Any food, beverages and/or medications exposed to heat or smoke should not be consumed. Medication especially, can change strength by exposure to heat. Please check with your doctor first before taking these medications.
If food was in a tightly closed or sealed container, or in airtight refrigerators or freezers, they may be salvageable. It is cheaper to replace the material than to jeopardize you or your family’s health by taking a chance. If in doubt, throw it out!
