[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. [14]
Potentially Hazardous Food has been redefined by the US Food and Drug Administration in the 2013 FDA Food Code to Time/Temperature Control for Safety Food. [1] Pages 22 and 23 (pdf pages 54 and 55), state the following:
A time temperature indicator (TTI) is a device or smart label that shows the accumulated time-temperature history of a product. Time temperature indicators are commonly used on food, pharmaceutical, and medical products to indicate exposure to excessive temperature (and time at temperature). [1] In contrast, a temperature data logger measures ...
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.
If an environment is high in starch or protein, water, oxygen, has a neutral pH level, and maintains a temperature between 5°C and 60°C (danger zone) for even a brief period of time (~0–20 minutes), [19] bacteria are likely to survive. [20] Example of biological contamination: Tainted Romaine Lettuce

A boy who said he was forced to give oral sex to a male guard on three different occasions first reported the abuse in March 2010. In a police report from October of that year, a Pembroke Pines officer noted: “This is the third time this victim has alleged sexual abuse.”
The D-value at an unknown temperature can be calculated knowing the D-value at a given temperature provided the Z-value is known. The target of reduction in canning is the 12- D reduction of C. botulinum, which means that processing time will reduce the amount of this bacteria by a factor of 10 12 .
