I don't want to spend a lot of time on this since I assume everyone already knows this but it doesn't hurt repeating. Raw chicken can be a carrier for salmonella which is why it is important to always cook chicken thoroughly before eating. Dry, chewy overcooked chicken is preferable to getting food poisoning. When working with raw chicken always be sure to thoroughly clean everything that has been in contact with the chicken. Don't just limit yourself surfaces that were in direct contact with the chicken but get the surrounding area as well. Be sure to wash your hands as well.
