What is the TDZ?
Time and Temperature Harmful microorganisms grow well in foods held between temperatures of 41 degrees Fahrenheit and 135 degrees Fahrenheit. This temperature range is also known as the Temperature Danger Zone (TDZ). The less time foods spend in the TDZ, the less time harmful microorganisms have to grow.
Why is acidity important in FATTOM?
Bacteria grow best in an environment that is slightly acidic or neutral (pH level of 4.6-7.5) and they flourish in a pH range between 6.6 and 7.5. Most bacteria will not grow at pH levels below 4.6 because the environment is too acidic.

What two FAT TOM conditions are the easiest for a operation to control? Time and temperature. To control time, limit how long TCS food spends in the temperature danger zone.
What does acidity mean in Fattom?
There are sufficient nutrients available that promote the growth of microorganisms. Protein-rich foods, such as meat, milk, eggs and fish are most susceptible. A. Acidity. Foodborne pathogens require a slightly acidic pH level of 4.6–7.5, while they thrive in conditions with a pH of 6.6–7.5.
What does YOPI stand for?
YOPI (young, old, pregnant, immunosuppressed) stands for especially vulnerable sections of the population who are prone to getting food-borne infections because their immune system is either impaired or not fully developed yet.
Can bacteria grow on fat?
Most materials in laboratories and health-care centers have small amounts of lipids on their surface, and thus may support the proliferation of lipophilic bacteria. … Lipophilic bacteria may also proliferate in diet fat.
What is Fattom in food safety?
FATTOM is an acronym used to describe the conditions necessary for bacterial growth: Food, acidity, time, temperature, oxygen, and moisture.
What are the 5 best cooling procedures?

Is baked Potato A TCS food?
Many potatoes were baked or boiled and then served in restaurants, catering, healthcare and other foodservice operations. And surprisingly, cooked potatoes pose a food safety risk, because they are considered a Time/Temperature Control for Safety (TCS) food.
Why is Fattom important?
FAT TOM is a mnemonic device used in the food service industry to describe the six favorable conditions required for the growth of foodborne pathogens. … Understanding the optimal conditions for bacterial growth can potentially help you reduce your risk for bacterial infections and food poisoning.
What determines the survivability of pathogens?
Moisture content appears to be one of the most influential factors in determining the survival time of pathogens. In general the survival time will increase as the moisture content increases. In general, survival time increases as temperature decreases.
Do pathogens need oxygen to grow?
1 All pathogens need oxygen to grow. 2 The most important way to prevent foodborne illnesses caused by viruses is to control time and temperature. 3 Salmonella Typhi is commonly linked with ground beef.
Why does beef turn green?
Some meat may also show an iridescent sheen. This is because meat contains iron, fat, and other compounds. When light shines on a slice of meat, it splits into colors like a rainbow.

Why does my ice cream melt in the freezer?
Ice cream stored in the freezer door is exposed to warm air more often, and that can cause the ice cream to soften or melt. When ice cream thaws and refreezes, the tiny pockets of air created during processing escape, resulting in large ice crystals and a hard and grainy texture.
