7.1 Cleaning and disinfection
Cleaning removes visible dirt, debris, grease and waste, commonly with suitable water and detergent. Disinfection is a separate controlled process to reduce harmful microorganisms. Detergent does not usually provide the intended bacteria-and-virus reduction required by a disinfection step.
A visibly soiled surface can prevent disinfectant working properly. The raw-chicken-board example requires removing debris and grease before the suitable disinfectant and its required contact time. A quick spray and wipe may not complete the process even if the board looks better.
The source explains that a combined sanitiser may need two stages: first cleaning away soil, then applying it again to disinfect the cleaned surface. Follow the actual suitable product instructions; the word sanitiser does not guarantee that a single rushed application achieves both functions.
When a raw-meat worktop becomes a sandwich-preparation area, complete the required method before ready-to-eat work. The closing distinction is useful: cleaning removes dirt and disinfection controls germs. Use the necessary steps for the task rather than treating clean appearance as evidence of safety.
7.2 Food-contact surfaces and equipment
Worktops, boards, knives, probes, trays, containers, mixers, slicers, tongs, spoons and display equipment directly touch food. Keep them suitably clean and disinfected, especially after a raw task and before ready-to-eat use. A quick cloth wipe does not establish that a raw-chicken board is suitable for bread, salad or cooked meat.
A probe used in raw or undercooked food can transfer contamination to cooked food if reused unchanged. Apply the correct cleaning and disinfection between compatible uses. The checking tool must not itself undermine the control it is meant to verify.
The schedule should state what is cleaned, when, which product, the method and the responsible person. Record actual completed work only. A signature or tick for a missed task hides the risk rather than providing useful evidence.
Report cracks, deep scratches and other damage that makes equipment difficult to clean. Grooves in a board can hold food and germs. The ending directs staff to follow the method and schedule, disinfect where required and avoid dirty equipment on ready-to-eat food.
7.3 Safe cleaning chemical use
Cleaning products can become hazards if unsuitable or incorrectly used. Select the right product for the task and food-contact purpose and follow directions for dilution, contact time and rinsing where required. The source’s test-standard references support selection but do not replace correct use.
Do not mix chemicals unless the manufacturer gives a safe instruction. Uncontrolled mixing can create dangerous fumes or undermine the product’s effect. Keep containers clearly labelled and safely stored away from food, packaging, utensils and food-contact surfaces.
Never use unmarked or drink bottles for chemicals. The spray-near-open-salad example shows droplets reaching food during a cleaning task; contamination can be created by the very activity intended to protect the kitchen. Protect food and follow the task sequence.
Incorrect strength also matters: too weak may fail to disinfect and too strong may leave harmful residue or taint. Do not improvise a stronger mix to compensate for poor cleaning. The ending combines suitable product, instructed strength and time, safe storage and protection of food.
7.4 Waste and pest warning signs
Waste can attract pests, which contaminate food, packaging, equipment and surfaces. Remove it regularly to suitable strong cleanable bins in good condition, covered where needed and not overflowing. Wash hands after waste handling and keep external areas clean.
Rubbish on the floor, open bins, spills and dirty waste areas can attract rats, mice, flies, cockroaches and birds. Warning signs include droppings, damaged or gnawed packaging, holes, nests, grease marks, footprints, live or dead insects, eggs, webbing, maggots, feathers, damaged goods and unusual smells.
The source dry-store example rejects simply sweeping away droppings and carrying on. Report immediately; nearby food, packaging and surfaces may need assessment, cleaning, disinfection or disposal through the procedure. The concern is possible contamination and pest access, not merely an unpleasant sight.
Prevent access through closed doors, sealed storage, cleaned spills, removed waste, checked deliveries and reports of holes or damage. Staff should not improvise pesticide treatment. The final instruction is to report warning signs promptly and protect food before a hidden risk reaches a customer.
