Overview

• Researchers sampled bacteria from 30 microwaves in homes, shared spaces, and laboratories.
• Microwaves contain 747 different bacterial genera, with the highest diversity in laboratory microwaves.
• Domestic microwaves have bacteria similar to those on kitchen surfaces, while lab microwaves host radiation-resistant microbes.
• Some bacteria found may pose health risks, but not more than other kitchen surfaces.
• Regular cleaning with diluted bleach or disinfectant spray is recommended to maintain hygiene.
