5 questions
1.A food worker prepares raw chicken breasts on a cutting board, then immediately uses the same board to slice fresh lettuce for a salad. Which principle of food safety is being violated, and what is the primary risk?
A.Time-temperature abuse, which promotes rapid bacterial multiplication
B.Cross-contamination, which leads to the transfer of pathogens to ready-to-eat foods
C.Physical contamination, which involves the introduction of foreign objects into the product
D.Inadequate sanitization, which fails to remove chemical residues from the preparation surface
2.To control the growth of pathogens, TCS (Time/Temperature Control for Safety) foods must be kept out of the temperature danger zone. If a batch of chili is removed from the stove at 180°F, what is the most scientifically sound procedure for cooling it to 41°F or lower?
A.Place the hot pot directly into a walk-in refrigerator to ensure rapid ambient cooling
B.Leave the chili at room temperature until it reaches 70°F before moving it to the refrigerator
C.Divide the chili into shallow pans and use an ice-water bath to facilitate heat transfer
D.Cover the pot tightly to prevent moisture loss and place it on the counter for two hours
3.Which of the following scenarios describes the most effective application of proper handwashing protocol as defined by food safety standards?
A.Scrubbing hands and arms vigorously with soap for at least 10 seconds before rinsing under cold water
B.Using an alcohol-based hand sanitizer immediately after handling raw meat to eliminate all biological hazards
C.Washing hands for a total of 20 seconds, ensuring the scrub phase lasts at least 10 to 15 seconds with warm water
D.Rinsing hands thoroughly with soap for 5 seconds to remove visible soil before drying with a reusable cloth towel
4.When reheating previously cooked foods, such as a vegetable soup, for hot holding, what is the required minimum internal temperature that must be reached within two hours?
A.135°F
B.145°F
C.155°F
D.165°F
5.A food scientist is analyzing a chemical hazard in a processing plant.
