1) Ask your butcher or store clerk if your steak or beef roast has been mechanically tenderized.
2) If they say yes or are uncertain, cook your steak or roast thoroughly - like you would cook ground beef.
3) Use a digital thermometer to ensure safe internal temperature of 71°C.
4) Keep raw meats separate from other foods when you store them.
5) Keep knives, cutting boards and counters clean.
