No, You should not wash packaged chicken. In fact, a recent USDA study confirms that you put yourself and those around you at risk of illness when you wash or rinse raw poultry before cooking it. In an article, the Centers for Disease Control and Prevention (CDC) explained that “During washing, chicken juices can spread in the kitchen and contaminate other foods, utensils, and countertops.” The article also added that it’s important to thoroughly wash your hands after handling raw poultry and never use the same cutting board to prep other ingredients if raw chicken has touched it.
Always cook chicken thoroughly. Chicken should always be cooked to at least 72 °C internal temperature as measured with a food thermometer; leftovers should be refrigerated no more than two hours after cooking.
