Final Flashcards
foodborne illness
a disease transmitted to people by food
foodborne illness outbreak
two or more people have the same symptoms after eating the same food
challenges to food safety
- time
- language and culture
- literacy and education
- pathogens
- unapproved suppliers
- high risk populations
- staff turnover
costs of foodborne illness to an operation
- loss of customers and sales
- loss of reputation
- negative media exposure
- lowered staff morale
- lawsuits and legal fees
- staff missing work
- increased insurance premiums
- staff retraining
costs of foodborne illness to a victim
lost work
medical costs
long term disability
death
contamination
the presence of a harmful substances in food
biological contaminant
-pathogens include certain -viruses -fungi -parasites -bacteria
chemical contaminant
foodservice chemicals can contaminate food if used incorrectly
physical contaminant
foreign objects in food or naturally occuring objects
-fish bones in fillets
how food becomes unsafe
- purchasing food from unsafe sources
- failing to cook food correctly
- holding food at incorrect temperatures
- using contaminated equipment
- practicing poor personal hygiene
time temperature abuse
food has stayed too long at temperatures that are good for the growth of pathogens
cross contamination
pathogens can be transferred from one surface or food to another
TCS food
food requiring time and temperature control for safety
ready to eat food
food that can be eaten without further preparation, washing, or cooking
high risk populations
- preschool age children
- elderly people
- people with compromised immune systems
SOPs
standard operating procedures
microorganisms
small, living organisms that can be seen only through a microscope
four types of pathogens that can contaminate food
viruses
bacteria
parasites
fungi
symptoms of a foodborne illness
diarrhea vomiting fever nausea abdominal cramps jaundice
The Big Five
- shigella spp.
- salmonella typhi
- enterohemorhagic and shiga toxin-producing e.coli
- hepatitis a
- norovirus
bacteria
-single celled living microorganisms that can spoil food and cause foodborne illness
where can bacteria be found
almost anywhere
bacteria can be smelled or tasted
no
bacteria growth
-if conditions are correct, bacteria will grow in rapid numbers
bacteria produce toxins
some
prevention of bacteria
time and temperature control
FAT TOM
what bacteria need to grow
- Food (proteins, carbohydrates, TCS)
- Acidity (little to none, 7.5-4.6 pH)
- temperature (41-135’F)
- time
- oxygen (some)
- moisture (high levels)
water activity
amount of moisture available in food for bacteria growth
four stages of bacterial growth
- lag (introduced)
- log (reproduce)
- stationary (continue to grow until unfavorable conditions)
- death (dying bacteria outnumber growing bacteria)
spores
bacteria change form to keep from dying when they lack nutrients
bacteria prevented through controlling time and temperature
- bacillus cereus
- listeria monocytogenes
- e. coli
- campylobacter jejuni
- clostridium perfringens
- clostridium botulinum
bacteria prevented by preventing cross contamination
