Final answer:
Chicken must be cooked to a temperature of 165°F (74°C) for at least 15 seconds to ensure bacteria are killed.
Step-by-step explanation:
To kill bacteria in chicken, it should be cooked to an internal product temperature of 165°F (74°C) or higher for at least 15 seconds. This temperature and time combination is sufficient to ensure that foodborne bacteria are destroyed, making the chicken safe to eat. It's important to use a meat thermometer to accurately measure the internal temperature of the chicken to prevent foodborne illness.
