Question 1Food hygiene and sanitation principles

A food handler in a Nairobi hotel kitchen has just finished handling raw chicken and is about to chop vegetables for a salad. What is the most appropriate immediate action?

  1. Wipe hands on a clean kitchen cloth and continue chopping
  2. Wash hands thoroughly with soap and running water before touching the vegetables Correct answer.
  3. Put on a fresh pair of gloves without washing hands first
  4. Rinse hands briefly in the same water used to rinse the chicken

Explanation

Raw poultry commonly carries pathogens such as Salmonella, so hands must be washed with soap under running water after contact with raw meat and before handling ready-to-eat foods. Handwashing physically removes and inactivates contamination that could otherwise transfer to the salad. Gloves or cloths do not substitute for washing because contaminated hands recontaminate them.

Question 2Food hygiene and sanitation principles

Which condition most strongly favours rapid bacterial multiplication in food?

  1. Storage below -18 degrees Celsius in a freezer
  2. Storage in a dry cupboard at 30 degrees Celsius
  3. Storage between 5 and 63 degrees Celsius with available moisture and protein Correct answer.
  4. Storage at 4 degrees Celsius in a refrigerator

Explanation

The temperature range of roughly 5 to 63 degrees Celsius is the danger zone in which bacteria multiply fastest, and moisture plus protein provides the nutrients they need. Foods held in this range for more than about two hours become unsafe. Cold storage below 5 degrees Celsius and freezing slow or stop growth rather than promote it.

Question 3Food hygiene and sanitation principles

A food handler notices a small cut on the finger while preparing sandwiches. What is the correct practice?

  1. Suck the wound clean and keep working without a covering
  2. Wrap the finger in a cloth strip and continue preparing food
  3. Continue working and wash the hand only at the end of the shift
  4. Cover the cut with a waterproof coloured plaster and, where appropriate, a glove, and report it to the supervisor Correct answer.

Explanation

Open wounds can harbour pathogens such as Staphylococcus aureus and can leak into food, so they must be covered with a waterproof, detectable plaster and reported. A glove over the plaster adds protection when handling ready-to-eat food. Reporting allows the supervisor to reassign duties if the wound cannot be properly protected.

Question 4Food hygiene and sanitation principles

Which practice best prevents cross-contamination in a small restaurant kitchen?

  1. Storing raw meat above cooked food in the refrigerator
  2. Using the same chopping board for raw meat and cooked food after a quick wipe
  3. Using separate colour-coded chopping boards and utensils for raw and ready-to-eat foods Correct answer.
  4. Rinsing utensils in a bucket of standing water between tasks

Explanation

Colour-coded equipment creates a physical barrier that stops pathogens from raw foods reaching ready-to-eat foods. Separation of equipment is a core control because bacteria transfer easily via boards, knives and hands. Cleaning alone is less reliable than keeping raw and cooked work physically distinct.

Question 5Food hygiene and sanitation principles

Why must a food handler avoid preparing food while suffering from vomiting and diarrhoea?

  1. Because such illnesses can be caused by pathogens easily transmitted to food and to other people Correct answer.
  2. Because the handler may dislike the smell of certain foods
  3. Because the handler may feel tired and work slowly
  4. Because the handler may need frequent breaks from the kitchen

Explanation

Vomiting and diarrhoea are often caused by organisms such as norovirus and Salmonella that spread through food and hands. A food handler with these symptoms can contaminate food and start an outbreak, so exclusion from food handling is required until symptoms clear. The concern is pathogen transmission, not fatigue or comfort.

Question 6Food hygiene and sanitation principles

Which of the following is a correct way to cool a large pot of cooked stew safely?

  1. Leave it on the stove at room temperature overnight
  2. Add ice directly to the pot and leave it uncovered on the counter
  3. Divide it into shallow containers and refrigerate promptly Correct answer.
  4. Place the covered pot in a warm cupboard until morning

Explanation

Splitting food into shallow containers increases the surface area so the food passes quickly through the danger zone. Prompt refrigeration then keeps it below 5 degrees Celsius. Slow cooling in a large mass allows bacteria to multiply for hours.

Question 7Food hygiene and sanitation principles

What is the main purpose of cleaning and sanitising food contact surfaces?

  1. To remove food residues and reduce microorganisms to a safe level Correct answer.
  2. To remove visible dirt only
  3. To make the surfaces look shiny for customers
  4. To mask unpleasant odours in the kitchen

Explanation

Cleaning removes food residues and grease, while sanitising reduces microorganisms to a level that will not cause illness. Together they prevent pathogens from surviving and transferring to food. Appearance and odour control are side benefits, not the food safety objective.

Question 8Food hygiene and sanitation principles

A food handler is storing a batch of cooked rice for later service. Which practice is safest?

  1. Keep it hot above 63 degrees Celsius or cool it rapidly and refrigerate below 5 degrees Celsius Correct answer.
  2. Store it in a warm oven at 40 degrees Celsius until needed
  3. Cover it and leave it near the cooking area where it stays warm
  4. Hold it at room temperature for up to six hours

Explanation

Cooked rice is a well-known risk food for Bacillus cereus, which multiplies when rice is held warm for long periods. Safe practice is to keep it either hot above 63 degrees Celsius or rapidly cooled and refrigerated below 5 degrees Celsius. The danger zone must be avoided entirely.

Question 9Food hygiene and sanitation principles

Which of the following best describes a pest control requirement for a food premises?

  1. Storing waste in open bins near the kitchen door
  2. Leaving doors open for ventilation so pests can escape
  3. Using food scraps as bait inside the food preparation room
  4. Sealing gaps, fitting screens and keeping waste in closed bins away from food areas Correct answer.

Explanation

Pest control relies on denying pests entry, food and shelter. Sealing gaps, screening openings and using closed bins removes access and attractants. Pests such as rodents and cockroaches carry pathogens and must be excluded from food areas.

Question 10Food hygiene and sanitation principles

A cook must verify that a chicken breast is thoroughly cooked. Which check is most reliable?

  1. Tasting a small piece from the edge of the meat
  2. Measuring the core temperature with a probe thermometer to at least 75 degrees Celsius Correct answer.
  3. Touching the surface to see whether it feels firm
  4. Checking that the outside is browned

Explanation

Core temperature measurement is the reliable way to confirm that pathogens such as Salmonella have been destroyed. Poultry should reach at least 75 degrees Celsius at the thickest part. Surface colour and firmness can be misleading, and tasting raw or partly cooked meat is unsafe.

Question 11Food hygiene and sanitation principles

Why is it important to dry hands with a clean paper towel or hand dryer after washing?

  1. Because wet hands transfer microorganisms more readily and drying removes remaining contamination Correct answer.
  2. Because drying changes the colour of the hands
  3. Because paper towels are required by the supplier
  4. Because wet hands make the soap smell stronger

Explanation

Drying completes hand hygiene because residual moisture helps microorganisms transfer to surfaces and food. Friction with a clean paper towel or the airflow of a dryer removes many organisms left after washing. Reusable damp cloths can recontaminate hands.

Question 12Food hygiene and sanitation principles

A delivery of frozen fish arrives partly thawed with visible ice crystals and soft packaging. What should the food handler do?

  1. Reject the delivery and record the temperature and condition Correct answer.
  2. Accept it and refreeze it immediately
  3. Accept it and store it above cooked foods
  4. Accept it because fish is always safe once cooked

Explanation

Partly thawed frozen food indicates a break in temperature control and possible bacterial growth or quality loss. The safe response is to reject the delivery and record the reason. Refreezing does not undo the risk, and cooking later cannot be assumed to fix all problems.

Question 13Food hygiene and sanitation principles

Which statement about food handler clothing is correct?

  1. Long false nails are acceptable if painted brightly
  2. Clean protective clothing should be worn and jewellery on hands and arms removed Correct answer.
  3. Aprons should be worn until visibly dirty at the end of the week
  4. Jewellery and watches may be worn if they are expensive

Explanation

Clean protective clothing protects food from contamination, and jewellery and watches trap dirt and bacteria and can fall into food. Nails should be short and clean, and aprons should be changed when soiled. These rules apply regardless of the cost of jewellery.

Question 14Food hygiene and sanitation principles

A refrigerator in a food premises is reading 12 degrees Celsius. What is the most appropriate action?

  1. Ignore it because the food still feels cold
  2. Move the food to a working unit, check its temperature and report the fault for repair Correct answer.
  3. Open the door to cool the unit down
  4. Turn the thermostat to its warmest setting

Explanation

A refrigerator at 12 degrees Celsius is above the safe limit of 5 degrees Celsius, so food may have been in the danger zone. The food should be moved to a working unit and assessed, and the fault reported and repaired. Monitoring records help decide whether the food can be kept.

Question 15Food hygiene and sanitation principles

Which statement best explains why food handlers should not smoke or eat in food preparation areas?

  1. They make the kitchen smell unpleasant to customers
  2. They can transfer saliva and microorganisms from hands and mouth to food and create physical contamination Correct answer.
  3. They are only a problem when customers can see them
  4. Smoking and eating reduce productivity during shifts

Explanation

Smoking and eating involve hand-to-mouth contact that transfers saliva and microorganisms to hands and then to food. They also risk physical contamination from ash, cigarette ends and food debris. The risk exists whether or not customers can see the activity.

Question 16Food hygiene and sanitation principles

What does the two-stage cleaning process for a food contact surface usually involve?

  1. Rinsing with cold water only
  2. Wiping with a dry cloth and leaving it
  3. Spraying air freshener over the surface
  4. Cleaning with detergent to remove grease and dirt, then applying a sanitiser Correct answer.

Explanation

Detergent lifts grease and food residues so they can be rinsed away, and the sanitiser then reduces microorganisms on the clean surface. Sanitisers work poorly if dirt or grease remains, so the order matters. A dry cloth or plain water cannot achieve both steps.

Question 17Food hygiene and sanitation principles

A food handler has been diagnosed with typhoid fever. What is the appropriate response under food hygiene principles?

  1. Exclude the handler from food handling and follow medical and public health advice before returning Correct answer.
  2. Allow the handler to work only with cold foods
  3. Allow the handler to work if gloves are worn
  4. Continue working if no symptoms are visible

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 to return to food work depends on medical advice and often negative stool samples. Gloves or working with cold food do not remove the risk.

Question 18Food hygiene and sanitation principles

Which practice is appropriate for storing raw and cooked foods in the same refrigerator?

  1. Place raw meat on the top shelf and cooked food below
  2. Store raw meat uncovered to allow air circulation
  3. Place cooked and raw foods together on the same shelf
  4. Store raw meat below and separate from cooked or ready-to-eat foods, in covered containers Correct answer.

Explanation

Raw meat should be stored below ready-to-eat foods so any drip cannot fall onto food that will not be cooked again. Covered containers add another barrier against cross-contamination. Mixing raw and cooked foods on one shelf defeats this separation.

Question 19Food hygiene and sanitation principles

Which of the following best explains why potable water is required in food preparation?

  1. Water quality affects only the taste of food
  2. Water contacts food, utensils and hands, so contaminated water can introduce pathogens Correct answer.
  3. Water is required only when making drinks
  4. Water is used only for washing floors

Explanation

Water is used for washing produce, utensils, hands and surfaces, so contamination in the supply can spread pathogens widely. Potable water meets microbiological and chemical safety standards. Taste is a minor consideration compared with the risk of illness.

Question 20Food hygiene and sanitation principles

A street food vendor is setting up a stall. Which arrangement best protects the food?

  1. Wash hands in the same bowl used for utensils
  2. Display food openly so customers can see it
  3. Place cooked food next to a bin and a handwashing basin
  4. Keep food covered and elevated, with separate areas for waste and handwashing away from food Correct answer.

Explanation

Covered and elevated food is protected from dust, flies and splashes. Waste and handwashing areas must be kept away from food to prevent contamination. Open display and shared washing water create direct contamination risks.

Question 21Food hygiene and sanitation principles

Why is it important to keep a record of refrigerator and freezer temperatures?

  1. To satisfy staff who enjoy writing
  2. To provide evidence of temperature control and detect faults before food becomes unsafe Correct answer.
  3. To measure how much electricity is used
  4. To decide which foods to order next week

Explanation

Temperature records show that cold storage was maintained and help identify a fault early, before food is put at risk. They also support decisions on whether food is safe after a breakdown. The purpose is verification and early warning, not administration for its own sake.

Question 22Food hygiene and sanitation principles

A kitchen uses a single probe thermometer for raw meat and cooked food. What is the essential practice between uses?

  1. Wipe the probe on the apron
  2. Clean and sanitise the probe before and after each use Correct answer.
  3. Rinse the probe in the cooking pot
  4. Use the probe only for raw meat

Explanation

A probe that has touched raw meat carries pathogens and can contaminate cooked food if not cleaned and sanitised. Cleaning and sanitising before and after each use prevents cross-contamination. An apron or shared pot water can transfer bacteria rather than remove them.

Question 23Food hygiene and sanitation principles

A cook prepares a large batch of meat sauce and plans to serve it over several hours. Which control is essential?

  1. Hold it hot at 63 degrees Celsius or above, or cool and reheat it rapidly to 75 degrees Celsius before service Correct answer.
  2. Add more salt so bacteria cannot grow
  3. Leave it on the counter and reheat portions as needed
  4. Hold it at 40 degrees Celsius and stir occasionally

Explanation

Food held for service must stay outside the danger zone, either hot at 63 degrees Celsius or above or rapidly cooled and reheated to 75 degrees Celsius. Holding at 40 degrees Celsius or on the counter allows bacteria to multiply. Salt is not a substitute for temperature control.

Question 24Food hygiene and sanitation principles

A food handler returns to work after two days of diarrhoea and has had no symptoms for 24 hours. What is the most appropriate action before resuming normal duties?

  1. Resume work only if gloves are worn for the whole shift
  2. Resume food handling immediately without telling anyone
  3. Report to the supervisor and follow the premises' return-to-work policy, which may require medical clearance Correct answer.
  4. Resume work only with cold foods

Explanation

Return-to-work decisions for gastrointestinal illness depend on the organism, symptoms and local public health requirements. Reporting to the supervisor ensures the premises' policy is followed and may require medical clearance. Gloves or cold food duties do not replace proper assessment.

Question 25Food hygiene and sanitation principles

Which situation most clearly shows a breakdown in the separation of clean and dirty activities?

  1. A storekeeper records delivery temperatures on arrival
  2. A food handler uses a cloth used to wipe raw meat juices to dry a salad bowl Correct answer.
  3. A cook checks a thermometer reading before serving
  4. A dishwasher loads clean plates into a cupboard

Explanation

Using a cloth contaminated with raw meat juices on a salad bowl transfers pathogens directly to ready-to-eat food. Clean and dirty tasks must use separate equipment and cloths. Recording temperatures and loading clean plates are normal, safe practices.

Question 26Food hygiene and sanitation principles

Which condition do food spoilage bacteria most commonly need in order to multiply rapidly in food?

  1. Strong acidity and freezing temperatures
  2. Moisture, warmth and available nutrients Correct answer.
  3. Dry air and low humidity
  4. Bright light and oxygen

Explanation

Bacteria need moisture, a suitable warm temperature and nutrients to grow quickly. Removing any one of these, for example by drying, chilling or acidifying the food, slows or stops multiplication. Light and dryness are not growth requirements in the same way.

Question 27Food hygiene and sanitation principles

In food hygiene, what does the term contamination mean?

  1. The presence of any harmful or unwanted substance or organism in food Correct answer.
  2. The natural loss of vitamins during long cooking
  3. The intentional addition of approved preservatives
  4. The change in colour of fruit as it ripens

Explanation

Contamination is the introduction or presence of a hazard such as microbes, chemicals, physical objects or allergens in food. It makes food unsafe or unfit even when appearance is normal. Vitamin loss and ripening are quality changes, not contamination.

Question 28Food hygiene and sanitation principles

A food handler in Nairobi has a mild cough and cold but no fever, vomiting or diarrhoea. What is the correct hygiene approach?

  1. Take antibiotics and return to food handling the same day
  2. Stop work for two weeks until every symptom has cleared
  3. Continue all duties without reporting because a cold is not a foodborne illness
  4. Report to the supervisor, avoid handling exposed food where possible and follow strict hand and cough hygiene Correct answer.

Explanation

Minor respiratory illness does not automatically exclude a handler, but it must be reported so duties can be adjusted. Coughing and sneezing spread droplets, so covering the mouth and washing hands are essential. Medical clearance and exclusion decisions rest with the supervisor and health authorities, not the handler alone.

Question 29Food hygiene and sanitation principles

Why must food handlers keep fingernails short and free of nail polish when preparing food?

  1. Dirt and bacteria collect under nails, and polish or false nails can chip into food Correct answer.
  2. Long nails make it harder to grip knives safely
  3. Short nails are required for wearing gloves
  4. Nail polish reacts chemically with cooking oil

Explanation

The area under fingernails harbours dirt and bacteria that ordinary hand washing may not remove. Chipped polish and false nails are physical hazards that can fall into food. The rule therefore targets microbial and physical contamination, not grip or glove use.

Question 30Food hygiene and sanitation principles

Which practice correctly protects ready-to-eat food from cross-contamination during service?

  1. Stacking raw meat above salad in the display chiller
  2. Rinsing the same knife under the tap between raw meat and salad
  3. Wiping the board with a dry cloth after cutting raw chicken
  4. Using separate clean utensils and boards for raw and ready-to-eat items Correct answer.

Explanation

Separate colour-coded or dedicated equipment prevents bacteria from raw food reaching ready-to-eat food. A quick rinse or dry wipe does not remove bacteria from a knife or board. Storing raw meat above ready-to-eat food allows drips to contaminate it.

Question 31Food hygiene and sanitation principles

What is the purpose of a food safety management system based on HACCP principles in a food business?

  1. To replace the need for staff training and cleaning schedules
  2. To guarantee that no customer will ever complain about taste
  3. To identify significant hazards and control them at critical points before food becomes unsafe Correct answer.
  4. To set the selling price of menu items

Explanation

A HACCP-based system systematically identifies hazards, sets controls at critical control points and monitors them. It prevents or reduces food safety failures rather than relying on end-product testing. Training, cleaning and pricing are separate matters.

Question 32Food hygiene and sanitation principles

A food handler has just used the toilet. What is the correct hand hygiene action before returning to food work?

  1. Wash hands with soap and running water, then dry them properly Correct answer.
  2. Rinse hands briefly with water only
  3. Wipe hands on a shared cloth towel
  4. Apply hand sanitiser without washing

Explanation

Toileting is a high-risk activity because faecal organisms can be transferred to hands. Soap and running water physically remove soil and microbes, and proper drying prevents recontamination. Sanitiser alone is ineffective on soiled hands.

Question 33Food hygiene and sanitation principles

Which storage practice keeps dry foods such as rice, maize flour and beans safe?

  1. Keeping them in a warm damp room to prevent cracking
  2. Leaving sacks open so moisture can escape
  3. Storing opened sacks directly on the floor beside the wall
  4. Keeping them in sealed containers in a cool, dry, pest-proof store off the floor Correct answer.

Explanation

Sealed, elevated containers in a cool dry store protect dry foods from moisture, pests and contamination. Direct floor contact invites damp, dirt and rodents, and open sacks allow pest access. Dry foods must stay dry to prevent mould growth.

Question 34Food hygiene and sanitation principles

A caterer is planning a cold buffet that will be displayed for several hours. Which control best limits bacterial growth?

  1. Cover the food with a cloth and check it occasionally
  2. Hold the food below 5 degrees Celsius using monitored refrigeration or an ice bath Correct answer.
  3. Keep the food in a warm room so flavours develop
  4. Add extra salt and leave the food at room temperature

Explanation

Cold holding below 5 degrees Celsius slows bacterial multiplication during display. The temperature must be monitored, and an ice bath is a valid method where mechanical refrigeration is unavailable. Warm rooms and occasional checks allow the food to drift into the danger zone.

Question 35Food hygiene and sanitation principles

Why is it unsafe to thaw frozen chicken on the kitchen counter overnight?

  1. The chicken loses too much water and becomes dry
  2. The outer surfaces warm into the danger zone while the centre stays frozen, allowing bacterial growth Correct answer.
  3. Counter thawing makes the meat cook faster than required
  4. Frozen chicken cannot absorb marinade after counter thawing

Explanation

Thawing at room temperature warms the outside of the food long before the centre defrosts, giving bacteria time to multiply. Safe thawing happens in the refrigerator, under cold running water or during cooking. Quality issues such as dryness are secondary to this microbial risk.

Question 36Food hygiene and sanitation principles

Which temperature range is commonly described as the danger zone for bacterial growth in food?

  1. 5 to 60 degrees Celsius Correct answer.
  2. 0 to 5 degrees Celsius
  3. -18 to 0 degrees Celsius
  4. 60 to 100 degrees Celsius

Explanation

Between about 5 and 60 degrees Celsius, bacteria multiply most rapidly, with the fastest growth near body temperature. Food should be kept either well below 5 or above 60 degrees Celsius. Frozen and chilled ranges slow growth, and cooking temperatures kill many organisms.

Question 37Food hygiene and sanitation principles

A food handler notices a small cut on the hand while preparing sandwiches. What is the correct action?

  1. Cover the cut with a waterproof brightly coloured dressing and, if on the hand, a glove, then continue with clean hands Correct answer.
  2. Continue working and wipe the cut with a cloth if it bleeds
  3. Wash the cut with water and leave it uncovered so air reaches it
  4. Stop all food work permanently and leave the premises

Explanation

A waterproof, detectable dressing stops blood and bacteria from reaching food, and a glove gives extra protection on the hand. Leaving a wound uncovered risks contamination of food and surfaces. Permanent exclusion is unnecessary for a minor covered cut.

Question 38Food hygiene and sanitation principles

What is the main reason food premises are designed with smooth, impervious, easily cleaned wall and floor surfaces?

  1. They keep the kitchen warmer in cold weather
  2. They improve the appearance of the dining room
  3. They prevent soil and microbes from lodging and allow effective cleaning and disinfection Correct answer.
  4. They reduce the cost of building materials

Explanation

Smooth, non-absorbent surfaces leave nowhere for dirt and bacteria to hide and can be washed and disinfected. Cracked or porous surfaces trap soil and moisture. Cost, appearance and warmth are not the hygiene rationale.

Question 39Food hygiene and sanitation principles

Why must waste bins in a food preparation area be kept covered and emptied frequently?

  1. Uncovered bins improve ventilation in the kitchen
  2. Waste attracts pests and supports bacterial growth that can spread to food and surfaces Correct answer.
  3. Frequent emptying reduces the smell of cleaning chemicals
  4. Covered bins are required only for appearance during inspections

Explanation

Food waste provides food and harbourage for pests and a moist medium for bacteria. Covered, regularly emptied bins reduce pest attraction and the risk of contamination spreading to food contact surfaces. Smell control and ventilation are minor side benefits, not the reason.

Question 40Food hygiene and sanitation principles

A cook has just used a probe thermometer to check raw minced meat. What must be done before the probe is used on a cooked dish?

  1. Clean and disinfect the probe, then let it dry before use Correct answer.
  2. Nothing, because the cooked dish will be hot enough to kill bacteria
  3. Wipe the probe on the cook's apron
  4. Rinse the probe in the dish being cooked

Explanation

A probe that touched raw meat carries bacteria that would contaminate cooked or ready-to-eat food. It must be cleaned and disinfected and allowed to dry between uses. Aprons and the food itself are not cleaning agents.

Question 41Food hygiene and sanitation principles

Which statement correctly describes the role of hot holding in a food service operation?

  1. Cooked food held for service must be kept above 60 degrees Celsius and checked regularly Correct answer.
  2. Food can be held at any temperature provided it is covered
  3. Food should be held just below boiling point to keep it tender
  4. Hot holding replaces the need to cook food thoroughly

Explanation

Hot holding above 60 degrees Celsius keeps food out of the danger zone where bacteria multiply. Regular temperature checks confirm the equipment is working. Hot holding does not substitute for thorough cooking, which must happen first.

Question 42Food hygiene and sanitation principles

A food handler must wash hands. Which sequence is correct?

  1. Wet hands, rinse, then apply sanitiser without soap
  2. Wet hands, apply soap, rub all surfaces including between fingers and under nails, rinse, dry Correct answer.
  3. Apply soap to dry hands, rinse briefly, then dry on a cloth
  4. Rub hands with a cloth, then rinse with water

Explanation

Effective hand washing needs water and soap worked over all hand surfaces, followed by thorough rinsing and drying. Rubbing time matters because it lifts soil and microbes. Sanitiser and cloths do not replace the soap-and-water step.

Question 43Food hygiene and sanitation principles

Why should raw and cooked foods be kept physically separate during transport to an event?

  1. Separate containers make loading faster
  2. Cooked food gives off odours that affect raw food
  3. Raw food is heavier and could crush cooked food
  4. Leakage or drips from raw food can contaminate ready-to-eat food that will not be cooked again Correct answer.

Explanation

Raw meat and poultry juices can carry pathogens that would contaminate ready-to-eat food, which will not receive a further kill step. Sealed separate containers prevent leakage and cross-contamination. Speed, weight and odour are not the hygiene reason.

Question 44Food hygiene and sanitation principles

A food business uses a chlorine-based sanitiser on food contact surfaces. What is essential for it to work correctly?

  1. Using it at any strength because stronger is always safer
  2. Mixing it with detergent in the same bucket at all times
  3. Using the correct concentration and contact time on a surface that has already been cleaned Correct answer.
  4. Applying it to heavily soiled surfaces without pre-cleaning

Explanation

Sanitisers work only at the correct dilution and contact time, and soil reduces their effectiveness, so surfaces must be cleaned first. Over-strength solutions can taint food and irritate skin. Mixing with some detergents can inactivate the sanitiser.

Question 45Food hygiene and sanitation principles

A manager reviews why a batch of cooked beans left at room temperature overnight should be discarded rather than reheated and served. Which reasoning is most sound?

  1. Some bacteria may have produced heat-stable toxins that reheating cannot destroy Correct answer.
  2. Reheating always makes beans taste bitter
  3. Beans should never be cooked in advance for any reason
  4. Room temperature improves the flavour but not the safety of beans

Explanation

Prolonged holding in the danger zone allows bacteria such as Bacillus cereus to multiply and form toxins that survive reheating. Because the toxin, not just the live organism, causes illness, reheating does not make the food safe. The precaution applies to time and temperature abuse, not to advance cooking in general.

Question 46Food hygiene and sanitation principles

A small restaurant has one sink used for both hand washing and washing vegetables. Why is this a significant hygiene problem?

  1. The sink will block more quickly with vegetable peel
  2. Hand washing introduces faecal and skin bacteria that can contaminate the food being washed Correct answer.
  3. Vegetables absorb too much water from the tap
  4. Hands washed in the sink remove the natural coating from vegetables

Explanation

A shared sink allows bacteria from hands to reach food that may be eaten raw, and food debris in turn makes hand washing ineffective. Separate hand-wash basins and food preparation sinks are expected in food premises. Blockage and water uptake are not the hygiene concern.

Question 47Food hygiene and sanitation principles

A cook cools a large pot of soup by placing the whole pot in a cold room. The centre remains at 30 degrees Celsius after three hours. What does this indicate?

  1. The soup should be left out to cool faster
  2. The cooling method is inadequate because the food is spending too long in the danger zone Correct answer.
  3. The centre temperature does not matter if the surface is cold
  4. The cold room is working correctly and the soup is safe

Explanation

Large volumes cool slowly, so the centre can stay in the danger zone long enough for bacteria to multiply. Dividing the food into shallow containers or using rapid cooling methods is needed. The centre temperature is exactly what determines safety.

Question 48Food hygiene and sanitation principles

During an inspection, a handler is seen drying a freshly sanitised chopping board with a dirty tea towel. Why does this defeat the sanitising step?

  1. Drying with a towel makes the board warp and crack
  2. The towel re-introduces microbes onto the treated surface, undoing the reduction achieved Correct answer.
  3. The towel removes the sanitiser residue that protects the board
  4. Tea towels are not permitted in kitchens for any purpose

Explanation

Sanitising reduces microbes, but a soiled towel transfers them straight back onto the board. Air drying or using a clean single-use paper towel avoids recontamination. The problem is microbial transfer, not residue removal, warping or a blanket ban on towels.

Question 49Food hygiene and sanitation principles

A food premises has a pest sighting log showing repeated rodent droppings near dry storage. Which response best reflects food hygiene principles?

  1. Investigate and close entry points, remove food and harbourage, and use a licensed pest controller with records kept Correct answer.
  2. Spray insecticide over the food sacks to kill pests on contact
  3. Place traps in the dry store and continue storing open sacks on the floor
  4. Ignore the log because droppings in a store do not affect food

Explanation

Pest control requires eliminating access, food and shelter, backed by professional treatment and documented monitoring. Rodents carry pathogens and contaminate food and packaging. Chemical sprays must never be applied directly to food or food-contact surfaces.

Question 50Food hygiene and sanitation principles

Why is it a problem for a food handler with diarrhoea to take anti-diarrhoeal medication and return to work while symptoms are suppressed?

  1. Anti-diarrhoeal drugs change the taste of food handled
  2. The person may still shed pathogens such as Salmonella or E. coli even when stools are formed Correct answer.
  3. Suppressed diarrhoea causes the skin to shed more bacteria
  4. The medication makes the person too tired to work safely

Explanation

Some enteric pathogens continue to be shed in faeces after symptoms settle, and formed stools do not prove the person is non-infectious. Exclusion and clearance decisions should follow medical advice and public health guidance. Tiredness, taste and skin shedding are not the concern.
