Choosing cleaning chemicals that are safe around food

Being suitable for food-area use (a detergent or sanitiser made for kitchens), used at the right dilution and contact time, rinsed where required so no residue reaches food, and kept from tainting or contaminating food - while also being handled safely for staff under COSHH. A cleaning chemical is safe to use around food when it's suitable for food-area use and used correctly so it doesn't taint or contaminate the food. That means: using products designed for food areas (detergents to remove grease and dirt, and sanitisers - ideally meeting a recognised standard - to kill bacteria); using them correctly, at the right dilution (effective strength) and contact time (long enough for a sanitiser to work); rinsing where the product requires, so no chemical residue is left on food-contact surfaces; and preventing tainting or contamination (keeping strong-smelling or harmful chemicals away from exposed food, storing chemicals apart from food, labelling clearly). Alongside the food-safety side, the chemical must also be safe for the staff using it - COSHH still applies, so it must be handled at the right dilution, with ventilation and PPE as needed. So safe-around-food means suitable, correctly used, rinsed, kept from food, and safely handled. So it's a suitable product used correctly and kept from the food. This is general information, not a substitute for your food safety system. This is general information.

It depends on the product - some sanitisers are no-rinse when used at the correct dilution, others need rinsing off with clean water after their contact time; follow the product instructions, and get the dilution right, so no harmful residue is left on food-contact surfaces. It depends on the product - so follow its instructions. Some sanitisers are formulated to be no-rinse when used at the correct dilution: they're safe to leave to dry, or food-safe in residue at that strength. Others need rinsing off with clean water after their contact time. The product's instructions tell you which, and you should follow them. Two points either way. First, get the dilution right: a no-rinse sanitiser used too strong could leave residue it shouldn't, so the no-rinse claim depends on correct dilution. Second, if rinsing, do it after the contact time (not before, which would cut the sanitiser's working time short) - apply, leave for the stated contact time, then rinse. The underlying principle is that no harmful chemical residue should end up on food-contact surfaces or in food - so where a product needs rinsing, rinse it, and where it's genuinely no-rinse at the right strength, you needn't. So check the product: rinse if it says to, at the right point. So it depends - follow the product instructions. This is general information. This is general information.

Because a sanitiser needs to stay in contact with the surface for a stated time to kill the bacteria - a quick spray-and-wipe doesn't give it time to work, so the surface looks done but isn't sanitised; apply it and leave it for its contact time before wiping or rinsing. Contact time matters because a sanitiser needs to stay in contact with the surface for a stated period to actually kill the bacteria. Killing bacteria isn't instant - the sanitiser chemistry needs time to work on them. So if you spray a sanitiser on and wipe it straight off (a quick spray-and-wipe), you don't give it its contact time, and it doesn't sanitise properly - the surface looks clean and done, but the bacteria haven't been killed. This is a common mistake that quietly defeats the sanitising. So the correct method is: apply the sanitiser, leave it on the surface for its stated contact time (on the product instructions), and only then wipe or rinse. That gives it time to do its job. Contact time works alongside the right dilution - both are needed for a sanitiser to be effective (right strength, enough time). So give the sanitiser its contact time, or it won't work. So because it needs time in contact to kill the bacteria. So because killing bacteria takes the stated contact time. This is general information. This is general information.

Yes - strong-smelling chemicals like some sanitisers, solvents and perfumed cleaners can taint nearby exposed food with their smell or flavour; keep such chemicals away from exposed food, cover or remove food when cleaning near it, and use appropriate ventilation. Yes - cleaning chemicals can taint food. Strong-smelling chemicals (some sanitisers, solvents, perfumed cleaners) can taint nearby exposed food with their smell or flavour, so the food picks up a chemical taste or odour. This is separate from harmful contamination - taint spoils the food's quality and makes it unpleasant or unsaleable, even if not necessarily dangerous. To prevent tainting: keep strong-smelling chemicals away from exposed food; cover or remove exposed food when cleaning near it (so vapours, spray and residue don't reach it); use appropriate ventilation (so fumes clear rather than settling on food); and store chemicals away from food. This is part of the broader duty to keep chemicals from reaching or affecting food - which also covers harmful contamination (chemicals getting into food through spills, spray drift or wrong storage). So yes, chemicals can taint food, and the answer is to separate chemicals from exposed food in use and storage. So yes - keep strong-smelling chemicals away from food. So yes; keep them apart from exposed food. This is general information, not a substitute for your food safety system. This is general information.

Yes - cleaning chemicals are hazardous substances to the staff using them (sanitisers, degreasers and descalers can harm skin, eyes and lungs), so COSHH applies: use them at the right dilution, with ventilation and PPE as needed, stored safely and never mixed - separate from the food-safety duty. Yes - COSHH applies to kitchen cleaning chemicals, because they're hazardous substances to the people using them, quite apart from the food-safety angle. Sanitisers, degreasers, descalers and oven cleaners can harm skin, eyes and lungs: irritation, burns, dermatitis, and fumes - especially when strong (concentrates), or if incompatible chemicals are mixed (mixing bleach with an acid descaler, for example, can release toxic gas). So the chemicals must be handled safely under COSHH: used at the right dilution, with ventilation where they give off fumes, with gloves and eye protection where the COSHH assessment requires, stored safely and kept apart from incompatibles, and never mixed. So whenever you clean around food, two duties run together: food safety (the chemical mustn't harm the food) and COSHH (the chemical mustn't harm the staff). Both apply. The staff-safety side is covered further in the chemical-storage-and-handling and COSHH pages. So yes - COSHH applies to protect the people using the chemicals. So yes; they're hazardous to staff, so COSHH applies. This is general information, not a COSHH assessment. This is general information.

A detergent removes grease and dirt (cleaning), while a sanitiser kills bacteria (sanitising) - they do different jobs, so surfaces often need both (clean first, then sanitise); some products are combined detergent-sanitisers, and sanitisers should meet a recognised standard to be effective. A detergent and a sanitiser do different jobs. A detergent removes grease, dirt and food residue from a surface - it cleans, making the surface visibly clean, but doesn't necessarily kill bacteria. A sanitiser kills bacteria (reduces them to a safe level) - it sanitises, controlling the microorganisms that cause food poisoning, but isn't primarily for removing grease and dirt. So they're complementary: a surface often needs both - cleaning first with a detergent (to remove the grease and dirt, because a sanitiser works poorly on a dirty surface), then sanitising (to kill the bacteria on the now-clean surface). This is the two-stage clean common in food businesses. Some products are combined detergent-sanitisers that do both in one (convenient, but still needing correct use and contact time). For sanitisers, choose ones meeting a recognised standard, so they're proven to kill the relevant bacteria. So the detergent cleans and the sanitiser disinfects - different jobs, often both needed. So a detergent cleans; a sanitiser kills bacteria. This is general information. This is general information.
