How to Handle Fresh Chicken Safely:
Fresh Chicken: Chicken is kept cold during distribution to retail stores to prevent the growth of bacteria and to increase its shelf life. Chicken should feel cold to the touch when purchased. Select fresh chicken just before checking out at the register. Put packages of chicken in disposable plastic bags (if available) to contain any leakage which could cross-contaminate cooked foods or produce. Make the grocery your last stop before going home.
At home, immediately place chicken in a refrigerator that maintains 40°F. Use it within 1 or 2 days, or freeze it at 0°F. If kept frozen continuously, it will be safe indefinitely.
