On the other hand, canned food which has gone bad is quite easy to spot once you know what you are looking for. Below are a few warning signs indicating that your canned food has gone bad.

  • Bulge In The Lid Of The Jar: Canned food containers should not create a bulge as it is an indication of gas being created which is due to the presence of microorganisms, so refrain from eating the contents of such containers.
  • Excessive Pressure Being Released When You Open The Jar: Hearing a slight “whoosh” is fine when opening a sealed container, but a lot of pressure n opening the container is not a good sign as it could be a sign of bacterial activity.
  • Formation Of Bubbles: Bubbles are usually a sign of fermentation, which is great if done on purpose and under specific conditions. However, if it is unintentional, then it’s rare for it to be a good thing, as it can cause deadly problems.
  • Formation of Foam: Foam is an indication of bacterial activity, and dangerous bacteria like Botulism can form and multiply in there.
  • Signs of Mold: Any signs of mold on the underside of a lid mean the food should be discarded, despite the color of the mold.
  • Inadequate Seal: If the container is not safely sealed, then it will increase the chances of the content in the container getting spoiled due to microorganisms.
  • Leakage From The Container: Traces of food on the outside of the container is likely due to a leak in the container from which the content is spilling out. If there’s a leak, then the content is compromised and dangerous to consume.
