Final answer:
After TCS food has reached 165 Fahrenheit in a microwave oven, it can be considered safe to eat, as most harmful bacteria and pathogens are killed at this temperature.
Step-by-step explanation:
After TCS food has reached 165 Fahrenheit in a microwave oven, the food should be considered safe to eat. This is because at 165 Fahrenheit, most harmful bacteria and pathogens are killed, reducing the risk of foodborne illness.
It is important to use a food thermometer to verify the temperature of the food. Simply gauging the food's temperature based on visual cues or touch is not sufficient and may lead to undercooking, leaving some bacteria alive.
Therefore, always ensure that TCS (Time/Temperature Control for Safety) foods such as meat, poultry, fish, eggs, and leftovers reach an internal temperature of 165 Fahrenheit to ensure food safety.
