  • Marinate meats in the refrigerator, not on the counter. Bacteria spreads rapidly at room temp.

  • Defrost frozen beef in the refrigerator, never at room temperature.

  • Cook beef thoroughly to the proper internal temperature to kill bacteria.

  • Cool and refrigerate cooked beef promptly. Don’t let it sit out more than 2 hours.
