Cleaning effectively in your business
Guidance on how to clean equipment and surfaces to prevent harmful bacteria from spreading onto food.
Steps for cleaning effectively
You should do the following things:
- Clean and disinfect food areas and equipment between different tasks, especially after handling raw food.
- Clean as you go. If you spill some food, clear it up straight away and clean the surface thoroughly.
- Use cleaning and disinfection products that are suitable for the job and follow the manufacturer’s instructions.
- Disinfection products should meet the BS EN standards. Check product labels for either of these codes: BS EN 1276 or BS EN 13697.
- Do not let food waste build up. Dispose of food waste suitably.
- Use a cleaning schedule to make sure that surfaces and equipment are cleaned when they need to be. It can also help to stop cleaning products being wasted or used incorrectly
Work out what needs cleaning or disinfecting every day, or more than once a day, and what needs cleaning less frequently. Your schedule should show:
- what needs to be cleaned
- what needs to be disinfected
- how often it needs to be done
- how the cleaning/disinfecting should be done
It is a good idea to include cleaning instructions showing:
- cleaning procedures
- what cleaning products should be used
- how the products should be used, including how much they should be diluted and how long they should be left in contact with the surface, following the manufacturer’s instructions
- how the products should be stored - in a special place, not in food areas
Any chemicals used in food establishments to clean and disinfect food contact surfaces and equipment must be approved as food safe. You are advised to follow the manufacturer’s preparation and cleaning instructions. You should pay particular attention to contact times.
Detergents clean the surface and remove grease, but they do not kill bacteria and viruses.
Disinfectants kill bacteria and viruses, and should be used on a visibly clean surface. They do not work effectively if the surface is covered in grease or visible dirt. It is also important that you leave the product on the surface for the time specified in the instructions.
Sanitisers can be used to both clean and disinfect as part of a two-stage approach. First use the sanitiser to clean the surface, removing any:
Re-apply to the visibly clean surface and leave for the required time to disinfect the surface.
If disinfecting products are not available
If the cleaning and disinfecting products you routinely use are not available, you should seek approved, food-safe alternatives with equivalent and effective properties.
Both alcohol-based sanitisers/surface disinfectants (in concentrations of 70-80%) and common disinfectants based on ammonium compounds or chlorine (bleach), can be effective. They can be applied either as a combined detergent-disinfectant solution or when adopting a two-stage approach as a disinfectant following cleaning with a detergent. In either case, food contact surfaces should be washed down with water to prevent chemical contamination of food.
You must ensure:
- the manufacturer’s instructions on use are followed, including using appropriate dilution rates and contact times
- the health and safety of staff is considered, the Health and Safety Executive (HSE) provides guidance on the use of chemicals in the workplace; and
- the suitability of the chemicals for the surfaces to be cleaned and disinfected
Further advice should be sought from your food safety consultant if required.
If alternative disinfectant products are not available, food businesses may wish to consider using heat as a Critical Control Point. Kitchen items such as knives and utensils can be put into a dishwasher, rated for disinfection, or submerged into boiling water. Surfaces can also be steam cleaned.
