Question 1Foodborne Illness and Food Safety Hazards

Which bacterium is most commonly linked to improperly canned low-acid foods and produces a heat-resistant toxin?

  1. Bacillus cereus
  2. Clostridium botulinum Correct answer.
  3. Campylobacter jejuni
  4. Staphylococcus aureus

Explanation

Clostridium botulinum grows in anaerobic, low-acid environments such as poorly canned or vacuum-packed foods and produces a neurotoxin that is not reliably destroyed by ordinary reheating. Its spores survive boiling, which is why low-acid foods require pressure canning. The other organisms listed are not associated with this canning hazard.

Question 2Foodborne Illness and Food Safety Hazards

A food handler has vomiting and diarrhoea. What is the correct action under food safety rules?

  1. Take medicine and return to the kitchen the same day
  2. Wear gloves and continue preparing food as normal
  3. Work only in the cold store where food is not handled
  4. Report to the manager and stay away from food work until symptom-free for the required period Correct answer.

Explanation

A food handler with vomiting or diarrhoea may shed pathogens such as norovirus and Salmonella and must report the illness to the manager. They should be excluded from food handling until they have been symptom-free for the period set by the local authority. Gloves or moving to another area do not remove the risk of contaminating food or surfaces.

Question 3Foodborne Illness and Food Safety Hazards

Which condition most favours bacterial growth in food?

  1. Vacuum packing with low water activity
  2. Moisture, warmth and a neutral pH Correct answer.
  3. High salt concentration and freezing
  4. Dryness, cold and high acidity

Explanation

Bacteria need moisture, suitable temperature (often between 5 °C and 63 °C) and a favourable pH to multiply rapidly. Foods with these properties are called high-risk foods and require strict temperature control. Dry, cold, acidic, salty or low-water-activity conditions slow or prevent growth.

Question 4Foodborne Illness and Food Safety Hazards

What is the main food safety concern with raw chicken in a kitchen?

  1. Production of mycotoxins during storage
  2. Cross-contamination of ready-to-eat foods with Campylobacter and Salmonella Correct answer.
  3. Growth of Clostridium botulinum in the refrigerator
  4. Formation of histamine from improper thawing

Explanation

Raw poultry commonly carries Campylobacter and Salmonella, which spread through juices, hands, knives and boards. Separate boards and thorough handwashing after handling raw chicken are essential. Mycotoxins, botulinum growth and histamine are associated with other foods and conditions.

Question 5Foodborne Illness and Food Safety Hazards

Which practice best prevents contamination of food by a handler's hands?

  1. Washing hands with soap and warm water after using the toilet and before handling food Correct answer.
  2. Using hand sanitiser instead of washing after handling raw meat
  3. Rinsing hands quickly with cold water only
  4. Wiping hands on a reusable cloth apron

Explanation

Thorough handwashing with soap and warm water removes transient pathogens and is required after toilet use and before food handling. Cold rinsing, sanitiser alone and cloth aprons do not remove grease and soil effectively. Hand hygiene is a core control against faecal-oral pathogens such as norovirus and Salmonella.

Question 6Foodborne Illness and Food Safety Hazards

Which of these is a physical food safety hazard?

  1. A fragment of broken glass in a salad Correct answer.
  2. Salmonella in undercooked eggs
  3. Aflatoxin in mouldy groundnuts
  4. Cleaning chemical residue on a plate

Explanation

Physical hazards are foreign objects such as glass, metal, stones or bone that can injure a consumer. Salmonella is a biological hazard, aflatoxin is a biological toxin, and cleaning chemicals are chemical hazards. Recognising hazard types guides the right control measures.

Question 7Foodborne Illness and Food Safety Hazards

What is the danger zone for food temperature control?

  1. Between -18 °C and 0 °C
  2. Between about 5 °C and 63 °C Correct answer.
  3. Above 75 °C only
  4. Below 5 °C only

Explanation

The danger zone is roughly 5 °C to 63 °C, where bacteria multiply fastest. High-risk foods should be kept below 5 °C or above 63 °C and moved through the danger zone quickly. Freezing and very hot holding are outside the growth range.

Question 8Foodborne Illness and Food Safety Hazards

A cook finds a dented can with a bulging lid in the dry store. What should be done?

  1. Segregate and discard it because it may contain gas-producing bacteria or a damaged seal Correct answer.
  2. Place it in the refrigerator to slow any bacteria
  3. Open it and smell the contents before deciding
  4. Use the contents only in cooked dishes

Explanation

A bulging can suggests gas production, often from Clostridium botulinum, and a damaged seal may have let contamination in. Such cans must never be used, tasted or smelled to judge safety. They should be segregated and discarded according to local waste rules.

Question 9Foodborne Illness and Food Safety Hazards

Which pathogen is most strongly associated with cooked rice left at room temperature?

  1. Vibrio cholerae
  2. Trichinella spiralis
  3. Listeria monocytogenes
  4. Bacillus cereus Correct answer.

Explanation

Bacillus cereus spores survive cooking and germinate when cooked rice cools slowly at room temperature, producing toxins that cause vomiting. Rice should be cooled quickly and refrigerated. Listeria, Vibrio and Trichinella are linked to other foods.

Question 10Foodborne Illness and Food Safety Hazards

A chef uses the same knife to cut raw meat and then slices fruit without cleaning. Which hazard does this create?

  1. A chemical reaction between meat juices and fruit
  2. Formation of mycotoxins in the fruit
  3. Growth of Clostridium botulinum on the knife
  4. Cross-contamination with pathogens from the raw meat Correct answer.

Explanation

Pathogens from raw meat transfer to the fruit via the knife, and the fruit is eaten without a kill step. This is classic cross-contamination. Separate or properly cleaned and sanitised equipment must be used between raw and ready-to-eat foods.

Question 11Foodborne Illness and Food Safety Hazards

Why are eggs and raw egg products a particular concern in food safety?

  1. They support mould growth faster than any other food
  2. They are always contaminated with Listeria
  3. They may carry Salmonella and are often used in dishes that receive little or no cooking Correct answer.
  4. They contain natural toxins that cause vomiting

Explanation

Eggs can be contaminated with Salmonella, and products such as mayonnaise or mousse may not be cooked before eating. Pasteurised egg or thorough cooking reduces the risk. The other statements are not generally true for eggs.

Question 12Foodborne Illness and Food Safety Hazards

A food handler is preparing sandwiches and notices a cut on their finger. What is the correct control?

  1. Only avoid handling the fillings
  2. Cover the wound with a waterproof dressing and, where required, a glove before handling food Correct answer.
  3. Continue working and wash hands more often
  4. Apply a cloth bandage and keep it dry

Explanation

Open wounds can harbour Staphylococcus aureus and other pathogens, so they must be covered with a waterproof, detectable dressing. A glove may be added over the dressing. Cloth bandages are not waterproof and can shed fibres.

Question 13Foodborne Illness and Food Safety Hazards

Which of the following best describes a chemical hazard in food operations?

  1. Cleaning agents stored in unlabelled bottles near food Correct answer.
  2. A parasite in undercooked fish
  3. A piece of wire from a scrubbing brush
  4. Norovirus shed by an infected handler

Explanation

Chemical hazards include cleaning agents, pesticides and unapproved additives that can contaminate food. Unlabelled bottles near food create a serious risk of accidental use. Wire is a physical hazard, while norovirus and parasites are biological hazards.

Question 14Foodborne Illness and Food Safety Hazards

What is the main reason food handlers must not wear jewellery on hands and wrists?

  1. Jewellery changes the pH of food during handling
  2. Jewellery causes cleaning chemicals to become toxic
  3. Jewellery conducts heat from cooking equipment
  4. Jewellery can harbour bacteria and may fall into food as a physical hazard Correct answer.

Explanation

Rings and watches trap dirt and bacteria and can become loose and fall into food. Both biological and physical risks are created. Most food safety standards require removal of hand jewellery except a plain wedding band where permitted.

Question 15Foodborne Illness and Food Safety Hazards

A delivery of frozen fish arrives at 2 °C and partly thawed. What is the appropriate action?

  1. Reject the delivery because frozen food should arrive frozen and at the correct temperature Correct answer.
  2. Accept it and use it first that day
  3. Accept it only if the supplier offers a discount
  4. Accept it and refreeze immediately

Explanation

Frozen deliveries should arrive frozen and show no signs of thawing, because temperature abuse allows bacterial growth and refreezing degrades quality. Partly thawed product at 2 °C indicates a broken cold chain. The correct action is to reject and record the rejection.

Question 16Foodborne Illness and Food Safety Hazards

Which statement correctly describes spores in food safety?

  1. Spores are a type of chemical hazard
  2. Spores are dormant forms that survive cooking and can germinate into toxin-producing bacteria Correct answer.
  3. Spores are toxins produced only by viruses
  4. Spores are killed by refrigeration

Explanation

Bacterial spores such as those of Clostridium and Bacillus resist heat and can germinate when conditions become favourable, producing toxins. This is why cooked foods must be cooled quickly and why low-acid foods need pressure canning. Refrigeration slows germination but does not destroy spores.

Question 17Foodborne Illness and Food Safety Hazards

How should high-risk food be cooled to limit bacterial growth?

  1. Cool from hot to below 5 °C within about 90 minutes using shallow containers and rapid cooling Correct answer.
  2. Add ice directly to the food after two hours
  3. Leave it on the counter overnight to cool naturally
  4. Place a deep, covered pot in the refrigerator and leave it undisturbed

Explanation

Rapid cooling shortens the time food spends in the danger zone. Shallow containers, portioning and rapid methods such as blast chilling help achieve this. Slow cooling on a counter allows bacteria to multiply and produce toxins.

Question 18Foodborne Illness and Food Safety Hazards

A customer reports that a dish tastes bitter and smells of almonds. Which hazard should be investigated?

  1. Histamine from fresh fish
  2. Botulinum toxin from canned beans
  3. Cyanide from improperly prepared bitter cassava or apricot kernels Correct answer.
  4. Aflatoxin from fresh vegetables

Explanation

Bitter cassava and apricot kernels contain cyanogenic compounds that can release cyanide if not properly processed. A bitter taste with an almond-like odour is a recognised warning sign. Botulinum, histamine and aflatoxin are associated with other foods and signs.

Question 19Foodborne Illness and Food Safety Hazards

Which action best reduces the risk of Listeria monocytogenes in a chilled ready-to-eat food operation?

  1. Rely on hand sanitiser alone
  2. Freeze all ready-to-eat foods before service
  3. Keep chilled storage at or below 5 °C and strictly control the shelf life of ready-to-eat products Correct answer.
  4. Store ready-to-eat foods at room temperature to dry them

Explanation

Listeria grows at refrigeration temperatures, so cold-chain control and shelf-life limits are critical. It is also controlled by thorough cleaning and avoidance of cross-contamination from raw foods. Room-temperature storage and freezing before service do not substitute for these controls.

Question 20Foodborne Illness and Food Safety Hazards

A handler is diagnosed with typhoid fever. Which response is most appropriate?

  1. Allow work if gloves are worn
  2. Allow work only with cold foods
  3. Allow work after one dose of antibiotics
  4. Exclude the handler from food work and follow public health advice on clearance before return Correct answer.

Explanation

Typhoid fever is caused by Salmonella Typhi and can be shed for long periods, so exclusion and public health follow-up are essential. Clearance usually requires negative stool samples and medical approval. Gloves, cold foods or partial treatment do not remove the risk.

Question 21Foodborne Illness and Food Safety Hazards

A kitchen operates a cook-chill system. Which combination best controls bacterial hazards in this system?

  1. Cook, hold at 50 °C for several hours and serve
  2. Cook to a validated core temperature, chill rapidly, store below 5 °C and reheat to at least 75 °C before service Correct answer.
  3. Cook gently, cool slowly, store at 10 °C and reheat to 60 °C
  4. Cook, freeze, thaw at room temperature and serve cold

Explanation

Cook-chill relies on a validated heat step, rapid chilling, strict cold storage and thorough reheating to control spore-formers and vegetative pathogens. Each step limits time in the danger zone. Slow cooling, warm holding and room-temperature thawing all allow bacterial growth.

Question 22Foodborne Illness and Food Safety Hazards

Which scenario most clearly demonstrates a breakdown in the food safety management system rather than a single handling error?

  1. Records show the chiller has run above 8 °C for a week with no corrective action taken Correct answer.
  2. A delivery driver arrives late
  3. A cook forgets to wash hands once during a shift
  4. A menu item is unavailable

Explanation

A food safety management system based on HACCP principles requires monitoring and corrective action when limits are exceeded. A week of out-of-limit chiller temperatures without action shows the monitoring and corrective action steps are not working. A single lapse, late delivery or missing menu item does not by itself show a system failure.

Question 23Foodborne Illness and Food Safety Hazards

A caterer prepares a large batch of stew for an outdoor event the next day. Which control best limits toxin production overnight?

  1. Leave the stew in a large pot to cool overnight in a warm kitchen
  2. Add extra salt and leave it covered on the counter
  3. Keep the stew warm at 45 °C until service
  4. Divide into shallow portions, chill rapidly below 5 °C and reheat thoroughly before service Correct answer.

Explanation

Rapid chilling in shallow portions minimises time in the danger zone, and thorough reheating before service provides an additional kill step. Slow cooling in a large pot, warm holding and counter storage all allow bacteria such as Bacillus cereus and Clostridium perfringens to multiply and produce toxins.

Question 24Foodborne Illness and Food Safety Hazards

Which statement about histamine (scombroid) poisoning is correct?

  1. It is destroyed by freezing the fish
  2. It only affects people with fish allergies
  3. It results from bacterial spoilage of fish such as tuna and mackerel and is not destroyed by cooking Correct answer.
  4. It is caused by a virus in shellfish

Explanation

Histamine forms when bacteria decarboxylate histidine in scombroid fish that have been temperature-abused. The toxin is heat-stable, so cooking does not make the fish safe. Rapid chilling of caught fish is the key control.

Question 25Foodborne Illness and Food Safety Hazards

A handler returns to work after gastroenteritis. Which requirement best reflects safe practice before resuming food handling?

  1. Taking anti-diarrhoeal medicine
  2. Symptom-free for one hour
  3. Wearing double gloves for the first shift
  4. Symptom-free for the required period and cleared under the establishment's return-to-work policy Correct answer.

Explanation

Pathogens can be shed after symptoms stop, so return-to-work decisions follow the required symptom-free period and local policy. Some organisms require negative stool samples. Short symptom-free periods, medication or extra gloves are not adequate safeguards.

Question 26Foodborne Illness and Food Safety Hazards

Which bacterium is most commonly linked to undercooked poultry and is a leading cause of bacterial gastroenteritis in food operations?

  1. Clostridium botulinum
  2. Bacillus cereus
  3. Staphylococcus aureus
  4. Campylobacter jejuni Correct answer.

Explanation

Campylobacter jejuni colonises the gut of poultry and frequently contaminates raw chicken meat and juices. Undercooking or cross-contamination from raw poultry to ready-to-eat food is the main route to illness. Thorough cooking and separation of raw poultry from ready-to-eat items control the risk.

Question 27Foodborne Illness and Food Safety Hazards

A handler notices blue-green mould growing on a loaf of bread in the store. Why should the whole loaf be discarded rather than just the visible mould cut away?

  1. Mould on bread only indicates spoilage and never produces toxins
  2. Cutting away mould is acceptable if the bread is then toasted thoroughly
  3. The mould will make the remaining bread taste bitter but is otherwise harmless
  4. Mould hyphae and mycotoxins can extend into bread well beyond the visible surface Correct answer.

Explanation

Moulds grow thread-like hyphae that penetrate deeper than the visible colony, and some species produce mycotoxins that are heat-stable. Soft foods such as bread allow spread throughout the product, so trimming visible mould does not make it safe. The whole item should be discarded.

Question 28Foodborne Illness and Food Safety Hazards

Which control most directly prevents contamination of food by Staphylococcus aureus from a food handler?

  1. Storing food below 5 °C at all times
  2. Covering cuts and washing hands thoroughly before handling food Correct answer.
  3. Cooking food to 75 °C before service
  4. Using separate chopping boards for raw and cooked meat

Explanation

Staphylococcus aureus lives on human skin, in the nose and in infected wounds, and handlers transfer it by touch. Good hand hygiene and covering skin lesions stop the organism reaching food. Temperature and board controls address other hazards but not this handler-to-food route.

Question 29Foodborne Illness and Food Safety Hazards

Which of these best describes a biological food safety hazard?

  1. A piece of metal swarf from a worn slicing blade
  2. A fragment of glass from a broken light fitting
  3. A virus such as norovirus contaminating ready-to-eat shellfish Correct answer.
  4. Cleaning chemical residue left on a food contact surface

Explanation

Biological hazards are living organisms or their products, including bacteria, viruses, parasites and moulds, that can cause illness. Norovirus on shellfish is a clear example of a viral biological hazard. Glass, chemical residue and metal are physical or chemical hazards.

Question 30Foodborne Illness and Food Safety Hazards

A restaurant receives a consignment of vacuum-packed chilled smoked salmon. Which pathogen is of particular concern in this product and why?

  1. Clostridium perfringens, because it requires oxygen to multiply
  2. Listeria monocytogenes, because it grows at refrigeration temperatures and in low-oxygen packaging Correct answer.
  3. Salmonella Typhi, because it survives only in shellfish
  4. Trichinella spiralis, because it is common in farmed fish

Explanation

Listeria monocytogenes is psychrotrophic, meaning it multiplies at chilled temperatures, and it also grows in the low-oxygen environment of vacuum packs. Ready-to-eat chilled foods such as smoked salmon are therefore a recognised risk. Control relies on strict cold chain, shelf-life limits and hygienic processing.

Question 31Foodborne Illness and Food Safety Hazards

A batch of cooked chicken is left in a warm kitchen for four hours before being refrigerated. Which risk has most likely increased?

  1. Development of mycotoxins from mould
  2. Multiplication of norovirus on the chicken surface
  3. Contamination by a physical hazard
  4. Growth of Clostridium perfringens and possible toxin formation Correct answer.

Explanation

Clostridium perfringens spores survive cooking, and slow cooling or warm holding allows the surviving cells to multiply rapidly in the temperature danger zone. Large numbers of the organism can then cause illness when eaten. Rapid cooling and hot holding above 63 °C are the key controls.

Question 32Foodborne Illness and Food Safety Hazards

A food handler develops jaundice and dark urine after several days of fever and fatigue. Which action is required under food safety law and good practice?

  1. Move the handler to washing-up duties only
  2. Exclude the handler from food handling and refer them for medical assessment Correct answer.
  3. Allow the handler to continue if they wear gloves at all times
  4. Restrict the handler to serving customers at the counter

Explanation

Jaundice may indicate hepatitis A or another infectious illness that can be transmitted through food. The handler must be excluded from food handling and referred for medical advice, and the incident reported to the manager. Return to work depends on medical clearance.

Question 33Foodborne Illness and Food Safety Hazards

Which parasite is most associated with raw or undercooked freshwater fish and can cause gastric illness in humans?

  1. Entamoeba histolytica
  2. Giardia lamblia
  3. Anisakis Correct answer.
  4. Cryptosporidium parvum

Explanation

Anisakis is a nematode parasite found in marine and some freshwater fish, and it can cause gastric illness when raw or undercooked fish is eaten. Freezing to the required temperature or thorough cooking kills the larvae. The other parasites are primarily spread by faecal contamination of water or food.

Question 34Foodborne Illness and Food Safety Hazards

A cook prepares a large pot of rice for a buffet and holds it warm for several hours. Which control best limits Bacillus cereus toxin formation?

  1. Keeping the rice covered in a warm cabinet
  2. Cooling the rice rapidly and holding it either above 63 °C or below 5 °C Correct answer.
  3. Adding vinegar to the rice before holding
  4. Reheating the rice once at the end of service

Explanation

Bacillus cereus spores survive cooking and can germinate and produce toxin if cooked rice is held in the danger zone. Rapid cooling and holding outside the danger zone prevent multiplication and toxin formation. Reheating does not destroy the heat-stable toxin once formed.

Question 35Foodborne Illness and Food Safety Hazards

A supplier delivers raw chicken and ready-to-eat salad in the same unsealed crate, with juices from the chicken touching the salad container. Which hazard is the primary concern?

  1. Chemical contamination of the salad from the crate plastic
  2. Cross-contamination of the salad with Campylobacter and Salmonella Correct answer.
  3. Spoilage of the salad from loss of cold air
  4. Physical contamination of the salad from the crate surface

Explanation

Raw poultry juices commonly carry Campylobacter and Salmonella, and contact with ready-to-eat salad introduces these pathogens without any later cooking step to kill them. The delivery should be rejected and the supplier challenged. Separation of raw and ready-to-eat food during transport is a legal requirement.

Question 36Foodborne Illness and Food Safety Hazards

Which statement about hepatitis A transmission in food operations is correct?

  1. It is a bacterial infection treated with antibiotics
  2. It is spread mainly by coughing and sneezing over food
  3. It is destroyed by freezing but not by cooking
  4. It spreads by the faecal-oral route and is often linked to shellfish and ready-to-eat food handled by an infected person Correct answer.

Explanation

Hepatitis A is a virus spread by the faecal-oral route, often through contaminated water, shellfish or ready-to-eat food handled by an infectious person. Good hand hygiene after using the toilet and exclusion of infected handlers are key controls. Cooking to sufficient temperature also inactivates the virus.

Question 37Foodborne Illness and Food Safety Hazards

A manager reviews records and finds that a chilled ready-to-eat product has been stored at 12 °C for two days instead of the specified 5 °C. Which analysis is most appropriate?

  1. Reheat the product to 70 °C and return it to the chilled cabinet
  2. Test a single sample and sell the rest if that sample passes
  3. Treat the product as potentially unsafe, assess Listeria risk and withdraw it from sale Correct answer.
  4. Continue to sell the product because it is within its use-by date

Explanation

Storage above the specified chilled temperature allows psychrotrophic pathogens such as Listeria monocytogenes to multiply, and the risk increases with time. The product should be treated as potentially unsafe, assessed and withdrawn rather than sold. A use-by date does not validate temperature abuse.

Question 38Foodborne Illness and Food Safety Hazards

Which combination best explains why spores make Clostridium botulinum a serious concern in low-acid canned foods?

  1. Spores survive normal cooking, and the anaerobic, low-acid environment allows germination and toxin production Correct answer.
  2. The organism requires oxygen to produce toxin, so open cans are the main risk
  3. The toxin is heat-stable and cannot be destroyed by boiling
  4. Spores are killed by boiling, so only raw foods are affected

Explanation

Clostridium botulinum spores survive ordinary cooking temperatures and germinate in anaerobic, low-acid conditions such as sealed cans. The resulting toxin is extremely potent, which is why commercial canning uses pressure retorting. Boiling destroys the toxin but not the spores.

Question 39Foodborne Illness and Food Safety Hazards

A food business uses a sous-vide process for chilled ready-to-eat meals. Which combination of factors most strongly controls bacterial hazards in this system?

  1. Adding salt at the table before service
  2. Validated time-temperature cooking, rapid chilling, strict cold chain and shelf-life limits Correct answer.
  3. Relying on the use-by date printed by the packaging supplier
  4. Vacuum sealing alone, because oxygen exclusion prevents all bacterial growth

Explanation

Sous-vide creates low-oxygen conditions that favour anaerobic pathogens, so safety depends on a validated cook, rapid chilling, strict cold chain and a validated shelf life. These controls together prevent germination and growth of Clostridium botulinum and Listeria. Vacuum alone cannot be relied on.

Question 40Foodborne Illness and Food Safety Hazards

A food handler reports diarrhoea and vomiting that began 12 hours after eating a meal. Which pathogen is most consistent with this short incubation period?

  1. Staphylococcus aureus Correct answer.
  2. Salmonella Typhi
  3. Listeria monocytogenes
  4. Hepatitis A

Explanation

Staphylococcal food poisoning typically has a short incubation of about one to six hours because pre-formed toxin in the food acts quickly. Symptoms include sudden vomiting and abdominal cramps. Hepatitis A, Listeria and Salmonella Typhi have much longer incubation periods.

Question 41Personal Hygiene and Handwashing

A food handler in a Lagos kitchen must wash their hands. What is the minimum recommended duration for scrubbing hands with soap and water?

  1. 5 seconds
  2. 20 seconds Correct answer.
  3. 1 second
  4. 3 minutes

Explanation

Effective handwashing requires scrubbing with soap for at least 20 seconds, covering palms, backs of hands, between fingers and under nails. Shorter scrubbing does not give soap enough contact time to lift and remove grease and microorganisms. Rinsing under running water and drying with a clean towel or air dryer completes the process.

Question 42Personal Hygiene and Handwashing

Which moment requires a food handler to wash their hands before continuing work?

  1. After changing into a clean apron
  2. After signing a delivery note
  3. After returning from a toilet break Correct answer.
  4. After clocking in at the start of a shift

Explanation

Using the toilet exposes hands to faecal pathogens, so hands must be washed immediately afterwards and before touching food or equipment. This is one of the most important contamination control points in any food premises. Other listed activities do not involve the same direct risk of faecal contamination.

Question 43Personal Hygiene and Handwashing

What should a food handler do with hand jewellery such as rings and wristwatches before preparing food?

  1. Wash them along with the hands
  2. Cover them with a clean glove
  3. Wear them only on the non-dominant hand
  4. Remove them so hands can be cleaned thoroughly Correct answer.

Explanation

Jewellery and watches trap food debris, moisture and bacteria against the skin and make thorough cleaning impossible. Plain wedding bands may be permitted under some local policies, but loose rings, stones and watches should be removed. Gloves do not make contaminated jewellery safe.

Question 44Personal Hygiene and Handwashing

Which action is the correct final step after washing hands at a handwash basin?

  1. Shaking excess water off the hands
  2. Drying hands thoroughly with a clean towel or air dryer Correct answer.
  3. Wiping hands on the apron
  4. Rinsing hands with sanitiser only

Explanation

Thorough drying removes residual moisture that supports microbial survival and transfer. Clean single-use towels or a working air dryer are acceptable. Damp hands transfer microorganisms more readily than dry hands.

Question 45Personal Hygiene and Handwashing

A cook has a small cut on the finger. What is the correct way to manage it before handling food?

  1. Cover it with a waterproof dressing and, where required, a glove Correct answer.
  2. Rinse it with water and continue cooking
  3. Wrap it in a cloth tied around the finger
  4. Leave it uncovered so it can dry in the air

Explanation

Cuts and grazes must be completely covered with a waterproof, detectable dressing to prevent blood and wound bacteria entering food. Where local rules or risk require, a glove over the dressing adds protection. Any dressing must be checked and replaced if it becomes loose or soiled.

Question 46Personal Hygiene and Handwashing

Why must food handlers keep fingernails short and clean?

  1. Long nails make chopping food slower
  2. Short nails are required for wearing gloves
  3. Long nails cause the hands to sweat more
  4. Dirt and bacteria collect under longer nails and are hard to remove Correct answer.

Explanation

The area under fingernails harbours soil, food debris and microorganisms that routine washing may not reach. Short, clean nails reduce this harbourage and make handwashing more effective. Nail polish and artificial nails are generally discouraged because they can chip into food.

Question 47Personal Hygiene and Handwashing

Which facility must be available so food handlers can wash their hands properly?

  1. A bowl of water with a cloth for wiping hands
  2. A bucket of standing water near the prep table
  3. A shared sink also used for washing vegetables
  4. A dedicated basin with running water, soap and a drying method Correct answer.

Explanation

A designated handwash basin supplied with hot and cold running water, soap and a hygienic drying method is required for proper hand hygiene. Handwash basins must not be used for other purposes such as washing produce or equipment. Standing water and shared cloths do not provide clean rinsing or drying.

Question 48Personal Hygiene and Handwashing

When should a food handler use an alcohol-based hand sanitiser?

  1. Instead of washing after handling raw chicken
  2. As an additional step after washing when hands are visibly clean Correct answer.
  3. Instead of washing after using the toilet
  4. On hands that are visibly greasy

Explanation

Hand sanitiser is a supplement to handwashing and works best on visibly clean hands. It is not effective on greasy or heavily soiled hands and cannot replace washing after toilet use or raw food handling. Washing with soap and water remains the primary method.

Question 49Personal Hygiene and Handwashing

A food handler sneezes into their hands while plating a meal. What should they do next?

  1. Apply sanitiser and resume plating
  2. Wash hands thoroughly before touching food or equipment again Correct answer.
  3. Wipe hands on a clean cloth and continue plating
  4. Put on gloves over the hands and continue

Explanation

Sneezing into hands deposits respiratory droplets and microorganisms that can be transferred to food. The handler must step away and wash hands with soap and water before resuming work. Wiping, sanitising alone or gloving over contaminated hands does not remove the contamination.

Question 50Personal Hygiene and Handwashing

Which practice best prevents cross-contamination between raw meat and ready-to-eat food during preparation?

  1. Rinsing gloves with water between tasks
  2. Washing hands and changing gloves after handling raw meat Correct answer.
  3. Using the same gloves for both tasks to save time
  4. Wiping gloves on a cloth before touching ready-to-eat food

Explanation

Hands and gloves that contact raw meat carry pathogens that must not reach ready-to-eat food. Washing hands and changing gloves between raw and ready-to-eat tasks breaks the transfer route. Rinsing or wiping gloves does not reliably remove contamination.
