“In the United States, about 110 cases of botulism are reported each year“. A person can’t see or smell if a can is contaminated with botulism spores, however, there are other contaminates that can be seen and smelled. The good news is that most of the signs that canned food has spoiled are fairly easy to recognize once you know what to look for. Below is a quick review of what to keep an eye out for. See if you know all the signs to watch out for.
1. A Lid that Bulges Moving Up & Down
This unsafe can of whole potatoes had been exposed to extremely cold temperatures and relatively hot temperatures in my garage, over a 6 month period.
2. Food Projecting or Exploding When Opened
3. Rusting / Corrosion of Can
This was pulled out of a house fire and it was covered with soot. Soot and moisture corrodes metal. Corrosion will eventually create holes that let in air and bacteria.
