Question:
I have been researching Germs and Bacteria on Shopping Cart Handles. (They are actually fomites).

Has anyone else researched or had thoughts about these disease carrying fomites.

Answer:

"Fomites" is a term for any inanimate object that can carry disease-causing organisms. Your cutting board, kitchen sink, the change in your pocket and even that pen you keep putting in your mouth are all fomites. Very few things we encounter in our everyday activities are sterile, or microbe-free, including us. At birth, microbes immediately begin colonizing our bodies like they do with most every object in the world. They float around until they come in contact with a surface that offers food and shelter. You are most likely to find microbes in and on dark, moist objects that frequently come into contact with food, dirt or vegetation. Bathroom surfaces, hairbrushes, refrigerators, kitchen sinks and cutting boards often have lots of microbes on them... and shopping cart handles. However, shopping cart handles, doorknobs, and walls have fewer because they are nutrient-poor and dry.
Most of the microbes on our bodies and other surfaces are harmless, but some are pathogenic or disease-causing. For this reason, the answer is a simple one - we wash our hands with soap and water. This is not a subject to become paranoid over (I'm not saying you are - just a loose term I'm using) unless your immune system is zero.
