Monica was surprised to learn that sterilizers, disinfectants and sanitizers are regulated by the
U.S. EPA as pesticides. Just as herbicides control weeds, and insecticides control insects,
antimicrobials control germs including bacteria, viruses and fungi.
Monica also learned what makes sterilizers, disinfectants and sanitizers different. Sterilizers are
most commonly used on medical or laboratory equipment to destroy bacteria, viruses, fungi and
the spores they produce. While disinfectants do not destroy spores, they do destroy infectious
bacteria and fungi. Sanitizers reduce the number of germs on an object to a level that meets
public health standards.
The specialist said that hand gels are meant to be used on people and are not appropriate for
use on toys. Monica then asked if soap and water or household bleach would do the trick. The
specialist explained that products claiming to clean only lack pesticidal claims, and are not
registered by the EPA. Because they are not registered, it's not known whether or not they kill
or remove germs. Monica learned that the EPA registration number, found on the label, lets
people know that the product was evaluated for potential health risks and effectiveness. Monica
found an EPA registration number on the label of her bleach container and shared it with the
specialist.
While reviewing information on the bleach label, Monica asked the specialist what, "for use on
hard non-porous surfaces," means. The specialist explained that this term is often used to describe
solid materials that do not absorb light or liquids. Monica noted that T-Rexie was definitely
absorbent and decided the washing machine was most appropriate for him. However, the toy
car was a hard non-porous surface. Since Kevin had played with it while he was sick, Monica
decided to use a solution of bleach to disinfectant it. Monica determined the dilution rate by reading
the application and mixing instructions section of the label. The specialist pointed out that the
toy must remain in the solution for at least 2 minutes to be disinfected.
In the end, Monica learned some new things and made an informed decision. She also understood
the importance of reading the product label before using any pesticide.
The U.S. Department of Health and Human Services has a great resource for selecting and using an appropriate sanitizer.
