The market here which has markets on different days, in different places
have cleaned up produce. Not scrubbed, but nothing has dirt clinging to it so that it falls off into ones basket. Most of the field greens have been swished in a tub of water, shaken then put into open plastic bags/ The fruits such as berries, peaches, apples, pears, kiwi, etc, are not washed. I have often commented on how clean every thing looks and they will tell you to wash before eating or storing. Since it is organic, when I do wash the greens or other produce, I always find a lady bug, praying mantis, or little critters, especially in the broccoli, and I don't want those things in my fridge. The tomatoes are not washed either.
I learned from a friend long ago, to wash all my lettuces, kales, chard when I get home and put into a spinner. It used to be a pain, but now I am used to it and love that I can have a salad ready in no time. Plus I find that my husband eats more greens with his sandwiches.
