Will a chicken be safe to eat if cooked for 2 hours at 100 degrees celsius?

No, a chicken will not be safe to eat if cooked for 2 hours at 100 degrees celsius. The recommended internal temperature for cooked chicken is 165 degrees Fahrenheit (74 degrees celsius) to ensure the destruction of harmful bacteria, such as Salmonella and Campylobacter. Cooking chicken at 100 degrees celsius for 2 hours may not be sufficient to reach this safe internal temperature and could result in foodborne illness.
