Beware of the dent in the can

If so, then your life may be in danger.  This is because canned goods are not immune to spore-forming thermal resistant micro-organisms that can cause botulism - a paralytic illness that can lead to respiratory failure in extreme cases. The toxin spreads very quickly through the body and can cause life-threatening complications if treatment is not administered immediately.

Food items with low pH (acid) levels, like fruit, vegetables, meat and dairy products, are canned in airtight containers to preserve them and prevent proliferation of bacteria. Cans have a thin membrane lining on the inside to keep air and bacteria out. However once dented, there is no guarantee that the membrane is still intact. If the membrane is broken, rust and bacteria will build up. Some bacteria, such as the ones  that caused botulism may be life threatening. Consuming food from a dented can or a broken container may lead to health problems that can cause death.
