i watch people wipe down the handles and they think they are protecting themselves. but they never wipe down the seat where the babies sit with their diapers.
But people don’t often put their hands in the basket, and that’s where you get a lot of contamination.
A huge amount of e coli is found on basket handles, because people don’t wash their hands after leaving the toilet, and then push the carts through the market. They are quite filthy, like money - but who washes their money?
Little ones sit in the cart and put their hands on the handle. My son at 6 mos, got his very first really vicious infection many years ago when I took him through the market and he held onto the handle of the cart while seated. Ended up in the ER. I would wipe down those handles if you have a little one.
