Roasts of pork, beef, veal, and lamb should be cooked to what MINIMUM internal temperature?

A roast is a large and thick cut of meat and requires the longest cooking time to ensure that it is cooked thoroughly. Roasts of pork, beef, veal, and lamb should be cooked to 145°F for 4 minutes. Roasts may also be cooked at lower temperatures if the time is increased accordingly. If the roast is injected with flavoring, it falls into a different category and should be cooked to an internal temperature of 155°F for 17 seconds.
