4. Vermin
Everything that’s been on the floor of a shop or a factory is at risk of being exposed to vermin like mice and rats. Usually, food is protected enough by its wrapping to ensure vermin can’t get in. However, when drinking from a can, you are drinking from the place vermin can get to! If you believe the horror stories on the internet, you can die from consuming rat urine. Even though that’s probably an exaggeration, we don’t think it’s very pleasant to drink from a can that has possible urine or faeces on it. We recommend rinsing the can before drinking from it.
