Cards

Term
Spoilage
Definition
Denotes unfitness for human consumption due to chemical or biological causes
Term
Criteria for assuring foods are fit:
Definition
The desired stage of development or maturity of the food.
Freedom from pollution at any stage in production and subsequent handling.
Freedom from objectionable chemical or physical changes resulting from action of food enzymes; activity of microbes, insects and rodents, invasion of parasites, and damage from pressure, freezing, heating or drying.
Term
Contamination
Definition
The presence of harmful substances in -food.
Term
CDC recommends which activities to improve food safety
Definition
More training for food handlers.
Better protocols for investigating foodborne outbreaks.
Hazard analysis in food operations.
Improved data on how pathogenic organisms are carried and spread, how food preparation contributes to proliferatio, and how food handling contribute to an outbreak.
Term
Types of Microorganisms
Definition
Bacteria, Viruses, Parasites and Fungi
Term
Microbiological Spoilage
Definition
Food spoilage caused by microorganisms.
Term
FAT TOM
Definition
F is for Food; specifically carbs and proteins
A is for Acidity: pH of 4.6 to 7.5
T is for Temperature: 41 deg to 135 deg
T is for Time: amount of time in danger zone
O is for Oxygen: some need oxygen
M is for Moisture: water activity of .85 or higher is ideal for growth.
Term
Bacteria
Definition
microscopic, unicellular organisms of varying size and shape, including sperical, rod and spiral.
Term
Phases of the Bacterial Growth Curve
Definition
Lag Phase-initial stage where, although bacteria cells exist, little to no growth occurs.
Log Phase-a period of rapid growth in a relatively short period of time.
Stationary Phase- the rate of growth is slowed and eventually stops as bacterial cells begin to die.
Death Phase-bacterial cells die more rapidly than new cells are created due to lack of nutrients and the excess waste the cells create.
Term
pH value
Definition
Degree of a food's acidity or alkalinity.
Term
Potentially Hazardous Food
Definition
Food items that require temperature control because they are capable of supporting growth of pathogenic microorganisms or toxin formation.
Term
Thermal Death time
Definition
Time required at a specific temperature to kill a specified number of vegetative cells or spores.
Term
Aerobic Bacteria
Definition
Bacteria that need oxygen to grow
Term
Anaerobic Bacteria
Definition
Bacteria that reproduce without oxygen.
Term
Fungi
Definition
includes single and multicellular organisms such as molds, yeasts, and mushrooms. Molds are larger than bacteria and more complex in structure. They grow on a wide range of substrates-moist or dry acid or nonacid, high or low in salt or sugar. 77 degrees to 86 degrees
Term
Biochemical Spoilage
Definition
Caused by natural food enzymes, which are complex catalysts that initiate reactions in foods. Off-flavors, odors, or colors may develop in foods if enzymatic reactions are controllable.
Term
Physical Spoilage
Definition
Temperature changes, moisture, and dryness can cause physical spoilage of food. For example, excessive heat, for example, breaks down emulsions, dehydrates food, and destroys certain nutrients.
Term
Physical Contamination
Definition
Occurs when particles that are not supposed to be in a food product are accidentally introduced into that product.
Term
Chemical Spoilage
Definition
result from interaction of certain ingredients in a food or beverage with oxygen or light.
Term
Chemical Contamination
Definition
Occurs when substances such as chemicals, toxic metals, sanitizers and so on are introduced into a food product. example: Contamination of food with food service chemicals, such as pesticides, detergents, and sanitizers.
Term
Integrated Pest Mgmt
Definition
an alternative approach being used in agriculture to control pests; it is also a program in foodservice operations to prevent pest from entering an operation or to eliminate them if they do enter.
Term
Foodborne Pathogen
Definition
An infecting agent, any virus, microorganism, or other substance that causes disease.
Term
Foodborne Intoxications
Definition
Caused by toxins formed in food prior to consumption.
Term
Foodborne Infection
Definition
Caused by activity of large numbers of bacterial cells carried by the food into the gastrointestinal tract.
