NO! Never, ever rinse or wash a raw piece of meat. This adds moisture to the skin or outside of the cut and will prevent browning during cooking. Rinse, and you're creating one more hurdle to crispy chicken skin or wonderfully cooked steak with a nice crust. More importantly, rinsing chicken or any of its animal protein friends could potentially splash foodborne germs like salmonella, campylobacter, or e. coli all over your sink and kitchen. Just. Don't. Do it.
