Term
contaminated
Definition
contains harmful substances not originally present in it
Term
hazard
Definition
any substance in food that can cause illness or injury. Four types: biological, chemical, physical, allergens
Term
microorganism
Definition
a tiny, usually single-celled organism that can be seen only with a microscope
Term
pathogen
Definition
microorganism that can cause disease
Term
four kinds of microorganisms that can contaminate food and cause illness
Definition
bacteria
viruses
fungi
parasites
Term
four types of bacteria
Definition
harmless, beneficial, undesirable, disease-causing
Term
intoxications
Definition
caused by poisons (toxins) the bacteria produce while they are growing in the food, before it is eaten. it is these poisons, not the bacteria themselves, that cause the diseases
Term
infections
Definition
caused by bacteria (or other organisms) that get into the intestinal system and attack the body. Disease is caused by the bacteria themselves as they multiply in the body
Term
toxin-mediated infections
Definition
caused that get into the body and grow. Disease is caused by poisons the bacteria produce as they grow and multiply in the body. Most food-borne diseases are these
Term

Term
Food Danger Zone
Definition
Temperatures between 41 degrees F and 135 degrees F promote the growth of disease-causing bacteria
Term
aerobic
Definition
bacteria that require oxygen to grow
Term
anaerobic

Term
facultative
Definition
bacteria that can grow either with oxygen or without it. This is most bacteria in food that cause disease.
Term
lag phase
Definition
time that bacteria needs to adjust to their surroundings before they start growing. May last 1 hour or somewhat longer.
Term
potentially hazardous foods
Definition
foods that provide a good environment for the growth of disease-causing organisms
Term
sanitize
Definition
to kill disease-causing bacteria
Term

smaller than bacteria; genetic material surrounded by a protein layer. Can't reproduce or multiply unless they are inside a living cell. Food-borne viral diseases are usually caused by contamination from people, food contact surfaces, or contaminated water.
Term
parasites
Definition
organisms that can survive only by living on or inside another organism
Term
host
Definition
the organism a parasite lives in and takes nourishment from
Term
fungi

Term
one-stage cooling method
Definition
cool foods to below 41 degrees F in no more than 4 hours. If the food does not reach this temperature in 4 hours, it must be reheated to 165 degrees F and held at that temperature at least 15 seconds and then cooled again. Should be used if the item was made from potentially hazardous foods that were at room temperature when preparation was begun.

microwave radiation
Definition
the radiation generated by the oven penetrates partway into the food, where it agitates the molecules of water. The friction this agitation causes creates heat, which cooks the food. (note: completely waterless food will not heat in a microwave; large pieces of food heat on the inside by conduction, not the radiation)
Term
