ServSafe Manager Exam 1 (4) 3 — Questions and Answers
Question 1: What temperature range defines the Temperature Danger Zone for food safety?
- 32°F to 140°F (0°C to 60°C)
- 41°F to 135°F (5°C to 57°C) (Correct answer)
- 50°F to 165°F (10°C to 74°C)
- 38°F to 155°F (3°C to 68°C)
Correct answer: 41°F to 135°F (5°C to 57°C)
The Temperature Danger Zone is 41°F to 135°F (5°C to 57°C). Bacteria grow most rapidly in this range, potentially doubling in number every 20 minutes. Food should spend as little time as possible in this zone.
Question 2: Which biological hazard is most commonly associated with improperly canned low-acid foods?
- Salmonella Typhi
- Clostridium botulinum (Correct answer)
- Norovirus
- Listeria monocytogenes
Correct answer: Clostridium botulinum
Clostridium botulinum thrives in the anaerobic (oxygen-free) environment of improperly home-canned or commercially canned low-acid foods. It produces a deadly neurotoxin that can cause botulism, a life-threatening illness.
Question 3: A food handler who regularly takes antacids is at greater risk from which pathogen?
- Staphylococcus aureus
- Shigella spp.
- Salmonella spp. (Correct answer)
- E. coli O157:H7
Correct answer: Salmonella spp.
Antacids reduce stomach acid, which is one of the body's natural defenses against pathogens like Salmonella. People with reduced stomach acidity are more susceptible to infection from lower doses of the bacteria.
Question 4: What is the minimum concentration for a chlorine sanitizing solution used on food-contact surfaces?
- 10 to 25 ppm
- 50 to 100 ppm (Correct answer)
- 200 to 300 ppm
- 5 to 10 ppm
Correct answer: 50 to 100 ppm
Chlorine sanitizers for food-contact surfaces must be between 50 and 100 ppm. Concentrations below 50 ppm may not effectively kill pathogens, while concentrations above 100 ppm can be toxic and may corrode equipment.
Question 5: An operation receives a shipment of fresh fish. At what maximum temperature must the fish arrive to be accepted?
- 41°F (5°C) (Correct answer)
- 45°F (7°C)
- 32°F (0°C)
- 50°F (10°C)
Correct answer: 41°F (5°C)
Fresh fish must be received at 41°F (5°C) or colder. Fish held above this temperature can rapidly develop dangerous pathogen levels. The receiver should measure the internal temperature with a calibrated thermometer before accepting the shipment.
Question 6: How should a manager respond when a food handler reports a cut on their hand that is bandaged but not covered by a glove?
- Allow the food handler to work if the bandage is waterproof
- Require the food handler to wear a glove over the bandage when handling food (Correct answer)
- Reassign the food handler to dishwashing only
- Send the food handler home for the remainder of the shift
Correct answer: Require the food handler to wear a glove over the bandage when handling food
A bandage alone is not sufficient protection because it can fall into food. The food handler must wear a single-use glove over the bandage to prevent the bandage (and any potential wound contamination) from reaching the food.
