Food Hazards Flashcards
the unintended presence of harmful organisms or substances in food.
Contamination
Any substance in food that can cause illness, injury,or harm.
Hazard
a danger to food safety caused by disease-causing microorganisms such as bacteria, molds, yeasts, viruses, or fungi.
Biological Hazard
a danger to food safety caused by chemical substances, especially cleaning agents, pesticides, and toxic metals.
Chemical Hazards
a danger to food safety caused by particles such as glass chips, metal shavings, bits of wood, or other foreign matter.
Physical Hazard
a substance that causes an allergic reaction.
Allergen
the contamination of raw food items or the plants or animals from which they come, in their natural settings or habitats.
Direct Contamination
the transference of hazardous substances, mainly microorganisms, to food from another food or surface such as equipment, worktables, or hands.
Cross-contamination
diseases, usually either infectious or toxic, caused by agents that enter the body through the ingestion/consumption of contaminated food.
Foodborne Illnesses
An incident where two (2) or more people experience a similar illness after eating a common food.
Foodborne Disease Outbreak
Bacteria that are dangerous when consumed by humans are called
Pathogens
occur when a pathogen produces a toxin(s) while growing in food before it is eaten.
Intoxications
Viruses and parasites do not cause intoxication.
True
caused when viable food pathogens survive through the host’s stomach into the intestine.
Infections
caused by eating food that contains harmful microorganisms that will produce a toxin once inside the human body.
Toxin-mediated infection
The reproduction of bacteria and the increase in the
number of organisms.
Bacterial growth
resting period, where very little
bacterial growth occurs
lag phase
a
period of accelerated bacterial growth
log phase
a period in bacterial growth which lasts until the bacteria
crowd others within their colony, creating
competition for food, space, and moisture.
Stationary phase
negative-growth phase, during
which bacteria die at an accelerated rate.
Decline phase
acidic pH
<7.0
neutral pH
7.0
TDZ
5 - 57C
41 - 135F
applied to
food items that have not been heated to a safe temperature or kept at an improper temperature.
Temperature abuse
A rule of thumb in the
foodservice industry is that bacteria need about __ hrs to grow to high enough numbers to cause illness.
4
Under ideal conditions, bacterial cells can double in number every __ to __ minutes.
15-30

Acidity
Temperature
Time
Oxygen
Moisture
Aw
Water activity
a measure of the amount of water that is not bound to the food and is, therefore,
available for bacterial growth.
Water activity
Disease-causing bacteria can only grow in
food items with an Aw higher than ___.
0.85
They are much smaller than bacteria, require a living host (human, animal) in which to
grow and reproduce. Do not multiply in food. However, a susceptible person can experience an
infection with only a few viral particles consumed.
Viruses
These are microscopic creatures that need to live on or inside a living host to survive. They take
nourishment from their host.
Parasites
These range from single-celled to multicellular organisms which include yeasts, molds, mildews, and
mushrooms. Some are harmless to humans, while some can cause diseases.
Fungi
Soil from badly washed veggies, type of hazard?
Physical
Insect or insect parts, type of hazard?
Physical
2 major sanitation problems when handling and preparing food
- cross-contamination
- TDZ
T where water boils
100 C
212 F
Cooking T range; most disease-causing organisms are killed in a few minutes
74 C and above
165 F and above
Hot food holding T range; bacteria DO NOT MULTIPLY, but most are NOT killed.
57 - 74 C
135 - 165 F
TDZ; bacteria multiply rapidly
5 - 57 C
41 - 135 F
Cold food storage/refrigeration; food is safe for a short period/little bacterial growth
0 - 5 C
32 - 41 F
Water freezes
0 C
32 F
Subfreezing; bacteria do not grow, but most are not killed
-18 - 0 C
0 - 32 F
Freezer storage; bacteria do not grow, but most are not killed - best T for frozen food storage
- 18 C and below
0 F and below
the internal temperature for a food product at which
microorganisms are killed.

COOKED FOOD
BROWN
[Packaging function] Conceal product and its parts and prevent them from spillage and loss, starting from the
packing line through transportation phases until it arrives at the customer’s home.
Containment
[Packaging function] Prevent outside forces like temperature, humidity, contact, and potential hazards from
intervening with the product inside.
Protection
[Packaging function] Keep products in a controlled environment to remain safe for longer use.
Preservation
[Packaging function] Must be convenient to carry, transport, and open while safely maintaining inside items.
Convenience
[Packaging function] Contains data for tracking, product information, and marketing and brand information.
Information
any food product that has been partially or completely prepared or processed by a
manufacturer
Convenience food
a storing method or principle where deliveries or stocks are rotated
to ensure that the old ones are used first. Old stocks are moved out of storage, and new
deliveries are placed first (at the back or last part) in the storage. Then, old stocks are returned
and placed last (in front).
