Why shouldn't you buy dented cans?

Answer 1

You may be infected with botchulism. Botchulism is food poisoning that one may get from eating food out of a damaged can.

The issue of dented cans goes back many years to the original idea. The concept was that a can kept food fresh as the can was airtight. However, in recent years (about 25) it was discovered that the weld on the sides of cans were made of a lead based solder. If the can became damaged particles of the solder entered the cans content and of course this was ingested by the users. This gave rise to lead poisoning at the very worst or high levels of lead in the blood at the very least. Manufacturers were forced by law to make changes to the sealing compounds used. This issue of denting as already stated gave rise to questions on the quality of the product in the can and the chances of cross contamination. Retailers and manufacturers do claim that dented tins are not an issue, these are just very unsightly. However, punctured containers are and should not be used as the contents have been exposed to the sir and the condition of that product is reduced substantial.
