It was the bottom of the purses that contained the majority of the germs.
And the reason is simple.
We ladies set down our bags on the floor in public restrooms. We then put them on the microbe-laden sink to wash our hands.
Many women also place their purse in the toddler seat of the shopping cart at the grocery store. (Those seats typically cradle the bums of children wearing leaky diapers.) They toss them under their chair in a restaurant where the last customer just dropped a shrimp. And who doesn’t plop their bag on the ground from time to time, possibly in the same spot where the neighbor just walked his dog.
“Purses are becoming subways for micro organisms,” said microbiologist Chuck Gerba. “They’re being transferred from one location to another. So it’s like germ ‘public transportation’.”
