[11] [12] To prevent time-temperature abuse, the amount of time food spends in the danger zone must be minimized. [13] A logarithmic relationship exists between microbial cell death and temperature, that is, a small decrease of cooking temperature can result in considerable numbers of cells surviving the process.

Temperature Foodborne pathogens grow best in temperatures between 41 and 135 °F (5 and 57 °C), a range referred to as the temperature danger zone (TDZ). They thrive in temperatures that are between 70 and 104 °F (21 and 40 °C). [3] O: Oxygen Almost all foodborne pathogens are aerobic, that is requiring oxygen to grow.
Potentially Hazardous Food is a term used by food safety organizations to classify foods that require time-temperature control to keep them safe for human consumption. A PHF is a food that: Contains moisture – usually regarded as a water activity greater than 0.85; Contains protein
Stay out of the temperature danger zone Many people are rightly cautious about leaving raw meat out. The USDA describes 40 to 140°F as the temperature “danger zone,” where bacteria growth is ...
That lets the raw meat reach the temperature danger zone (40 to 140 degrees Fahrenheit) for a long period of time, giving bacteria time to multiply quickly, which increases the chances of getting ...
According to the USDA, the food danger zone is between 40 degrees F and 140 degrees F. The temperature danger zone refers to a temperature range in which bacteria grow and thrive.
[25] [26] The length of time before a food becomes unsafe to eat depends on the type of food it is, the surrounding environment, and the method with which it is kept out of the danger zone. Always refrigerate perishable food within 2 hours—1 hour when the temperature is above 90°F (32.2°C).
With cold food, it should be discarded after sitting at room temperature for over two hours, and one hour if it’s been sitting at a temperature above 90F. Show comments Advertisement
