The required minimum cooking temperature for ground beef is 155°f (68°c). why must ground beef be cooked to this temperature?

To kill the bacteria present in the meat, is the correct answer.

Explanation:

According to USDA recommendations, the ground beef should be properly cooked before eating. USDA recommends it because E. Coli and Salmonella bacteria can get into the beef and contaminate it during the meat's production and supply chain. The meat is easily susceptible to contamination. Although the bacteria is harmless it can multiply rapidly at temperatures above 40 degrees Fahrenheit. Cooking the meat at high temperatures can kill the bacteria.
