(KFYR) What's green and white and filled with germs? Your cash.

Most people we spoke to said it's not surprising because of how many hands those bills actually go through. Some even admitted that they're not even thinking about it.
"You think about all the hands that it goes into and drops on the ground; picks it up and hands it over to the next person. Money is dirty, very dirty," says Kelli Seideman.
The best advice we can give you, is to wash between paying.
