The temperature danger zone, where bacteria in food can grow, falls between which two temperatures?

• 32°F to 212°F
• 41°F to 135°F (correct answer)
• 45°F to 145°F
• 70°F to 125°F

The FDA Food Code defines the temperature danger zone as 41°F to 135°F; TCS food held in this range supports rapid bacterial growth, so it must be kept cold at 41°F or below or hot at 135°F or above. The range 32°F to 212°F is tempting because those are the freezing and boiling points of water, but the danger zone is about bacterial growth, not the physical states of water.

A cook is preparing chicken breasts on the grill. What minimum internal temperature must the chicken reach before it can be served?

• 145°F
• 155°F
• 165°F (correct answer)
• 175°F

Poultry, including whole and ground chicken and turkey, must reach a minimum internal temperature of 165°F because it carries a high risk of Salmonella. The answer 155°F is the tempting mix-up, but that is the minimum for ground meats like hamburger patties; poultry always requires the higher 165°F standard.

What is the minimum internal cooking temperature for a hamburger patty made from ground beef?

• 145°F
• 155°F (correct answer)
• 165°F
• 135°F

Grinding meat spreads surface bacteria throughout the product, so ground beef must be cooked to 155°F, higher than the 145°F required for a whole-muscle steak. The answer 145°F is tempting because it applies to intact beef steaks and chops, but once the meat is ground, bacteria that were only on the outside end up in the middle, which demands the higher temperature.

A pork chop and a salmon fillet are cooking on the same flat-top. What minimum internal temperature must each reach, held for 15 seconds?

• 145°F (correct answer)
• 135°F
• 155°F
• 165°F

Seafood and whole cuts of pork, beef, veal, and lamb must reach 145°F for 15 seconds under the FDA Food Code. The answer 155°F is the common trap because it applies to ground meats; a whole-muscle chop or intact fish fillet has bacteria only on its surface, so the lower 145°F standard is sufficient.

A large pot of chili has just finished cooking at 165°F and needs to be cooled for tomorrow. What does the first stage of proper cooling require?

• Cooling from 135°F to 41°F within 2 hours
• Cooling from 135°F to 70°F within 4 hours
• Cooling from 70°F to 41°F within 2 hours
• Cooling from 135°F to 70°F within 2 hours (correct answer)

The FDA Food Code two-stage cooling method requires hot TCS food to drop from 135°F to 70°F within 2 hours, then from 70°F to 41°F within 4 more hours (6 hours total). The option ending at 41°F within 2 hours is tempting because it sounds safest, but the Code splits cooling into two stages, and only the first stage — reaching 70°F — must happen in the first 2 hours.

Leftover soup from yesterday is being reheated so it can go into the hot-holding well for service. What temperature must it reach, and how quickly?

• 135°F within 4 hours
• 145°F within 1 hour
• 165°F within 2 hours (correct answer)
• 180°F within 30 minutes

TCS food reheated for hot holding must reach 165°F within 2 hours to kill bacteria that may have grown during storage. The answer 135°F is tempting because that is the hot-holding temperature, but hot holding only prevents growth; reheating must climb all the way to 165°F first to destroy pathogens before the food goes back on the line.

Mashed potatoes are being held on a steam table for lunch service. What is the minimum temperature at which they must be held?

• 120°F
• 135°F (correct answer)
• 155°F
• 165°F

Hot TCS food must be held at 135°F or above to stay out of the temperature danger zone. The answer 165°F is a tempting mix-up because that is the reheating target, but once food has been properly cooked or reheated, holding it at 135°F or above is sufficient to prevent bacterial growth.

A refrigerated display case holds containers of potato salad. At what temperature must the potato salad be kept?

• 41°F or below (correct answer)
• 45°F or below
• 50°F or below
• 60°F or below

Cold TCS food must be held at 41°F or below, the bottom boundary of the temperature danger zone. The answer 45°F is tempting because a few receiving rules (such as shell eggs) allow 45°F on delivery, but for ongoing cold holding the FDA Food Code requires 41°F or below.

Which of the following foods requires time and temperature control for safety (TCS)?

• A whole, uncut cantaloupe
• Dry, uncooked rice
• Sliced cantaloupe (correct answer)
• A commercially bottled vinegar-based dressing

Once a melon is cut, bacteria from the rind can reach the moist, low-acid flesh, so sliced cantaloupe becomes a TCS food that must be held at 41°F or below. The whole, uncut cantaloupe is the tempting distractor because it is the same fruit, but its intact rind protects the interior, so it does not require temperature control until it is cut.

A tray of fried rice is removed from temperature control and held on the counter using time as a public health control. If it is not sold, when must it be thrown away?

• After 1 hour
• After 2 hours
• After 6 hours
• After 4 hours (correct answer)

Hot TCS food held with time as a public health control instead of temperature control must be marked with a discard time and thrown out after a maximum of 4 hours. The answer 6 hours is tempting because cold food may be held up to 6 hours under this rule, but only if it stays at 70°F or below; hot food gets the shorter 4-hour limit.

When checking the internal temperature of a roast chicken with a probe thermometer, where should the probe be inserted?

• Into the thickest part of the meat (correct answer)
• Just under the skin surface
• Into the thinnest part so it reads faster
• Against the bone for a stable reading

The thermometer probe goes into the thickest part of the food because that is the last spot to reach a safe temperature; if the center of the thickest section is done, the rest is too. Checking the thinnest part is tempting because it reads faster, but it cooks first, so a safe reading there can hide an undercooked center elsewhere.

Which of the following is an approved method for thawing a frozen package of ground beef?

• Leaving it on the prep counter overnight
• Placing it in a bowl of hot water
• Setting it near the grill so it thaws quickly
• Submerging it under running potable water at 70°F or below (correct answer)

Approved thawing methods are: in the refrigerator, submerged under running potable water at 70°F or below, in the microwave if cooked immediately after, or as part of the cooking process. A bowl of hot water is the tempting shortcut because it is fast, but it warms the outer layers into the danger zone while the center is still frozen, giving bacteria hours to multiply.

Which of the following is one of the nine major food allergens recognized under U.S. federal law?

• Mustard
• Sesame (correct answer)
• Celery
• Strawberries

The nine major allergens are milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame — sesame was added as the ninth by the FASTER Act, effective 2023. Mustard is the tempting distractor because it is a priority allergen in Canada and the EU, but it is not one of the nine that U.S. law requires to be labeled.

Which of the following is NOT one of the nine major allergens under U.S. federal labeling law?

• Milk
• Soybeans
• Mustard (correct answer)
• Crustacean shellfish

Mustard can trigger allergic reactions and is regulated as a priority allergen in some other countries, but it is not among the nine U.S. major allergens: milk, eggs, fish, crustacean shellfish, tree nuts, peanuts, wheat, soybeans, and sesame. Crustacean shellfish is the tempting pick for some because molluscan shellfish (like oysters) are not on the list, but crustaceans — shrimp, crab, lobster — definitely are.

A guest with a peanut allergy orders a stir-fry. Before preparing it, what must the cook do with the wok and utensils that were just used for a peanut dish?

• Wash, rinse, and sanitize them, then wash hands and change gloves (correct answer)
• Wipe them thoroughly with a dry paper towel
• Rinse them quickly under hot running water
• Heat the wok empty until any residue burns off

Preventing allergen cross-contact requires fully washing, rinsing, and sanitizing all equipment and utensils, plus fresh hands and gloves, before preparing the allergen-free dish. Heating the wok until residue burns off is the tempting option because heat kills bacteria, but allergen proteins are not reliably destroyed by cooking temperatures — physical removal through cleaning is the only safe approach.

A customer tells a food handler she has a severe shellfish allergy and asks whether the gumbo contains shrimp. What should the food handler do?

• Assure her it is probably fine since gumbo is mostly sausage
• Suggest she order it and pick out any shrimp she finds
• Guess based on how the dish usually looks
• Notify the manager or person in charge so the recipe and ingredients can be confirmed (correct answer)

When a guest identifies an allergy, the food handler should involve the manager or person in charge, who can verify the recipe and ingredient labels and ensure the dish is prepared without cross-contact. Suggesting she pick out the shrimp is dangerously tempting because it seems practical, but even trace amounts and cooking liquid left behind can trigger a life-threatening reaction.

A kitchen preps raw chicken and fresh salad vegetables during the same shift. What is the best cutting board practice?

• Use one board and flip it over between tasks
• Use separate, designated cutting boards for raw poultry and for produce (correct answer)
• Use one board but rinse it with hot water between tasks
• Use whichever board is closest, as long as it looks clean

Keeping separate boards — often color-coded — for raw meats and for ready-to-eat produce prevents pathogens like Salmonella from transferring off the poultry board onto vegetables that will never be cooked. Rinsing with hot water is the tempting shortcut, but a rinse does not remove or kill pathogens; only a full wash, rinse, and sanitize does, and dedicated boards remove the risk entirely.

A food handler is assembling turkey sandwiches that will not be cooked further. How should the sliced turkey and bread be handled?

• With bare hands, as long as they were just washed
• With bare hands, if each sandwich takes less than a minute
• With single-use gloves, tongs, or deli sheets (correct answer)
• With bare hands, if hand sanitizer was applied first

Ready-to-eat food must not be touched with bare hands; food handlers must use a barrier such as single-use gloves, tongs, deli tissue, or other utensils because there is no later cooking step to kill anything transferred from skin. Freshly washed bare hands are the tempting answer since handwashing does reduce contamination, but washing cannot remove all pathogens — the Food Code still requires a barrier for ready-to-eat food.

A small kitchen has only one prep table. What is the safest way to prep raw fish and a fruit salad using that table?

• Prep them at different times, washing, rinsing, and sanitizing the table between tasks (correct answer)
• Prep them side by side but keep a few inches between the items
• Prep the fruit first, then the fish, with a quick wipe-down between
• Lay down paper towels under the fish so the table stays clean

When separate prep areas are not available, raw items and ready-to-eat items must be prepped at different times, with a full wash-rinse-sanitize of the surface (and fresh hands and utensils) in between. Prepping the fruit first with a quick wipe seems logical because the fruit is done before the fish arrives, but a wipe-down is not sanitizing, and the order alone does not protect the next ready-to-eat task on that table.

Cross-contamination in a kitchen most commonly happens when pathogens are transferred in which way?

• Through air vents blowing across the kitchen
• Through properly labeled chemical containers
• Through food cooked to the correct temperature
• From raw food to ready-to-eat food via hands, utensils, or surfaces (correct answer)

Cross-contamination typically occurs when pathogens hitch a ride from raw meat, poultry, or seafood to ready-to-eat food on shared hands, cutting boards, knives, cloths, or counters. Air vents are a tempting answer because airborne spread sounds plausible, but foodborne pathogens overwhelmingly move by direct contact and shared surfaces, which is why separation and sanitizing are the core defenses.

A grill cook used tongs to place raw hamburger patties on the grill. The burgers are now done. What should the cook use to move them to the buns?

• The same tongs, since the grill's heat killed any bacteria on the burgers
• A clean, sanitized pair of tongs (correct answer)
• The same tongs, after tapping them on the hot grill surface
• A bare hand, since the burgers are fully cooked

The tongs touched raw ground beef, so they carry pathogens that were never exposed to the full cooking process; a clean, sanitized utensil is required for the cooked burgers. Reusing the same tongs is tempting because the burgers themselves reached a safe temperature, but the contamination is on the tongs, not the meat — the utensil would re-contaminate the cooked patties on contact.

A salad was accidentally topped with croutons, but the guest has a wheat allergy. What must the kitchen do?

• Remove the croutons and re-plate the same salad
• Remove the croutons and add extra toppings to compensate
• Prepare a completely new salad with clean equipment and fresh ingredients (correct answer)
• Brush off any visible crumbs and send the salad back out

Once an allergen touches a dish, invisible protein residue remains even after the visible item is removed, so the only safe fix is remaking the dish from scratch with clean, sanitized equipment. Removing the croutons is the tempting quick fix because the plate then looks allergen-free, but crumbs and protein traces left in the greens can still trigger a serious reaction.

Why can't a fryer that is used for breaded shrimp also be used to cook french fries for a guest with a shellfish allergy?

• Allergen proteins from the shrimp remain in the oil and are not destroyed by cooking heat (correct answer)
• The fries would absorb a fishy taste that guests dislike
• The oil temperature drops too much when shrimp is added
• Shrimp breading makes the oil break down faster

Cooking kills bacteria but does not reliably destroy allergenic proteins, so shrimp proteins in shared fryer oil transfer to anything else cooked in it — this is cross-contact. The flavor-transfer answer is tempting because shared oil does affect taste, but taste is a quality issue; the safety issue is that the allergen itself survives frying temperatures and ends up on the fries.

Which of the following actions creates a cross-contamination risk?

• Storing ready-to-eat deli meats on a shelf above raw pork
• Using color-coded cutting boards for different food types
• Washing hands after handling raw chicken and before touching lettuce
• Using one damp cloth to wipe the raw-meat station and then the salad station (correct answer)

A cloth used at the raw-meat station picks up pathogens and spreads them across every surface it touches next, so carrying it to the salad station contaminates a ready-to-eat area; wiping cloths must stay in sanitizer solution and should be kept to their own areas. Storing deli meats above raw pork is the tempting distractor because it mentions raw meat, but that arrangement is actually correct — ready-to-eat food belongs above raw meat, not below it.

How long should the entire handwashing process take, from wetting hands to drying them?

• At least 5 seconds
• At least 10 seconds
• At least 20 seconds (correct answer)
• At least 60 seconds

The full handwashing procedure — wet, apply soap, scrub, rinse, and dry — should take at least 20 seconds, with the vigorous scrubbing portion lasting 10 to 15 seconds. The answer 10 seconds is the tempting mix-up because that figure refers only to the scrubbing step, not the entire process from start to finish.

After which of the following activities must a food handler wash their hands before touching food again?

• Putting on a clean apron
• Sneezing into a tissue (correct answer)
• Taking a clean pan off the drying rack
• Refilling the paper towel dispenser with a new roll

Sneezing, coughing, or using a tissue contaminates the hands with respiratory droplets, so a full handwash is required before returning to food. Putting on a clean apron is the tempting distractor because it involves getting ready to work, but handling clean garments and clean equipment does not contaminate hands the way body fluids, raw food, trash, or phones do.

Where is a food handler allowed to wash their hands?

• At a designated handwashing sink (correct answer)
• In the food prep sink between prep tasks
• In the first compartment of the three-compartment sink
• At the mop sink in the utility closet

Hands may only be washed at a designated handwashing sink, which must be stocked with soap, warm water, and a means of drying. The food prep sink is the tempting nearby option, but washing hands there would contaminate a sink used for food — prep sinks, warewashing sinks, and mop sinks are each reserved for their own tasks and are off-limits for handwashing.

What must a food handler do immediately before putting on a pair of single-use gloves?

• Apply hand sanitizer to both hands
• Blow into each glove to check for pinholes
• Rinse hands briefly with warm water
• Wash their hands (correct answer)

Gloves are a barrier, not a substitute for clean hands, so a full handwash is required before donning them; dirty hands contaminate the outside of gloves as they are pulled on. Hand sanitizer is the tempting shortcut, but sanitizer may only be used after proper handwashing, never in place of it, because it does not remove soil that shields pathogens.

A food handler is doing one long, continuous prep task with the same gloves. How often must the gloves be changed even if nothing goes wrong?

• At least every 4 hours (correct answer)
• Only when they look dirty
• Every 30 minutes
• Once per shift is enough

During continual use on the same task, single-use gloves must be replaced at least every 4 hours, because pathogens can multiply to unsafe levels on and inside gloves over time; they must also be changed whenever they tear, get contaminated, or the task changes. Changing them only when they look dirty is the tempting answer, but contamination is invisible — appearance is never the standard.

A food handler had several episodes of vomiting last night but feels better this morning. What is the correct course of action?

• Work the register instead of the kitchen for one day
• Come to work but double-glove all shift
• Stay out of the operation until at least 24 hours after symptoms have stopped (correct answer)
• Work normally as long as no fever is present

Vomiting and diarrhea require exclusion from the operation, and the employee may not return until at least 24 hours after symptoms end, because pathogens like norovirus continue shedding after a person feels better. Working the register is the tempting compromise because it avoids food contact, but exclusion for vomiting and diarrhea means staying out of the establishment entirely, not switching stations.

A food handler notices this morning that his skin and eyes look yellow. What should he do?

• Drink extra water and monitor it for a few days
• Report it to his manager immediately and expect to be excluded from work (correct answer)
• Wear gloves for every task until it clears up
• Only report it if he also has a fever

Yellowing of the skin or eyes is jaundice, a possible sign of hepatitis A, and it must be reported to the manager immediately; the employee is excluded from the operation and the manager involves the regulatory authority before he can return. Wearing gloves is the tempting workaround, but hepatitis A spreads easily and gloves are nowhere near sufficient — exclusion is mandatory.

A food handler reports a sore throat accompanied by a fever. Under the FDA Food Code, what happens next in a restaurant serving the general public?

• Nothing, since a sore throat is not a reportable symptom
• The handler is sent home until a doctor's note arrives
• The handler may work with food if they wear a mask
• The handler is restricted from working with or around exposed food (correct answer)

A sore throat with fever requires restriction: the employee may stay in the operation for duties like cleaning dining areas or working the register, but may not work with or around exposed food, clean equipment, utensils, or linens. Sending the handler home entirely is the tempting stricter answer, but full exclusion for this symptom applies only in operations serving a highly susceptible population, such as a hospital or nursing home.

A food handler's doctor calls to say her stool sample tested positive for norovirus, although she currently feels fine. What must she do?

• Report the diagnosis to her manager, who must exclude her from the operation (correct answer)
• Keep working since she has no symptoms
• Work only with packaged foods until the infection clears
• Take a day off and return without telling anyone

A diagnosis with norovirus — like Salmonella Typhi, nontyphoidal Salmonella, Shigella, Shiga toxin-producing E. coli, or hepatitis A — must be reported to the manager, and the food handler is excluded even without symptoms because these pathogens shed in high numbers and spread through food easily. Working with packaged foods is the tempting middle ground, but diagnosed employees must be excluded from the operation, not reassigned.

A cook has an infected cut on her finger. What must she do before she can continue preparing food?

• Rinse the cut with sanitizer solution every hour
• Switch to tasks that only involve cooked food
• Cover the wound with an impermeable bandage and wear a single-use glove over it (correct answer)
• Keep the cut uncovered so it can air out and heal faster

A wound on the hand or finger must be covered with an impermeable cover such as a waterproof bandage or finger cot, and then covered again with a single-use glove, because infected wounds carry Staphylococcus aureus that can transfer to food. Switching to cooked food is the tempting workaround, but staph toxins formed in food are not destroyed by reheating, so the double barrier is required no matter the task.

A food handler wants to keep a drink at his prep station during a long shift. What does the FDA Food Code allow?

• Any drink is fine as long as it is kept below counter level
• An open mug, if it is kept away from the cutting board
• No liquids of any kind anywhere in the kitchen
• A closed container, such as a cup with a lid and straw, handled to prevent contamination (correct answer)

Employees may drink from a closed beverage container — typically a cup with a lid and straw — if it is handled so it cannot contaminate hands, food, equipment, or single-service articles. Banning all liquids is the tempting strict answer, but the Food Code does permit closed drink containers; it is open cups and eating in prep areas that are prohibited.

Which piece of jewelry may a food handler wear on their hands or arms while preparing food?

• A watch with a metal band
• A plain band ring (correct answer)
• A ring with a small stone setting
• A thin charm bracelet

The only jewelry allowed on the hands and arms during food prep is a plain band ring, such as a simple wedding band, because it has no crevices or settings to trap soil and pathogens. The ring with a small stone is the tempting near-miss because it is still a ring, but stones and settings harbor bacteria and can fall into food, so only a completely plain band qualifies.

How must a food handler's fingernails be maintained?

• Kept short and clean, with no false nails or nail polish when handling food (correct answer)
• Any length is fine if gloves are worn at all times
• Trimmed weekly and polished with clear coat only
• Filed to a point so they are easier to clean under

Fingernails must be kept short and clean because long nails trap soil and pathogens and can pierce gloves; false nails and polish are prohibited when working with food unless gloves are worn per the Food Code's limited allowance. "Any length with gloves" is the tempting answer, but long nails tear gloves and make thorough handwashing impossible, so short, clean, natural nails are the baseline requirement.

A three-compartment sink is being used to sanitize dishes with chlorine solution. What concentration should the chlorine sanitizer be?

• 10 to 25 ppm
• 50 to 100 ppm (correct answer)
• 200 to 400 ppm
• 500 to 1,000 ppm

Chlorine sanitizer for food-contact surfaces should be maintained at 50 to 100 ppm, verified with a test kit. The range 200 to 400 ppm is a tempting figure because it resembles common quaternary ammonium label concentrations, but for chlorine that strength is too high — over-concentrated sanitizer can leave toxic residue on surfaces and must be diluted.

When mixing a quaternary ammonium (quat) sanitizer solution, how does a food handler know the correct concentration to use?

• Always mix it to exactly 50 ppm
• Add sanitizer until the water smells strong
• Follow the concentration on the manufacturer's label instructions (correct answer)
• Match whatever concentration the chlorine bottle recommends

Quat sanitizers vary by formula, so the correct concentration is whatever the manufacturer's label specifies (commonly around 200 ppm for many products), confirmed with a quat test kit. "Always 50 ppm" is the tempting answer because 50 to 100 ppm is the chlorine standard, but chlorine figures do not transfer to quats — each chemical follows its own label.

How should a food handler verify that sanitizer solution in a bucket is at the proper concentration?

• Use a sanitizer test kit or test strip (correct answer)
• Check that the water looks slightly cloudy
• Smell the solution for a strong chemical odor
• Feel whether the water is slippery between the fingers

Concentration can only be verified with the appropriate test kit or test strips, which show whether the solution is within the effective range. Smelling for a strong odor is the tempting shortcut, but odor indicates neither the exact strength nor whether the sanitizer has been depleted by soil and use — a solution can smell chemical and still be too weak to sanitize.

In what order are the compartments of a three-compartment sink used when cleaning pots by hand?

• Sanitize, wash, rinse
• Rinse, sanitize, wash
• Wash, rinse, sanitize (correct answer)
• Wash, sanitize, rinse

The sequence is wash in detergent and water at least 110°F, rinse in clean water, then sanitize, followed by air drying. "Wash, sanitize, rinse" is the tempting near-miss, but rinsing after sanitizing would wash the sanitizer off the surface before it finishes its job — the sanitizing step must always come last, with no rinse afterward.

What is the difference between cleaning a prep counter and sanitizing it?

• Cleaning uses hot water while sanitizing uses cold water
• Cleaning removes food and dirt, while sanitizing reduces pathogens on the cleaned surface to safe levels (correct answer)
• They are two words for the same task
• Sanitizing removes grease, while cleaning kills all germs

Cleaning physically removes visible food, soil, and grease; sanitizing then reduces the remaining pathogens to safe levels — and it only works on a surface that has already been cleaned, because soil shields microorganisms from the sanitizer. "Two words for the same task" is the tempting answer in everyday speech, but in food safety they are distinct, sequential steps and both are required.

In a walk-in cooler, on which shelf should raw chicken be stored?

• The top shelf, so drips fall onto sturdier foods
• The middle shelf, between beef and seafood
• Any shelf, as long as it is wrapped
• The bottom shelf, below all other foods (correct answer)

Raw poultry has the highest minimum cooking temperature (165°F), so it goes on the bottom shelf where its juices cannot drip onto anything stored below. "Any shelf, as long as it is wrapped" is the tempting answer because wrapping seems protective, but packaging leaks and tears — the shelf hierarchy is required regardless of how well items appear to be wrapped.

The top-to-bottom order for storing different raw meats in a cooler is based on what?

• Each food's minimum internal cooking temperature (correct answer)
• The size and weight of each package
• The delivery date of each item
• The price of each item, cheapest on top

Raw foods are stacked by minimum internal cooking temperature — ready-to-eat on top, then whole fish and seafood (145°F), whole cuts of beef and pork (145°F), ground meats (155°F), and poultry (165°F) on the bottom — so anything that drips lands only on food that will be cooked hot enough to kill it. Delivery date is the tempting answer because of FIFO, but FIFO governs front-to-back rotation within a shelf, not the vertical order between shelves.

A delivery of canned tomatoes arrives, and the shelf already holds older cases of the same product. Under FIFO, what should the food handler do?

• Stack the new cases in front so they are easier to reach
• Store the new cases on a separate shelf entirely
• Place the new cases behind the older ones so the oldest stock gets used first (correct answer)
• Mix the cases together since canned goods never expire

First In, First Out means new stock goes behind existing stock so the oldest product — first to expire — is always used first. Stacking new cases in front is the tempting time-saver during a busy delivery, but it buries the older stock at the back where it can sit past its use-by date and eventually be served spoiled or wasted.

A refrigerated truck delivers fresh cheese and deli meats. At what temperature should these cold TCS foods be when the operation receives them?

• 32°F or below
• 41°F or below (correct answer)
• 45°F or below
• 50°F or below

Cold TCS food must be received at 41°F or below, the same temperature at which it will be held; anything warmer should be rejected. The answer 45°F is the tempting exception-based choice because shell eggs and live shellfish may be received at 45°F, but the general rule for cold TCS foods like cheese and deli meats is 41°F or below.

Tuna salad was prepared on Monday and stored at 41°F. Including Monday as day one, by the end of which day must it be served or thrown out?

• Wednesday (day 3)
• Friday (day 5)
• Sunday (day 7) (correct answer)
• The following Wednesday (day 10)

Ready-to-eat TCS food held longer than 24 hours must be date-marked and used or discarded within 7 days at 41°F or below, with the preparation day counting as day one — so Monday prep means Sunday is the last day. Friday is the tempting miscalculation, which happens when the prep day is not counted as day one or the 7 days are shortened for safety margin; the Food Code allows the full 7 days.

Where should a container of degreaser and other cleaning chemicals be stored in a food operation?

• On the top shelf of the dry-storage rack, above the flour
• Next to the three-compartment sink, beside the clean dishes
• Under the prep table where they are easy to grab
• In a designated area away from food, equipment, and food-contact surfaces (correct answer)

Chemicals must be stored in a designated area, physically separated from — and never above — food, equipment, utensils, linens, and single-use items, and always in labeled containers. The top shelf above the flour is the tempting answer because high storage sounds out of the way, but chemicals stored above food can drip or spill directly onto it, which is exactly the arrangement the rule prohibits.

How high off the floor must food be stored in a dry-storage room?

• At least 2 inches
• At least 4 inches
• Directly on the floor is fine if the packaging is sealed
• At least 6 inches (correct answer)

Food must be stored at least 6 inches (15 cm) above the floor to protect it from splash, pests, and moisture and to allow cleaning underneath. "Directly on the floor if sealed" is the tempting answer because intact packaging seems protective, but floor contact exposes packaging to contamination, flooding, and pest gnawing, so the 6-inch rule applies regardless of the wrapper.

Between uses during service, where should wet wiping cloths be kept?

• Draped over the edge of the prep sink to dry
• Submerged in a bucket of fresh sanitizer solution (correct answer)
• Folded neatly next to the cutting board
• In the food handler's apron pocket for quick access

Wet wiping cloths must be held in sanitizer solution at the proper concentration between uses so bacteria picked up from surfaces cannot multiply on the damp fabric. Folding the cloth next to the cutting board is the tempting convenience, but a damp cloth left at room temperature becomes a bacteria reservoir that re-contaminates every surface it wipes.
