Toothbrush Holders
The high bacteria levels in toothbrush holders (27 percent had coliform, 14 percent had staph) are likely because toothbrush holders tend to be so close to the toilet -one flush can unleash fecal-containing aerosols. And who ever thinks to clean the holder? No wonder 64 percent harbored mold and yeast.
Cleaning tip: Toss the toothbrush holder in the dishwasher if safe, or wash with hot soapy water twice a week.
