ServSafe Exam Flashcards
What is a Food borne Illness?
A disease transmitted to people by food
An illness is considered an outbreak when…
2 or more people have the same symptoms from eating the same food;
An investigation is conducted by state/local authorities;
Confirmed by lab analysis
What are the “Challenges to Food Safety”?
Time (limited time can cause safety to suffer);
Language and culture (varied communication and views);
Literacy and education (can make teaching difficult);
Pathogens (ill-causing microorganisms);
Unapproved suppliers (they may not practice adequate food safety themselves);
High-risk customers (numbers are increasing);
Staff turnover (retraining takes time)
What are the “Costs of Foodborne Illness” for the operation?
Loss of customer sales; Loss of reputation; Negative media; Lowered staff morale; Lawsuits and legal fees; Staff missing work; Increased insurance premiums; Staff retraining required

Biological (pathogens);
Chemical (cleaners, sanitizers, polishes);
Physical (foreign objects, can be random or naturally occurring)
What are Pathogens?
Greatest threat to food safety;
Viruses, parasites, fungi, and bacteria;
And some plants, mushrooms, and seafood carry harmful toxins (poisons)
What are the 5 most common food-handling mistakes that make food unsafe?
Purchasing from unsafe sources; Failing to cook correctly; Holding at wrong temps; Using contaminated equipment; Practicing poor personal hygiene
Most food handling mistakes can be related to what 4 factors?
