The Cleaniness of Eating Mushrooms

Most chefs stress the fact that white button mushrooms, and others, should not be washed to be cleaned. They say to either lightly brush them or just pat them with a cloth or paper towel to get the "dirt" off to clean them, and then cook or eat them raw. Do not "wash" them, to clean them, because the chefs says the mushrooms get waterlogged, and I believe something happens to the taste. Well, as a little girl my Dad took me to a mushroom farm. It was disgusting because of the smell of manure. The mushrooms were in trays, enveloped totally in the manure in trays, that were stacked high according to the sizes and I don't remember what else. We were in darkness, and my Dad would go from one area to the next buying trays from all over. Years later, I became the buyer and I don't remember much other than the awful smell, the sizes, the darkness and how much I still loved to eat mushrooms. To prepare I washed them with water, got off all the excess manure, and depending on how the mushroom was to be prepared, stuffed, quick boiled in lots of salt then kept in that same salted water to be eaten with sour cream, fried with butter,
