Industry insiders have the hard facts about germs you may not know you are being exposed to.
You may be surprised to learn how many germs are lurking on new clothes you are about to try on.
The "Katie" show tested some clothing samples after people tried them on -- looking at total bacteria, coliform and e-coli bacteria.
Dr. Charles Gerba said he was "very surprised" with the number of bacteria found on swimsuits.
The total bacteria level on the sample suits was 9,720,000.
It can cause serious infections, depending on how long you try something on and the condition of your skin.
Experts said bacteria can actually live longer on the plastic strips inside new bathing suits than on the fabric itself.
Doctors suggest getting a pair of "Granny Panties" that you only use when trying on new bathing suits.
Experts also tested the bacteria levels on lingerie.
Some samples had a total bacteria level of 12,000,000.
The lesson is -- don't try it on and wash it before you wear it!
Experts also tested the bacteria levels on new shoes.
The total bacteria level was 45,200 and the E-coli bacteria level was 800.
They suggested someone may have had socks on when they were walking on a bathroom floor before trying on the new shoes.
The bacteria can also be transferred to your hands. Think of how many people carry the shoe that is on display to a salesperson when they request their size.
Here's something to think about when you dine out -- from soda fountains to self-serve frozen yogurt stands to salad bars, you may be picking up a great big side of bacteria along the way.
Expert tested salad bar utensils.
They found some utensils contaminated with e-coli. Experts say not everyone washes their hands.
If you touch the utensils, you could be picking up bacteria.
Experts suggest using a napkin to hold the serving pieces when you are at a buffet or salad bar.
Another suggestion is to wash your hands after you get your plate.
They also tested the bacteria levels in frozen yogurt and soft-serve ice cream machines.
The total bacteria level was 12,000,000.
One of the reasons is they noted when giving out a sample flavor in a small paper cup, the workers used the same cup to refill with another flavor for the customer. Putting the used cup under the dispenser pulled bacteria into the machine.
