Food Safety & Sanitation Flashcards

A personal chef is using a quaternary ammonium (quat) sanitizer. The test strip shows the concentration is at 600 ppm. What should the chef do?

Answer: Dilute the solution to the manufacturer's recommended level (typically 200–400 ppm)

Quat sanitizers at excessive concentrations can leave toxic residue on food-contact surfaces and may not sanitize more effectively than recommended levels.

Which pathogen is responsible for the foodborne illness most commonly associated with fried rice syndrome?

Answer: Bacillus cereus

Bacillus cereus produces heat-resistant spores and emetic toxin that survive cooking in starchy foods like rice when improperly cooled.

A chef notices that a can of tomatoes in the client's pantry is severely dented along the seam. What is the appropriate response?

Answer: Discard the can without opening it

Seam dents can compromise the hermetic seal of canned goods, allowing bacteria including C. botulinum to enter or create anaerobic conditions for toxin production.

What is the minimum internal cooking temperature for stuffed pasta dishes containing meat fillings?

Answer: 165°F (74°C)

Stuffed pasta and other dishes combining multiple ingredients (especially poultry or raw meat mixed with starch) must reach 165°F (74°C) for safety.

A personal chef washes hands thoroughly with soap for 10 seconds and rinses. Is this procedure adequate?

Answer: No, proper handwashing requires at least 20 seconds of scrubbing with soap

Effective handwashing requires a minimum of 20 seconds of vigorous scrubbing with soap to physically remove pathogens from the skin.

Scombroid fish poisoning is caused by which of the following?

Answer: Histamine produced by bacterial decomposition in improperly refrigerated fish

Histamine builds up in the muscle tissue of scombroid fish like tuna and mahi-mahi when they are not promptly refrigerated, and cooking does not destroy this toxin.

A chef is preparing a meal for a client who mentions they have a gluten intolerance. Beyond removing gluten-containing ingredients, what additional step is critical?

Answer: Thoroughly cleaning and sanitizing all utensils, surfaces, and equipment used for gluten-containing foods

Even trace amounts of gluten can cause reactions in sensitive individuals, so all surfaces and tools must be thoroughly cleaned and sanitized to prevent cross-contact.
