Lecture 5 Flashcards
Why is protion control important in menu planing?
Consistent nutritional values
Controlling costs
An attractive plate
What defines a portion size?
Weight Size Length Plate look Food guide sizes (old)
What should the master menu include?
Inclusive of therapeutic and texture modification menus
How man known pathogens are there?
31 accounting for 20% of the outbreaks
-remainder of outbreaks are caused by unspecified agents
What are the 3 types of diseases that causes be caused by pathogens?
- Infection: ingestion of live pathogens which colonize and cause damage to intestinal tract
- Intoxication: Pathogens rproduce a toxin within the food, which following ingestion causes illness
- Toxicoinfection: pathogen are ingested and then produce a toxin in the digestive tract that causes illness
Where do bacteria like to grow the most?
Low acid food
Sugar present
Anaerobic/aerobic
Body temp (37C)
What happens to bacteria above 60C and below 4C?
Below 4 inhibits growth
Above 60 the vegetative cells of pathogenic organisms die
What is FATTOM?
Food (nutritients) Acidity (PHF pH between 4.6-7.5) Time (dangers zone) Temp (danger zone) Oxygen Moisture
What is water activity?
Amount of available water in a food
-lower than 0.85 not considered potentially dangerous
What do fungi require to grow?
Nutrients
O2
time to grow
What to protozoa and viruses have in common?
Do not reproduce in food
Only cause infection
Virus: Norovirus, Hep A
What are the 2 routs of transmission of pathogens?
Direct contact
Undirect contact
What is a carrier?
A person who gives off a pathogen disease without being aware that they have the disease because they do not have symptoms
What is accidental contamination?
Via cleaning or sanitizing chemical agents
OR
Excessive use of additives or preservatives
How do you prevent chemical contamination?
Label Chemicals and sanitizing agents (WHMIS)
Store in a location where food is not stored
Purchase chemicals that are not the colour of food
Policies and procedures
Can physical hazard be accidental or purposeful ?
They can be both
What do outbreaks arise from?
Failure in operations and food handling practices
Who is responsible for addressing hazards and what is the process?
Foodservice leaders responsible for:
- designing (plan)
- Implement (do)
- Assess (study)
- Refine (act)
What kind of approach helps foodservice leaders see thee whole picture?
A system approach
What is a risk?
An estimate of the likelihood or probability of occurrence of a hazard
