Answer:
Discard the cans.
Explanation:
You must discard the cans if you can lay your finger in the dent, that's too deep. It's better to be safe and discard or return the can. Swollen cans often indicate a spoiled product. During spoilage, cans may progress from normal to flipper, to springer, to soft swell, to hard swell. However, spoilage is not the only cause of abnormal cans. Overfilling, buckling, denting, or closing while cool may also be responsible.
It can cause difficulty breathing, muscle paralysis, and even death. The toxin is made most often by Clostridium botulinum bacteria. Improperly canned, preserved, or fermented foods can provide the right conditions for the bacteria to make the toxin.
