New Study Confirms Just How Dirty Microwaves Are

How often do you clean out your microwave? According to a “swab study” conducted by Kimberly Clark, it should be cleaned after every use. Here’s why: In their exams of almost 5,000 locations in a variety of settings, 48 percent of microwave door handles tested had adenosine triphosphate (ATP) counts of 300 or higher.  (ATP is a molecule that provides the energy needed for living things).  An ATP count of 300 or higher represents a surface that’s at high risk of transmitting illness.  Further research found the presence of E. coli inside a swabbed microwave.  Of the study, Julie Torruellas-Garcia, PhD, who analyzed the samples, said: “We use it [the microwave] to cook our food, but also to defrost meat.  Raw meats carry bacteria like E. coli and Salmonella. Sometimes, the food splatters around the microwave and we don’t always clean it.”
