Here’s When You Shouldn’t Use Aluminum Foil for Leftovers (2024)

Refrigerated leftovers typically last up to four days if leftovers are sealed and stored correctly. For most people, covering a plate with foil and tossing it in the fridge is a quick, easy way to store food. However, wrapping your food in a sheet of aluminum foil is also an easy way to put yourself at risk for health hazards.

Why you shouldn’t use aluminum foil for leftovers

Much like we need air to breathe, bacteria need air to thrive. Some bacteria like staph and Bacillus cereus, which cause foodborne illnesses, produce toxins that aren’t destroyed by high cooking temperatures. When a hot meal is left out at room temperature for more than two hours, the bacteria grow rapidly, according to the Washington State Department of Health.

Using aluminum foil to cover food poses the same risk since it doesn’t completely seal your food off from the air. “When air is present, that allows the bacteria to grow faster, so you really want to get the right containers and pack things appropriately,” says Lindsay Malone, a registered dietitian at the Cleveland Clinic. “Otherwise, your food isn’t going to last.”

How should you package leftovers?

If you are saving those leftovers, here are some food storage guidelines to package them safely:

  • Always seal them in shallow, air-tight containers to speed up the cooling process and keep bacteria off of your food.
  • Make sure you put the food in the fridge within two hours, before the bacteria has time to wreak havoc on it. Dairy and meat products are especially prone to bacteria growth, which reiterates just how important it is to use air-tight containers for any and all leftovers.
  • Throw away any food that has been sitting out longer than two hours
  • Be aware of the foods you shouldn’t put in the refrigerator.

“If you have an abundance of food left over, the smartest thing to do would be to put a portion of it in the refrigerator, and then pack a portion of it really nice in air-tight containers and put it into the freezer,” says Malone. “And then when you’re ready to eat it, take it out.”

What to use to store leftovers safely

Storing leftovers safely means finding air-tight seals for your leftovers. Better yet, opting for eco-friendlier reusable containers made from glass, food-grade silicone, and multiple-use BPA-free plastics. These can save you cash in addition to saving your leftovers from spoiling.
