What temperature does food need to be cooked to kill bacteria?
Pathogenic bacteria grow quickly in food at temperatures between 40 to 140°F (5 to 60°C). In order to kill these bacteria, it’s important to cook all foods to a safe internal temperature. The CDC lists the following temperature guidelines for several common types of food: poultry, whole or ground: 165°F (74°C)
How to kill the bacteria in your food?
To kill the bacteria in your food, you must heat the food to a high temperature, for a certain period of time. When using a probe to check the temperature of your food items, it must display the temperature for a certain length of time – such as 80 °C for 6 seconds.
What is the temperature danger zone for food?
The temperature danger zone is between 8 °C and 63 °C. Temperatures below 8 °C make it significantly more difficult for bacteria to grow; however, as best practice, we recommend chilled food is kept below 5 °C. Remember also that freezing food doesn’t eliminate bacteria, it just prevents them from growing.
What is the highest temperature that bacteria can survive?
Some bacteria can survive at very high temperatures. These types of bacteria are called thermopiles, which means “heat loving.” Thermophiles are harmless to humans and grow best at temperatures between 113 to 176°F (45 to 80°C). They’re often found in hot springs and in hydrothermal vents deep in the ocean.

Below 8°C, growth is stopped or significantly slowed down. Above 60°C the bacteria start to die.
What temperature range will destroy most bacteria?
Above 74°C (or 165°F), bacteria die, although spores and toxins may survive. Food that is being cooked or reheated should hit 74°C (or 165°F). You can hold hot food for service at 60°C (or 140°F).
Does heat destroy all bacteria?
Myth: If you let food sit out more than 2 hours, you can make it safe by reheating it really hot. Fact: Some bacteria, such as staphylococcus (staph) and Bacillus cereus, produce toxins not destroyed by high cooking temperatures.
What temperature is effective in destroying bacteria?
Specific temperatures must be obtained to ensure the microbicidal activity. The two common steam-sterilizing temperatures are 121°C (250°F) and 132°C (270°F). These temperatures (and other high temperatures)830 must be maintained for a minimal time to kill microorganisms.
Can bacteria survive 700 degrees?
In a different but equally harsh setting, bacteria and archaea grow at the bottom of the ocean around deep sea vents (Figure 9.38), where temperatures can reach 340 °C (700 °F). In fact, some of those bacteria and archaea are the primary producers of the vent ecosystem, providing fixed carbon for the other organisms.
What is the temperature range of the temperature danger zone?
The temperature range in which disease causing bacteria grow best in TCS food is called the temperature danger zone. The temperature danger zone is between 41°F and 135°F. TCS food must pass through the temperature danger zone as quickly as possible. Keep hot food hot and cold food cold.
What kills bacteria cold or hot?
Air temperature is key for bacteria. In general, cold air kills germs while warm air incubates them.
Can bacteria survive in extreme heat?
Bacteria can live in hotter and colder temperatures than humans, but they do best in a warm, moist, protein-rich environment that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria thrive in extreme heat or cold, while others can survive under highly acidic or extremely salty conditions.
Why are bacteria killed by heat?
Heat kills bacteria by denaturing these essential proteins. As the temperature rises, the weakest bonds that keep protein structures together start to break, followed by the stronger bonds with rising temperatures. What happens to protein structures during denaturation?
What happens to bacteria at 63 degrees?

What happens to bacteria at 63 degrees?
Bacteria stops growing at 8°c and below, and at 63°C or above. You should store food at these temperatures. Bacteria is killed at 100°C and above (boiling point).
Which bacteria can survive above 100 degrees?
Abstract. Microorganisms that can grow at and above 100 degrees C were discovered a decade ago, and about 20 different genera are now known. These so-called hyperthermophiles are the most ancient of all extant life; all but two genera are classified as Archaea.

Why is it Important to Record Core Temperatures?
Keeping a record of core temperatures is a crucial part of your food management system, which is known as HACCP (Hazard Analysis and Critical Control Points). Making sure that your food is cooked to the proper temperature ensures that you are showing due diligence to your local authority and protecting your customers from harm.
How Do I Record Core Temperatures of Food?
Before you begin your temperature checks, you should always make sure to clean and disinfect your probe. This should also be done after each check. To do this, you can either use a disinfectant wipe for a contact time of 30 seconds, or wash your probe in hot water that exceeds 82 °C.
Why is it important to include the date on your EHO check?

The temperature danger zone is the term used for the temperature range where food is at the most risk of developing harmful bacteria.
How to check if a probe is accurate?
You can do this by using melting ice to check that the probe registers 0°C and boiling water to check that it registers 100°C.
What is a single-celled organism?
Bacteria (singular: bacterium) are single-celled organisms which can only be seen through a microscope. They come in different shapes and sizes, and their size is measured in micrometer - which is a millionth part of a meter. There are several different types of bacteria , and they are found everywhere and in all types of environment. There are various groups of bacteria , which belong to the same family and have evolved from the same bacteria (ancestor). However, each of these types possess their own peculiar characteristics - which have evolved after separation from the original species. The classification of bacteria is based on many factors like morphology, DNA sequencing, requirement of oxygen and carbon-dioxide, staining methods, presence of flagellae, cell structure, etc. This article will give you the classification of these micro-organisms based on all these factors, as well as a few other factors.

How are bacteria classified?
Before the invention of DNA sequencing technique, bacteria were mainly classified based on their shapes - also known as morphology, biochemistry, and staining - i.e. either Gram positive or Gram negative staining. Nowadays, along with the morphology, DNA sequencing is also used in order to classify bacteria. DNA sequencing helps in understanding the relationship between two types of bacteria i.e. if they are related to each other despite their different shapes. Along with the shape and DNA sequence, other things such as their metabolic activities, conditions required for their growth, biochemical reactions (i.e., biochemistry as mentioned above), antigenic properties, and other characteristics are also helpful in classifying the bacteria.

Those infecting humans ~37C. Those helping humans by taking case of the gut, ~37C. Those that you find in melting snow ~0C. Those found in hot springs ~60C (if the spring is 60C).
What temperature should a refrigerator be?
The exact temperature threshold will depend on how the medium, and the bacterium’s internal envirunment, affects the freezing point, although even if not frozen solid, bacterial growth generally becomes very slow near 0°C, which is why refrigerators operating at 3°C - 4°C keep food from spoiling for much longer than at room temperature.

What is the classification of animals and plants?
Animals and plants are classified largely according to visible characteristics, not least, the characteristics of their reproductive organs. The binomial (genus, species) system of classification introduced by Carl Linnaeus in the 18th century has held up remarkably well on this basis, as the binomial system lends itself well to a tree-like phylogeny that links together related species.
