Risk Management (Chapter 2) Flashcards
Small, living organism that can be seen only with a microscope
Microorganism
Harmful microorganism
Makes people sick when eaten or produces toxins that cause illness
Pathogens
Poison
Toxin
Four types of pathogens can contaminate food and cause
foodborne illness:
Bacteria
Virus
Parasite
Fungi
People can contaminate food when:
They don’t wash their hands after using
the restroom
They are in contact with a person who is
sick
They allow ready-to-eat food to touch
surfaces that have come in contact with raw
meat, seafood, and poultry
They sneeze or vomit onto food or food-
contact surfaces
They touch dirty food-contact surfaces and
equipment and then touch food
They store food incorrectly
Common symptoms of foodborne illness:
Diarrhea
Vomiting
Fever
Nausea
Abdominal cramps
Jaundice (yellowing of skin and eyes)
Onset times:
Depend on the type of foodborne illness
Can range from 30 minutes to six weeks
The Big Six
:
Are often found in very high numbers in an infected person’s feces
Can be transferred to food easily
Can make a person sick in small doses
Salmonella Typhi
Shigella spp.
Nontyphoidal Salmonella (NTS)
Shiga toxin-producing Escherichia coli (STEC), also knows as E.coli
Hepatitis A
Norovirus
Cannot be seen, smelled, or tasted
Will grow rapidly if conditions are correct
Some can change into spores to keep from dying
when they don’t have enough food
Some make toxins in food as they grow and die

Major Foodborne Bacteria
Bacillus cereus
Listeria monocytogenes
Shiga toxin-producing E. coli
Campylobacter jejuni
Clostridium perfringens
Clostridium botulinum
Nontyphoidal Salmonella
Shigella spp.
Staphylococcus aureus
Vibrio vulnificus
Controlling time and temperature can keep these bacteria from
causing a foodborne illness:
Bacillus cereus
Listeria monocytogenes
Shiga toxin-producing E. coli
Campylobacter jejuni
Clostridium perfringens
Clostridium botulinum
Bacteria: Bacillus cereus (Diarrhea Illness)

Bacteria: Shiga toxin-producing Escherichia
coli, also known as E. coli,
