The short answer

Why Fire Makes Food Unsafe

High heat from a fire can cook or spoil food even if the package looks fine. Canned goods can burst or develop harmful bacteria if heated. The temperature inside a home during a fire often exceeds safe storage levels, so food that was not directly burned may still be compromised.

Smoke and soot can seep through tiny gaps in packaging, cardboard, plastic wrap, and even sealed containers. These particles contain chemicals that are not safe to eat. Even if food looks and smells normal, you cannot always see or taste the contamination.

Which Foods to Throw Away

Throw out all perishable foods like meat, dairy, eggs, and leftovers that were in the house during the fire. Also discard any food stored in cardboard, paper, or cloth, because those materials absorb smoke. Canned goods and bottled drinks should be thrown away if the can or bottle shows any signs of heat damage, such as swelling, rust, or leakage.

Foods in sealed glass jars may be safe if the jar is intact and the lid is still tight, but you must wash the outside thoroughly with soap and water before opening. Even then, inspect the food for any off odor or color. If you have any doubt, discard it.

  • Perishable items: meat, poultry, fish, eggs, dairy
  • Any food in cardboard, paper, or cloth packaging
  • Cans that are swollen, dented, or leaking
  • Bottles with damaged or loose caps
  • Food stored near the fire or in high heat zones
  • Any item with a smoky smell or visible soot

What About the Pantry and Freezer

Pantry items like flour, sugar, spices, and dry goods should be thrown out if they were exposed to smoke. Even if the packaging looks sealed, smoke can penetrate. The same applies to food in the freezer if the power was out for more than a few hours; check for ice crystals and temperature.

If the freezer stayed closed and food is still frozen solid, it may be safe, but you must clean the exterior and check for any smoke odor. If the power went out, the food may have thawed and refrozen, which can promote bacterial growth. When in doubt, discard.

Cleaning and Salvaging Items

For items you consider salvaging, such as sealed glass jars or unopened cans, wash the outside with a mild detergent and warm water. Then rinse with clean water and dry. This removes surface soot and reduces the risk of transferring contaminants when you open the container.

Never use bleach on food containers, as it can leave harmful residue. After cleaning, transfer the contents to a clean container before eating. However, remember that heat may have already spoiled the food inside, so always check for signs of spoilage like bulging, off smell, or unusual texture.

When to Consult a Professional

Food safety after a fire can be complex, especially if the fire was extensive or involved chemicals. Local health departments or food safety experts can provide guidance specific to your situation. If you feel unwell after eating any salvaged food, see a doctor immediately.

Fire damage also affects your home's structure and air quality. For water damage that often accompanies firefighting efforts, consider a professional water damage inspection to assess hidden moisture. In Frisco, you can find local services for structural drying and moisture mapping to help restore your home safely.

Frequently asked questions

Can I wash soot off food and eat it?

No. Washing the outside of a package does not remove smoke that has penetrated the food itself. Soot and chemicals can seep into porous packaging. Throw away any food that has visible soot or a smoky smell, even if you wipe it off.

Is food in a sealed can safe if the can is not damaged?

Maybe, but only if the can shows no signs of heat damage, like swelling or rust. High heat can cause bacteria to grow inside. If the can is intact and you clean the outside, the food inside may be safe, but check for off odors and colors before eating.

What should I do with food that was in the freezer during a fire?

If the freezer was closed and the power stayed on, the food may be safe. But if the power went out, the food may have thawed and refrozen, which can cause bacteria. Discard any food that is no longer frozen solid or has an off smell.
