Why is it considered safe to only boil drinking water yet not sterilize canned food?

This happens when there is a water pipe leak in the area. During the repair work, a section of the water pipe becomes contaminated with the bacteria commonly found in the soil. When this occurs, the water company is required to post boil water advisories in the area and on the local news to keep bacterial illnesses to a minimum. The water may even be tainted or dingy after a leak, but after boiling, it is safe to drink because the boiling temperature kills all the bacteria that may be found in it. Canned food is sterilized when it was canned so it needs to special sterilization steps to eat it. Hooweestik.
