Sponges are great places for bacteria to breed. While most of the 362 types of bacteria that can be found on a sponge won't hurt you, according to the UK's National Health Service, it's always a good thing to sanitize sponges regularly.
Like many people, you probably don't clean your can opener after every use. You should probably change that habit.
Can openers can harbor yeast, mold, salmonella, E. coli.

Have you ever thought about how often you clean your oven mitts? I know some people that never wash theirs.

Cleaning oven mitts
Toss your oven mitts in the washer once a week or sooner if they've touched raw foods. Make sure you put them in the dryer too, but only if the material they are made of can survive it. The heat will kill any remaining bacteria.
To get the blade area extra clean, twist off the base of the container. Take apart the blade and rubber gasket and scrub them down with warm water. Let them completely air dry before you put the blender back together.
