Food-Borne Illness Prevention Flashcards

Which food-borne illness is caused by a toxin produced by Staphylococcus aureus?

Answer: Staphylococcal food poisoning

Staphylococcus aureus produces heat-stable toxins in food. Once the toxin is formed, it cannot be destroyed by reheating, making prevention through proper food handling essential.

How long can it take for symptoms of a food-borne illness to appear after consuming contaminated food?

Answer: From 30 minutes to several weeks depending on the pathogen

Incubation periods vary widely depending on the pathogen. Some toxin-based illnesses like Staphylococcal poisoning can appear within hours, while Hepatitis A may take weeks.

Which of the following is a biological hazard in food?

Answer: Salmonella bacteria in raw chicken

Biological hazards include bacteria, viruses, parasites, and fungi. Salmonella in raw chicken is a biological hazard, while glass and metal are physical hazards and cleaning solution is a chemical hazard.

Under BC FOODSAFE, what is the primary reason for keeping records of food temperatures?

Answer: To demonstrate due diligence in preventing food-borne illness

Keeping temperature logs demonstrates due diligence — proof that the operator took reasonable steps to prevent food-borne illness. This is both a best practice and supports regulatory compliance.

Norovirus is most commonly spread in food service through:

Answer: Contaminated water and infected food handlers

Norovirus is highly contagious and primarily spread through the fecal-oral route. Infected food handlers who do not wash hands properly and contaminated water are the main vectors in food service.

Which population group is at the highest risk for serious complications from food-borne illness?

Answer: Elderly persons, young children, pregnant women, and immunocompromised individuals

The vulnerable population groups (sometimes called YOPI — Young, Old, Pregnant, Immunocompromised) are at significantly higher risk for severe illness and complications from food-borne pathogens.
