How To Tell If Your Canned Food Is Spoiled

How To Tell If Your Canned Food Is Spoiled

Jul 17, 2022Aman Singh

How do you know if your canned food has gone bad? Canned food can spoil due to many factors other than time spent on the shelf. Many canned foods are vacuum-sealed to maintain freshness. If the lid seems to be loose, or if you notice moisture, the food may have gone wrong. To avoid making yourself sick with canned foods that have spoiled, watch out for these signs of a spoiled product:

  • Food that looks mushy, moldy, or cloudy
  • Food that gives off an unpleasant odor when you open the jar
  • A can or lid that shows signs of corrosion
  • A bulging can or lid, or a broken seal
  • Food that has oozed or seeped under the jar’s lid
  • Gassiness, indicated by tiny bubbles moving upward in the jar (or bubbles visible when you open the can)
  • Bubbles usually indicate fermentation, a bacterial process that can be perfectly fine if done deliberately and under certain conditions. It’s also great for pickles, wine, beer, and other dishes. 

Canned food is generally safe and can last a long time on the shelf! Unfortunately there are many factors that can cause the food to go bad quick so just be sure to double check this list before eating something that has been stored for a while. You don’t want to risk getting sick because of bacteria.
