Which of these are signs to look for in or on the product, packaging, or boxes? Dampness Fluids or fluid stains Frozen blocks of fluids Frozen liquids Ice crystals Discoloration Dryness All are correct Wrong! Thats right! Food that has been thawed and refrozen may have been time-temperature abused. It’s impossible for you to know if this food has been thawed and refrozen correctly and because this is NOT a common practice you should reject the delivery. 6 / 21 Ice crystals or chunks of frozen liquids can be evidence of thawing and refreezing when found where? At the bottom of cases or boxes In or on the food or its packaging Neither Both Wrong! Thats right! When thawing and refreezing is NOT done in a controlled manner, it is time-temperature abuse. Food items with evidence of this should be rejected. 7 / 21 When can frozen fish in reduced-oxygen packaging (ROP) be removed from its packaging? Before thawing the fish in a cooler Before or soon after thawing under running water Neither Both Wrong! Thats right! 8 / 21 When should frozen fish in reduced-oxygen packaging (ROP) be thawed? When it will be used Before removing it from its package Neither Both Wrong! Thats right! 9 / 21 Remove frozen ROP fish from its package before thawing it in a cooler. When thawing ROP fish under running water, when can it be removed from its package? Before thawing Soon after thawing Neither Both Wrong! Thats right! 10 / 21 Why is it unsafe to thaw frozen food at room temperature? Frozen food may contain live pathogens because freezing does NOT kill them The outer parts of the food will be in the TDZ, and pathogens will begin growing Neither Both Wrong! Thats right! 11 / 21 What are some guidelines for thawing frozen TCS food in a microwave? Food thawed in a microwave must be cooked with conventional equipment like an oven or grill Only thaw food in a microwave if it will be cooked immediately after thawing Neither Both Wrong!

Thats right! 15 / 21 Slacking is gradually (slowly) thawing frozen food in preparation for deep frying. Which is an important guideline to follow when slacking food? Do NOT allow the food temperature to go above 41°F during the slacking process Slacked food should be cooked as soon as it has finished thawing Neither Both Wrong! Thats right! 16 / 21 When thawing frozen food, never let any part of the food go above 41°F for more than four hours. In addition to the time spent thawing, what other time is counted towards this four-hour limit? Cooling Prepping Neither Both Wrong! Thats right! 17 / 21 Why is it unsafe to thaw food at room temperature? Because pathogens grow at room temperature Because room temperature is in the TDZ Neither Both Wrong! Thats right! 18 / 21 Fish in Reduced Oxygen Packaging (ROP) should remain in the package and frozen until used. When it can be removed from the package depends on how it will be thawed. Which is correct? When thawing frozen fish in cold storage, take it out of its package first When thawing frozen fish under running water, take the it out of its package before or soon after Neither Both Wrong!
