(KAIT/NBC) - Many of us don't think of taking our shoes off when we walk inside the house. Is there any real harm in keeping them on?

Dr. Kevin Garey from the University of Houston started testing the shoes and homes of his own students their friends.

He found the majority of tests had relatively harmless germs.

However, a significant number of them were walking around with the bacteria C. diff.

"When you are at risk, you should be aware of this. If you're elderly, if you've recently been hospitalized, and this would be something when you go home, let's clean the house really good because I have an at-risk person coming to the home," said Dr. Garey.

Dr. Garey said places in homes that are most likely to be contaminated are doorsteps and high traffic areas.

He suggests normal cleaning or the removal shoes before you visit a vulnerable person.
