FOOD SAFETY 1-4 Flashcards
When does limiting foodborne hazards start
Choosing Wholesalers
HACCP
Hazard Analysis Critical Control Points
HACCP Steps
conduct HA, identify CCPs, establish critical limits, set up procedures, establish corrective actions, verify system is working, & record keeping
Most important federal agency regarding food safety
Food and Drug Admin (FDA)
FDA
Regulates most food processing, shipping and manufacturing, issues recalls of potentially dangerous foods, sets labeling standards, and publishes and updates the Food Code (nationwide standard food food safety)
USDA
United States Department of Agriculture
EPA
Environmental Protection Agency
CDC
Center for Disease Control and Prevention
NMFS
NAtional Marine Fisheries Service
OSHA
Occupational Safety and Health Admin
CPSC
Consumer Product Safety Commission
NSF
National Sanitation Foundation
Main cause of food borne disease
Biological hazards
Most common food borne parasites
protozoa, roundworms, and tapeworms
Foodborne parasite that causes most hospitalizations and deaths
Toxoplasma gondii
Roundworms
problem in hogs and can cause trichinosis in humans who consume infected pork; anisakis can be found in fish such as cod and herring
Flatworms
beef, pork, and fish tapeworms and flakes such as live fluke
Protozoa
Giardia lamblia and Cryptosporidium parvum often infect water
Big 5 Foodborne Illnesses
Salmonella, Shigella, Norovirus, Hepatitis A, Shiga Toxin-Producing E. coli
Salmonella
- usually associated with improperly stored and undercooked chicken
- exposure to animal waste
- develops within 12 to 72 hrs
- lasts from 4 to 7 days
- diarrhea, nausea, vomiting, and dehydration
- cause Typhoid fever
- prevention: avoid cross-contaimination
Shigella
- touching genes, swimming in/drinking contaminated water
- develop within 2-3 days of exposure but can occur in as little as a day or as late as a week
- goes away on its own after a few days
- food buffets/barbecues
Norovirus
- extremely contagious
- contagious from first sign to 3 days to 2 weeks from recovery
- viral infection
- stomach bug/flu
If someone becomes ill and vomits or has a diarrheal incident
must create written plan that includes instructions for the use of EPA registered disinfectants
Hepatitis A Virus (HAV)
- viral infection of the liver
- incubation period of 15 to 50 days
- jaundice
- waterborne
- can be killed by heating to 185F for one minute
- must be cleared by medical professional to return to work
E. coli
- Shiga toxin-producing type
- meat and ground meat primary cause
- prevented by proper handling, cooking meat correctly, and holding meat at the correct temperature
- symptoms within 3 to 4 days, can be 1 to 8
Botulism
- neurotoxin
- life-threatening
- canned foods
- prevented by ensuring canned and packaged items are in good condition upon receipt
Biological Contaminant
need water, nutrients, and right temp to survive
TCS Foods
- must be checked with an appropriate temperature measuring device
- cook chill or sous vide must have a verifiable electronic device to monitor time/temp
Egg Transport
- cartons must bear safe handling instructions
- under refrigeration at an ambient temptation of 45F or less
TCS
Time/Temp Control for Safety
Temperature Danger Zone (TDZ)
- optimal temperature range for harmful organisms to grow in food
- 41F to 135F FDA
- 40 to 140F USDA
Six conditions that cause disease-causing bacteria to multiply to harmful levels
food (high protein, moist, slightly acidic), acidity (0-14, 7neutral point), time (10 to 20 min to multiply), temp (41F to 135F), oxygen need (aerobic need, anaerobic don’t), moisture (pathogenic bacteria need aw to be above 0.85)
Top 9 Allergens
Milk, Eggs, Fish, Crustacean shellfish, Tree nuts, Peanuts, Wheat/gluten, Soybean, Sesame
Cold Preservation
bacteria slow down their growth and eventually stop growing the colder food gets
- refrigeration, chilling, freezing
Refrigeration Preservation
34F to 40F
Chilling Preservation
Just below refrigeration, but still above freezing
Freezing Preservation
Turning water from liquid into a solid
Heat Preservation
raising temperature of food high enough to kill spoilage and pathogenic bacteria
- pasteurization, ultra heat treatment (UHT)
- sterilization
- canning
Pasteurization
heating foods up to mild temp momentarily and then cooling them back down immediately
Sterilization
heating foods at high enough temp for long enough time to destroy all organisms
Botulinum Cook
canned foods are heated to 249F for at least 3 minutes
Dehydration
reducing amount of water
Meat should be rejected if
- looks off color
- 41F or over
FIFO
First In/First Out
