[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.

Food should be removed from "the danger zone" (see below) within two-four hours, either by cooling or heating. While most guidelines state two hours, a few indicate four hours is still safe. T: 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).
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 ...
The temperature range of 40-140°F is widely known as the temperature danger zone—a.k.a. the climate where bacteria can thrive. The USDA reports that bacteria can start taking over your ...
The temperature must be checked every 4 hours or else labeled with a discard time. Although monitored hot food can be held indefinitely in this way without a food safety concern, the nutritional value, flavor, and quality can suffer over long periods.
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
This range is called the temperature danger zone. The longer that food is in the danger zone, the more bacterial will grow. Hot food needs to stay hot and cold food needs to stay cold.
The biochemical process of fermentation itself creates a lot of residual heat which can take the must out of the ideal temperature range for the wine. Typically, white wine is fermented between 18–20 °C (64–68 °F) though a wine maker may choose to use a higher temperature to bring out some of the complexity of the wine.
