Providing Safe Food
Foodborne Illness
Foodborne Illness

Illness carried or transmitted to people
by food
Foodborne-Illness Outbreak

Incident in which two or more people
experience the same illness after eating
the same food

Reasonable Care Defense
The proof that you have done
everything possible to serve safe
food.

This is NEVER a Good Sign!
Populations at High Risk for Foodborne Illness
Higher Risk People

Infants and preschool-age children

Pregnant women

Elderly people

People taking certain medications

People who are seriously ill
1-5
Populations at High Risk for Foodborne Illnesses
--People who consume potentially
hazardous foods or ingredients that
are raw
--People who eat foods that have
not been cooked to the required
minimum internal temperatures
Populations at High Risk for Foodborne Illnesses
--Anyone with weakened
immunities:
Anorexics, Alcoholics, People
with colds
Potentially Hazardous Food
Food Favoring the Rapid Growth of
Microorganisms:
Meat: Beef, Pork,
Lamb
Fish
Cooked Rice,
Beans, or Other
Heat-Treated
Plant Food
Milk and Milk
Products
Eggs (except those
treated to eliminate
Salmonella spp.)
Poultry
Shellfish and
Crustacean

Potentially Hazardous Food
Food Favoring the Rapid Growth of
Microorganisms: continued
Baked
Potatoes
Raw Sprouts and
Sprout Seeds
Synthetic Ingredients,
Such as Textured Soy
Protein in
Meat Alternatives
Untreated Garlic-and-Oil
Mixtures
Tofu or Other
Soy-Protein Food
Sliced Melons
2007: Cut tomatoes and melons must be held at
41° degrees F or lower
2010: Cut greens/lettuce

Glasses
CDC reports that the flu virus, cold germs and
bacteria can remain on glasses from 2 hours to
2 days!
How Food Becomes Unsafe

Time-Temperature Abuse

Cross-Contamination

Poor Personal Hygiene

Purchasing from unsafe sources
1-9
Time-Temperature Abuse
Food has been abused:

Any time it has been allowed to remain
too long at temperatures favorable to the
growth of foodborne microorganisms

Held

Stored

Cooked

Reheated

Cooled
1-10
Cross-Contamination
Cross-contamination occurs when:

Microorganisms are transferred from
one food or surface to another
1-11
Cross-Contamination
•Contaminated
ingredients added to
ready-to-eat foods
•Cooked/ready-to-eat
foods come in
contact with an unclean surface
•Contaminated
to eat foods
food drips on ready
•Food
handler touches
contaminated food then a ready-toeat food
•Dirty
cleaning cloths not cleaned
and sanitized between uses
