And to PP questioning using soap vs just plain water on hands- washing with soap is far more effective than water alone (which is still much better than nothing). Especially if used properly, not just a cursory rub of the hands and rinse.
It wasn't really about hands, I was just comparing rinsing fruit and veg to hand washing. They say to rinse salad before eating to reduce listeria etc. But how effective is it really given it doesn't involve soap? Or is it different because the bacteria doesn't adhere to fruit and veg the same way it does to our hands?
