Bacteria grow most rapidly in the range of temperatures between 40 °F and 140 °F, doubling in number in as little as 20 minutes. This range of temperatures is often called the “Danger Zone.” Never leave food out of refrigeration over 2 hours.
What is the 40 to 140 rule?
The 40 140 rule is an easy to remember rule for food safety temperatures. 40°F is the internal meat temperature when the cooking begins. … Food needs to go from 140°F to the lower 40°F within 2 hours of refrigeration.
What is the 2 4 hour rule?
The 2-hour/4-hour rule is a good way to make sure potentially hazardous food is safe even if it’s been out of refrigeration. The rule has been scientifically checked and is based on how quickly microorganisms grow in food at temperatures between 5°C and 60°C.
What is the danger zone for food UK?
Bacteria usually grow in the ‘Danger Zone’ between 8°C and 60°C. Below 8°C, growth is stopped or significantly slowed down. Above 60°C the bacteria start to die. Time and temperature are both important because proteins need to be heated up for a long enough time for them all to be broken down.
What is the safe zone for food temperature control?
What is a safe temperature? Safe temperatures are 5 °C or colder, or 60 °C or hotter. Potentially hazardous foods need to be kept at these temperatures to prevent any food-poisoning bacteria, which may be present in the food, from multiplying to dangerous levels.
What is the 4 hour rule?
What is the 4-hour/2-hour rule? Studies show that food can be safely held out of temperature control for short periods of time without significantly increasing the risk of food poisoning. … However, the total time in the temperature danger zone must not be longer than 4 hours.

What temperature will kill bacteria?
Bacteria multiply rapidly between 40 and 140 degrees. Bacteria will not multiply but may start to die between 140 and 165 degrees. Bacteria will die at temperatures above 212 degrees. 2.3: How to Take Food Temperatures Know how to get an accurate reading with your thermometer!
What is a high risk food?
Foods that are ready to eat, foods that don’t need any further cooking, and foods that provide a place for bacteria to live, grow and thrive are described as high-risk foods. Examples of high-risk foods include: cooked meat and fish. gravy, stock, sauces and soup. shellfish.
What is the 2 hour & 4 hour rule when it comes to temperature control of food?
The 2 Hour/ 4 Hour Rule tells you how long freshly potentially hazardous foods*, foods like cooked meat and foods containing meat, dairy products, prepared fruits and vegetables, cooked rice and pasta, and cooked or processed foods containing eggs, can be safely held at temperatures in the danger zone; that is between …
What is the proper way to take food temperature?
Insert the stem of a probe thermometer into the thickest part of the food, or in the centre of the food if the food is even in thickness. If the food is liquid (e.g., stew or soup) stir it to make sure the heat has been evenly distributed before inserting the thermometer in order to get an accurate temperature reading.
Which food is at temperature that allows bacteria to grow well?
Warmth – the ‘danger zone’ temperatures at which bacteria grow best are between 5ºC and 63ºC. Food – like any other living things, germs need food to grow. High-risk foods that bacteria love best include dairy products, meat, poultry, fish and shellfish.
