Foodborne Illness

Here are lists of foodborne illnesses, and other important information regarding foodborne illnesses: List You should know that this year, specific diseases are not included in tests and competitions!

FAT TOM

Is a device to describe the six favorable conditions required for the growth of foodborne pathogens. It is an acronym for food, acidity, time, temperature, oxygen, and moisture.

FATTOM

F

Food

There are sufficient nutrients available that promote the growth of microorganisms. Protein-rich foods, such as meat, milk, eggs, and fish are the 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. The United States Food and Drug Administration's (FDA) regulations for acid/acidified foods require that the food is to be brought to pH 4.5 or below.

T

Time

Food should be removed from "the danger zone" (see below) within two-four hours, either by cooling or heating. While most guidelines state two hours, a few indicate four hours is still safe.

T

Temperature

Food-borne pathogens grow best in temperatures between 41 to 135 °F (5 to 57 °C), a range referred to as the temperature danger zone (TDZ). They thrive in temperatures that are between 70 to 104 °F (21 to 40 °C).

O

Oxygen

Almost all foodborne pathogens are aerobic, that is requiring oxygen to grow. Some pathogens, such as Clostridium botulinum, the source of botulism, are anaerobic.

M

Moisture

Water is essential for the growth of foodborne pathogens, water activity (aw) is a measure of the water available for use and is measured on a scale of 0 to 1.0. Foodborne pathogens grow best in foods that have aw between 0.95 and 1.0. FDA regulations for canned foods require aw of 0.85 or below.

Prevention

For Food Borne Illnesses, prevention tactics include:

  • Cook meat, poultry, and eggs thoroughly.

  • Don't cross-contaminate one food with another.

  • Chill and refrigerate leftovers promptly.

  • Clean and wash all produce.

  • Report suspected foodborne illnesses to the local health department.
