Nonsense. Do you have kids? Kids have "blow-outs" all the time that send poop exploding out of the diaper and onto their pants and shirts (and socks...and shoes...). These clothes, they don't get boiled. We soak them in water and detergent for a few hours and then throw them in the washer with the rest of our laundry. I have two kids, including one in diapers, and I've never once had any hygiene issues and you better believe that my washer has seen some poop.
