I understand that improper food handling piror to the canning process can allow bacteria to thrive once sealed, and that if a food container is punctured then of course any nasties can seep in due to there no longer being a barrier – but why does a deep dent also seem to carry as much risk as the can actually being punctured? Never understood this.
In: Biology
a deep dent most likely means the can is cracked/has been punctured, hence is no longer a safe seal.
basically any can that looks to be significantly physically damaged shouldn’t be presumed to be safe.
