Definition of CONTAMINATION
the presence of harmful substances in food; substances can be biological, chemical, or physical
Definition of FECAL-ORAL ROUTE
occurs when food handlers do not wash their hands after using the restroom and may contaminate food and surfaces with feces from their fingers
Definition of MICROORGANISMS
small, living organisms that can be seen only through a microscope
Definition of PATHOGENS
harmful microorganisms
4 types of pathogens
1.) bacteria
2.) viruses
3.) parasites
4.) fungi
Big Six
pathogens identified by the FDA as highly contagious
1.) Shigella spp.
2.) Salmonella
3.) Nontyphoidal Salmonella
4.) Shiga toxin-producing E. coli
5.) Hepatitis A
6.) Norovirus
Common symptoms of foodborne illness (6)
diarrhea, vomiting, fever, nausea, abdominal cramps, jaundice
onset time for foodborne illness
dependent on type of foodborne illness; can range from 30 minutes to 6 weeks
basic characteristics of bacteria: LOCATION
found almost anywhere
basic characteristics of bacteria: DETECTION
cannot be seen, smelled, or tasted
basic characteristics of bacteria: GROWTH
FAT TOM (if conditions are correct, numbers grow rapidly)
basic characteristics of bacteria: PREVENTION
control time and temperature
What does FAT TOM stand for?
F- food
A- acidity
T- temperature
T- time
O- oxygen
M- moisture
Salmonella Typhi (Source, Foods Linked, Prevention)
Source: lives only in humans; people with typhoid fever carry bacteria in their bloodstream and intestinal tract
Foods Linked: ready-to-eat food, beverages
Prevention: exclude food handlers who have been diagnosed with an illness caused by Salmonella Typhi; wash hands; cook food to minimum internal temperatures
Nontyphoidal Salmonella (Source, Foods Linked, Prevention)
Source: farm animals
Foods Linked: poultry/eggs, meat, milk/dairy products, produce such as tomatoes, peppers, and cantaloupes
Prevention: cook poultry/eggs to minimum internal temps; prevent cross-contamination between poultry and ready-to-eat foods; exclude food handlers who are vomiting or have diarrhea and have been diagnosed with an illness caused by nontyphoidal salmonella
Shigella spp. (Source, Foods Linked, Prevention)
Source: found in feces of humans with the illness; flies can transfer bacteria from feces to food
Foods Linked: food easily contaminated by hands (e.g. salads that contain TCS foods)
Prevention: exclude food handlers that have diarrhea and people diagnosed with illness caused by Shigella spp.; wash hands; control flies inside and outside the operation
Shiga toxin-producing (Escherichia coli, a.k.a E. coli) (Source, Foods Linked, Prevention)
Source: intestines of cattle, found in infected people
Foods Linked: ground beef (raw and undercooked), contaminated products
Prevention: exclude food handlers who have diarrhea; cook ground beef to minimum internal temperatures; purchase produce from approved reputable suppliers; prevent cross-contamination between raw meat and ready-to-eat foods
Hepatitis A (Source, Foods Linked, Prevention)
Source: found in feces of people infected with it; can contaminate water and many types of food
Foods Linked: ready-to-eat food; shellfish from contaminated water
Prevention: exclude food handlers who have been diagnosed with Hepatitis A; exclude food handlers who have had jaundice for 7 days or less; wash hands; avoid bare-hand contact with ready-to-eat food; purchase shellfish from reputable suppliers
