Food Safety
What this domain tests
Food Safety questions check whether you can apply Food Code–style time and temperature controls to real kitchen scenarios instead of just reciting numbers. Expect TCS (time/temperature control for safety) foods, cooking and holding temperatures, cooling and reheating, date marking, handwashing, and the five leading risk factors behind foodborne illness: food from unsafe sources, inadequate cooking, improper holding, contaminated equipment, and poor personal hygiene. Active managerial control means the person in charge identifies those risks and builds a control into the operation for each one.
Numbers that get tested
- Danger zone: 41°F to 135°F.
- Cold holding at or below 41°F; hot holding at or above 135°F.
- Cooking: poultry and stuffed items 165°F instant; ground meat 155°F for 17 seconds; whole-muscle pork, beef, fish, and eggs 145°F for 15 seconds (with a 3-minute rest for pork and beef).
- Reheating for hot holding: 165°F for 15 seconds within 2 hours.
- Cooling: 135°F to 70°F within 2 hours, then 70°F to 41°F within 4 more hours (6 hours total).
- Date marking: 7 days at 41°F or below, counting the day of preparation as day 1.
Worked example
A pot of chili comes off the stove at 3:00 p.m. reading 158°F. It must hit 70°F by 5:00 p.m. and 41°F by 9:00 p.m. At 5:15 p.m. it is still 82°F. The first cooling stage has failed, and restarting or rapidly reheating does not reset the clock, so the batch is discarded. The reasoning: cooling failures are a classic cause of Clostridium perfringens illness, and the Code treats a failed stage as product you cannot legally serve.
Traps that cost marks
- Reheating to 165°F applies to food held hot, not to the original cooking step for ground meat.
- Measure internal temperature in the thickest part; an oven or ambient gauge is not evidence.
- Bare-hand contact with ready-to-eat food is prohibited, so tongs, deli tissue, or gloves are required.
- A hand sink is for handwashing only - no dumping ice, no rinsing produce.
- Sanitizer strength follows the label; typical ranges are 50–100 ppm chlorine and 200–400 ppm quaternary ammonium, verified with test strips.
