HIC Health Inspector Food Safety & Sanitation 2 — Questions and Answers
Question 1: What is the minimum internal cooking temperature required for ground beef patties?
- 145°F (63°C)
- 155°F (68°C)
- 160°F (71°C) (Correct answer)
- 165°F (74°C)
Correct answer: 160°F (71°C)
Ground beef must be cooked to a minimum internal temperature of 160°F (71°C) to destroy pathogens including E. coli O157:H7.
Question 2: Which pathogen is most commonly associated with improperly canned low-acid foods?
- Salmonella typhi
- Listeria monocytogenes
- Clostridium botulinum (Correct answer)
- Staphylococcus aureus
Correct answer: Clostridium botulinum
Clostridium botulinum thrives in the anaerobic, low-acid environment of improperly home-canned vegetables, producing the deadly botulinum toxin.
Question 3: A food establishment uses quaternary ammonium compounds (quats) as a sanitizer. What is the required minimum concentration for a sanitizing solution?
- 50 ppm
- 100 ppm
- 200 ppm (Correct answer)
- 400 ppm
Correct answer: 200 ppm
Quaternary ammonium sanitizers must be maintained at a minimum of 200 ppm to be effective against foodborne pathogens on food-contact surfaces.
Question 4: Under the FDA Food Code, which activity requires a food handler to wash hands AND change gloves immediately?
- Moving from salad prep to dessert prep
- Handling raw poultry then ready-to-eat foods (Correct answer)
- Switching from one cutting board to another
- Taking a beverage break
Correct answer: Handling raw poultry then ready-to-eat foods
Transitioning from raw poultry (a high-risk raw protein) to ready-to-eat foods is a cross-contamination risk requiring immediate handwashing and glove change.
Question 5: What water activity (Aw) level is considered the threshold below which most bacterial pathogens cannot grow?
- 0.70
- 0.75
- 0.85 (Correct answer)
- 0.91
Correct answer: 0.85
Most bacterial pathogens require a water activity above 0.85 to grow; foods with Aw at or below 0.85 are generally considered shelf-stable for pathogen control.
Question 6: A health inspector observes food stored in a walk-in cooler at 48°F. Which corrective action is MOST appropriate?
- Issue a warning and return in 30 days
- Require immediate disposal of all TCS foods
- Require the establishment to lower the temperature to 41°F or below and evaluate food safety (Correct answer)
- Allow continued operation since 48°F is within 10 degrees of the limit
Correct answer: Require the establishment to lower the temperature to 41°F or below and evaluate food safety
The inspector should require immediate temperature correction to 41°F or below and assess whether TCS foods have been temperature-abused beyond safe limits.
Question 7: Which type of foodborne illness is caused by ingesting a pre-formed toxin already present in the food?
- Foodborne infection
- Foodborne intoxication (Correct answer)
- Toxin-mediated infection
- Foodborne infestation
Correct answer: Foodborne intoxication
Foodborne intoxication occurs when a person consumes food containing toxins already produced by bacteria, such as Staphylococcal toxin or botulinum toxin.
