Which of the following food products has been properly cooked?

The choice that indicates a properly cooked food product is the pork chop cooked to an internal temperature of 145° F for 15 seconds. This is considered safe because the recommended minimum internal temperature for cooking pork is 145° F, and maintaining this temperature for at least 15 seconds ensures that any harmful bacteria present in the meat are effectively killed, making it safe to consume.

Cooking to the correct temperature is crucial in preventing foodborne illness, and the specified time at that temperature further guarantees that the heat has penetrated the food adequately.

In contrast, the other choices do not meet the proper guidelines for safe cooking temperatures. For instance, a whole roasted chicken needs to reach a higher internal temperature of at least 165° F to be considered properly cooked. Similarly, ground beef should also reach a minimum internal temperature of 160° F to ensure safety, while a whole turkey requires a cooking temperature of 165° F to be safe for consumption. Thus, the choice about the pork chop aligns perfectly with the food safety standards for proper cooking.
