Oh yeah we always wash produce. I don't think this washes off though once it's contaminated.
I have lupus so this would certainly do a doozy on me. DH is a produce manager and this apparantly happened a couple of weeks or so ago too. He said they had to throw out all of the tomatoes and the only one's they have been getting in are the cherry. No larger tomatoes at all.
Thank goodness I have not been on a tomato binge lately! It will probably be some time before I will want to eat any now.
