The danger zone is the temperature range in which food-borne
Food-borne bacteria, in large enough numbers, may cause
Time and temperature control safety (TCS) plays a critical role in food handling.[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] In addition to reducing the time spent in the danger zone, foods should be moved through the danger zone as few times as possible when reheating or cooling.[15]
Foods that are potentially hazardous inside the danger zone:[16]
- Meat: beef, poultry, pork, seafood
- Eggs and other protein-rich foods
- Dairy products
- Cut or peeled fresh produce
- Cooked vegetables, beans, rice, pasta
- Sauces, such as gravy
- Sprouts
- Any foods containing the above, e.g. casseroles, salads, quiches
According to Bryan (2004), a more complex, but more comprehensive picture of food safety hazards can be given by full consideration of the many factors involved. He advocates seeing the danger zone as "a series of ranges that represent different degrees of hazards and risks." He presents the danger zone in a chart of time versus temperature as having a zone of high danger in which foods are at temperatures between 30C and 45C for several hours, surrounded by two zones of lesser danger involving exposure at lower temperatures for longer periods of time.[17]
