lunchtime, the juice should be thawed and ready to drink.
  • Hot Foods: To keep hot foods hot, use an insulated bottle like a thermos for foods such as soup, chili, or stew.
  • Non-Perishable Food: Some food is safe without a cold source. Lunch items that don't need to be refrigerated include whole fruits and vegetables, hard cheese, canned meat and fish, chips, breads, crackers, peanut butter, jelly, mustard, and pickles.

If the lunch box comes home with food in it, make sure to throw away any perishable food items, because they have been unrefrigerated too long!

In other words, you might want to reconsider the wisdom of sending that unrefrigerated egg-salad-sandwich in your child’s lunchbox in the middle of August.
