How can we prevent bacteria within food from multiplying?

• A. Keeping food at room temperature for long periods
• B. Cooking food quickly to reduce time at room temperature
• C. Storing below 5°C or above 63°C
• D. Reheating leftovers multiple times

Answer: (C)

Bacteria multiply best within a specific temperature range, roughly between 5°C and 63°C. Keeping food out of this “danger zone” prevents their growth: small, cold environments slow or stop reproduction, while hot environments above 63°C keep bacteria from multiplying. Storing food below 5°C or hot above 63°C directly applies this idea, making it the most reliable way to prevent growth. Leaving food at room temperature for long periods keeps it in the danger zone, allowing rapid bacterial growth. Reheating leftovers multiple times can kill some bacteria but doesn’t guarantee all are eliminated or kept out of the danger zone, and cooking quickly to reduce time at room temperature doesn’t ensure safe temperatures are maintained throughout serving.
