If you’ve had a fire in your home—even if it wasn’t in the kitchen—it’s important to know the ins and outs of food safety to make sure you’re not cooking with or eating anything unsafe.

Here are five tips to help:

1. Throw away any and all food near the fire. The heat of the fire itself, smoke fumes, or fire-fighting chemicals can make food unsafe. Even food in cans or jars that look normal can be at risk, because the fire’s heat can activate bacteria that cause spoilage.
2. Trash any raw food or food stored in permeable packaging like cardboard, plastic wrap, and screw-top jars, which can be contaminated from a fire’s toxic fumes.
3. Discard any food exposed to fire-fighting chemicals. These chemicals cannot safely be washed off food, not even fresh produce.
4. Carefully consider the location and size of the fire relative to your refrigerator. Your seal is not airtight, and deadly fumes can get inside and contaminate food. When in doubt, throw it out.
5. If your cookware and dishes were exposed to fire-fighting chemicals, you can wash them in soap and hot water, then submerge them in bleach water for 15 minutes. Use a solution of 1 tablespoon of unscented liquid chlorine bleach per gallon of water.
