Canned food safety during the heat wave?


Thank you for your question. I hope you are managing to stay cool during this hot weather!

Temperatures over 100º F are harmful to canned foods, and the risk of spoilage jumps sharply as storage temperatures rise. The thermophilic, or heating-triggered, pathogens vary from product to product and are unpredictable.

I would recommend caution with any canned foods that have been exposed to high heat. The longer and higher the heat was will increase the likelihood of spoilage. Not all harmful pathogens, including botulism, give off gas to create pressure inside a can or jar so that is not always a reliable sign of spoilage.

These cans could be a food safety risk.
