If perishable food has been in the danger zone for more than two hours, what should you do?

• A. Discard it.
• B. Use it if it smells okay.
• C. Reheat and eat.
• D. Freeze it.

Answer: (A)

Bacteria multiply quickly when perishable foods sit in the danger zone, which is roughly 40 to 140 degrees Fahrenheit. If food stays there for more than two hours, harmful levels can build up, making it unsafe to eat. Reheating to a hot temperature might kill some bacteria, but it won’t remove any toxins they may have produced, and some toxins survive heating. Smelling or looking at the food isn’t reliable for safety, since pathogens can be present even when there’s no noticeable off smell or texture. Freezing stops further growth but doesn’t kill existing bacteria or toxins, so it won’t make the food safe after it’s already spent too long in the danger zone. The safest action is to discard the food to prevent illness.
