Cleaning & Disinfection

What is the difference between cleaning and disinfection?

• AThey mean the same thing
• BOne is more important than the other
• CDisinfection removes visible dirt, while cleaning kills the microorganisms
• DCleaning removes dirt; disinfection kills microorganisms✓

Answer: Cleaning removes visible dirt and food residue. Disinfection kills microorganisms. Both are essential and often done in sequence (two-stage cleaning).

What are the standard colours for chopping boards in UK food businesses?

• ARed (raw meat), yellow (cooked meat), green (salad and fruit), white (bakery and dairy), blue (raw fish)✓
• BAny colour, as long as they're labelled
• CJust one single colour used for every one of the foods
• DRed (raw fish), yellow (raw poultry), green (raw meat), blue (bakery and dairy)

Answer: In the common UK scheme, red is for raw meat, blue for raw fish, yellow for cooked meat, green for salad and fruit, brown for vegetables and white for bakery and dairy. Colour coding is good practice rather than a legal requirement. It helps prevent cross-contamination.

What is the typical six-stage cleaning process?

• AA single wash in cold water with detergent added
• BA single rinse under a hot tap
• CPre-rinse, wash, rinse, disinfect, rinse, dry✓
• DWipe the surface, then spray it with disinfectant and leave

Answer: The six-stage process is: 1) Pre-rinse to remove loose debris, 2) Wash with detergent to remove grease/dirt, 3) Rinse away detergent, 4) Disinfect, 5) Rinse disinfectant, 6) Dry.

What is a 'cleaning schedule' and why is it important?

• AA decorative chart on the wall
• BA documented plan showing what, when, and by whom cleaning is done✓
• COnly important for large businesses
• DA minor administrative detail and nothing more

Answer: A cleaning schedule is a documented plan specifying which areas/equipment need cleaning, how often, and who is responsible. It ensures consistent hygiene.

What should be done before using a cleaning chemical in a food area?

• AUse it straight from the bottle, since all cleaning products sold for kitchens are ready to use
• BCheck the label, follow dilution instructions, and ensure it's food-safe✓
• CTest a small amount on a portion of food to check that it leaves no taste
• DDilute it with far more water than the label states so that it is gentler

Answer: All cleaning chemicals must be checked for food-safe approval, properly diluted according to instructions, and used according to manufacturer guidelines.

How should chopping boards be cleaned after use?

• AJust wipe with a cloth
• BPre-rinse, wash with detergent, rinse, disinfect, rinse, dry (six-stage process)✓
• CSoak them overnight in a clean sink filled with cold water
• DA quick rinse with water

Answer: Chopping boards must undergo the full six-stage cleaning process to remove food debris and kill microorganisms, especially after raw meat use.

What is a 'two-stage cleaning' approach?

• AClean twice daily
• BWet cleaning followed by dry cleaning
• CQuick clean then deep clean
• DCleaning followed by disinfection✓

Answer: Two-stage cleaning is a simplified version of six-stage: Stage 1 (cleaning with detergent to remove dirt), Stage 2 (disinfection to kill organisms).

When should food contact surfaces be cleaned?

• AOnce a week
• BThey do not need cleaning as long as staff change their gloves between each task
• COnce a day
• DBetween different food types, especially before switching to ready-to-eat foods✓

Answer: Food contact surfaces must be cleaned (and disinfected) between different foods, especially when moving from raw to ready-to-eat foods.

What is the purpose of a 'pre-rinse' step in the cleaning process?

• ATo disinfect the surface so that the detergent wash step can be left out
• BTo waste water
• CTo remove loose food debris and reduce cleaning chemical needed✓
• DTo add water

Answer: Pre-rinsing removes loose food debris, making the subsequent wash and disinfection steps more effective and efficient.

How should cleaning equipment (mops, cloths, brushes) be managed to prevent cross-contamination?

• AAssign different colours to different areas; store separately; wash regularly✓
• BUse each mop, cloth and brush until it wears out, then replace it with a new one
• CCleaning equipment needs no management, as detergent kills anything on it
• DUse the same mop and cloths in every area, rinsing them in hot water between rooms

Answer: Cleaning equipment should be colour-coded by area, stored separately, and washed/disinfected regularly to prevent cross-contamination.

What should be followed when using a chemical disinfectant on food preparation surfaces?

• AUse it neat so that it works faster
• BRinse it off immediately, leaving no contact time
• CAny dilution works if the surface is wiped dry
• DThe manufacturer's stated dilution and contact time✓

Answer: Follow the manufacturer's stated dilution and contact time. Too weak or too brief is ineffective; too strong may leave residues.

How should a spill of raw meat blood be managed?

• AClean with detergent, disinfect, rinse, dry; use appropriate PPE; dispose of waste safely✓
• BWipe up and continue
• CWipe with a cloth and spray some sanitiser
• DJust leave it where it is and carry on working close by as normal

Answer: Raw meat spills require: don appropriate gloves/clothing, clean with detergent, disinfect thoroughly, rinse, dry, and dispose of waste in appropriate containers.

What is a 'cleaning record' and why is it important?

• AA nice-to-have document that helps managers plan staff rotas more efficiently
• BA record that only needs to be written up on the day an inspection is announced
• CDocumentation of cleaning activities showing compliance with food safety law✓
• DOptional good practice with no legal force

Answer: Cleaning records document what was cleaned, when, by whom, and how. Records must be proportionate to the size and nature of the business and are the evidence for your food safety procedures and due diligence.

Should cleaning chemicals be stored near food?

• AIn a separate cupboard in the kitchen next to the dry goods
• BYes, provided only small quantities are kept beside the food
• CNo; they must be stored in a separate, locked area✓
• DYes, so they are easy to reach

Answer: Cleaning chemicals must be stored in a separate, locked, secure area away from all food and food contact surfaces.

What should be done if a cleaning chemical is spilled in a food preparation area?

• APour plenty of water over the spill to dilute the chemical, mop the area dry with a kitchen cloth and carry on working
• BReport it; evacuate the area; use appropriate PPE; clean thoroughly; disinfect; and do not use until safe✓
• CWipe it up in the normal way with a disposable cloth, then put the cloth straight into the general kitchen waste bin
• DContinue working around the spill until the end of service, then clean it up during the evening close-down routine

Answer: Any chemical spill requires evacuation, appropriate PPE, thorough decontamination, and the area must not be used for food preparation until verified as safe.

How should high-touch surfaces (door handles, light switches) be cleaned in a food business?

• ARegularly throughout the day, especially high-risk areas✓
• BOnly when they are visibly dirty or marked by customers' hands
• CRoutine cleaning of these can be skipped

Answer: High-touch surfaces should be cleaned and disinfected regularly (multiple times daily) as they're vectors for cross-contamination.

What is the purpose of disinfection testing in a food business?

• APurely a record-keeping exercise
• BTo identify when equipment needs replacing or repairing
• CTo verify that disinfection procedures are effective✓
• DTo improve staff morale by rewarding the best cleaning team

Answer: Testing (e.g., ATP testing, swab testing) verifies that cleaning and disinfection procedures are working effectively to reduce microbial contamination.

Should food preparation areas be cleaned during food service?

• ANo, because cleaning during service disrupts the flow of orders
• BOnly at the end of the day, when the last customers have left
• CCleaning should be carried out only when the premises are closed
