For how long must food maintain its internal cooking temperature to be considered safe to serve?

To ensure food safety, it is critical to maintain specific internal cooking temperatures for adequate time to effectively kill harmful microorganisms. The guideline of maintaining the internal cooking temperature for a minimum of 15 seconds is established based on food safety standards, particularly for potentially hazardous foods.

This timeframe allows sufficient heat exposure to eliminate pathogens that can cause foodborne illness. Cooking food to the recommended temperatures is essential, but the duration it holds that temperature is just as important. For example, when poultry is cooked, achieving an internal temperature of 74°C (165°F) is crucial, but ensuring it stays at that temperature for at least 15 seconds supports pathogen destruction.

Shorter timeframes may not guarantee that harmful organisms are entirely eradicated, while longer times may not be necessary if the food has already been brought to a safe temperature quickly. The 15-second mark is a practical balance derived from research and food safety protocol to balance time and temperature effectively for safe food preparation.
