CP-FS Study Guide Exam Questions
and Answers 100% Pass
What is the primary goal of any food safety program? - ✔✔To prevent
foodborne illnesses and foodborne disease outbreaks.
Foodborne illness - ✔✔An acute illness resulting from eating contaminated
food.
Foodborne disease outbreaks - ✔✔the occurrence of two or more cases of
the same illness resulting from the consumption of the same food.
confirmed disease outbreak - ✔✔a foodborne disease outbreak in which
laboratory analysis of appropriate specimens identifies a causative agent
and epidemiological analysis implicates the food as the source of the
illness.
pathogen - ✔✔a disease producing organism

,aerobic organism - ✔✔an organism that requires oxygen to live
anaerobic organism - ✔✔an organism that requires the absence of oxygen
to live.
facultative anaerobe - ✔✔an organism that can multiply with or without
the presence of oxygen.
Bacterial toxins
Exotoxins - ✔✔Exotoxins- Are produced during the growth phase of
certain kinds of bacteria and are liberated into the medium or tissue.
Exotoxins are protein in nature and their reactions are specific.
Examples-Clostridium botulinum produces an exotoxin (neurotoxin) of
unusual potency which affects only neurological tissue. Other examples of
exotoxins are tetanus toxin, shiga toxin, and diphtheria toxin.
Neurotoxins- chemicals which produce their primary toxic effects on the
nervous system.

,neurotoxins - ✔✔chemicals which produce their primary toxic effects on
the nervous system. Toxins can damage cells of the central nervous system
(brain and spinal cord) or the peripheral nervous system (nerves outside
the central nervous system)
Bacterial toxins
Endotoxins - ✔✔Can be extracted from a wide variety of gram-negative
bacteria. Higher doses of endotoxins are required to produce a lethal effect
in the experimental aninmal than are requied for exotoxins. The effects
produced by endotoxins on the host are systemic such as fever and general
body reactions, rather than strictly neurological effects, as is the case with
most exotoxins. Endotoxins are found mostly in gram-negative bacteria,
and are obtained subsequent to the death and autolysis of the cells. The
endotoxins are extracted from and associated with the cell structure.
Examples- S. typhosa, E. coli, and aeruginosa.

, Enterotoxin - ✔✔is a harmful substance produced by certain bacteria,
which is specifically dangerous to parts of your gastrointestinal tact. The
substance enters your stomach and intestines when you eat tainted food or
water, causing symptoms such as cramps, nausea, vomiting, or diarrhea.
Viruses - ✔✔Are submicroscopic parasites that are smaller than bacteria.
Some viruses cause foodbores illnesses. Viruses cannot multiply outside of
a living cell. Viruses are classified an infections. Viruses such as norovirus,
hepatitis A, and rotavirus are directly related to contamination from
human feces. Ibn most cases, contaminaination of food by viruses is the
result of cross contamination by ill food employees or unclean equipment
and utensils.
Parasites - ✔✔Are plants or animals that live on or in another plant or
animal-the host to survive. Parasites live and reproduce within the tissues
and organs of infected human and animal hosts and are often excreted in
feces. They range in size from single-celled organisms to worms visible
with the naked eye. Parasites are of most concern in seafood.
