Food Safety & HACCP Principles Flashcards

A sushi restaurant serves raw fish. According to FDA guidelines, which parasite control measure is required for fish served raw or undercooked?

Answer: Freezing the fish to -4°F (-20°C) or below for 7 days, or -31°F (-35°C) for 15 hours

The FDA Food Code requires parasite destruction by freezing fish to -4°F (-20°C) for 7 days or -31°F (-35°C) for 15 hours before serving raw or undercooked.

What does the term 'validation' mean in the context of a HACCP system?

Answer: The process of confirming that the control measures in the HACCP plan are scientifically sound and capable of controlling the identified hazards

Validation confirms — through scientific evidence, expert input, or challenge studies — that the HACCP plan's control measures are capable of achieving food safety objectives before or during implementation.

A food inspector finds that a restaurant is cooling a large pot of beef stew by placing it directly in the walk-in cooler without any other intervention. Why is this a food safety concern?

Answer: Large volumes cool slowly, allowing the product to remain in the temperature danger zone long enough for pathogens to multiply to dangerous levels

Large volumes of hot food placed directly in a cooler cool very slowly, potentially keeping the food in the temperature danger zone (41°F–135°F) for hours and allowing pathogen growth.

Which organism is most commonly associated with improperly canned low-acid foods and produces a heat-stable toxin capable of causing potentially fatal foodborne illness?

Answer: Clostridium botulinum

Clostridium botulinum is an anaerobic spore-forming organism that thrives in improperly canned low-acid foods and produces one of the most potent toxins known.

A food facility performs internal HACCP audits quarterly but has not updated its HACCP plan in three years despite adding two new product lines. What HACCP principle has the facility most likely failed to fulfill?

Answer: Principle 1 — Hazard analysis, because new products introduce new hazards not covered by the existing plan

When new products or processes are added, the hazard analysis must be revisited to identify any new or changed hazards; failing to do so violates the foundation of the HACCP system (Principle 1).

An inspector evaluates a food facility and finds that employees are using the same cutting board for raw meat and vegetables without sanitizing between uses. This most directly violates which food safety concept?

Answer: Cross-contamination prevention, a key principle in controlling biological hazards

Using the same surface for raw meat and ready-to-eat vegetables without sanitizing in between is a direct cross-contamination risk, transferring pathogens like Salmonella to foods that won't be cooked again.

Under the HACCP system, HACCP records serve which critical function beyond regulatory compliance?

Answer: They provide a documented history of process control, enabling traceability and rapid response during a foodborne illness outbreak investigation

HACCP records create a traceable, time-stamped history of process control that allows investigators to quickly identify when and where a failure occurred during a foodborne illness outbreak.
