In a food factory, night hygiene cleaning and day cleaning are two different jobs, not two shifts of the same task — night hygiene is the full, validated clean-down of production equipment and the production environment between runs, while day cleaning covers washrooms, offices, canteens and general housekeeping while the site operates. Auditors assessing against BRCGS Food Safety expect to see this distinction reflected in the cleaning schedule, not a single generic rota covering both.
What night hygiene cleaning actually covers
Night hygiene teams work after production stops, breaking down and cleaning food-contact equipment, conveyors, guarding and the production environment — floors, walls, drains — to a validated method before the next production run. This is deep, allergen-and-pathogen-aware cleaning specific to the product being made, not a general tidy-up.
What day cleaning covers instead
Day cleaning runs alongside live production and covers non-production areas and general housekeeping — washrooms, changing rooms, offices, canteens, corridors and communal areas — plus spot cleaning and 'clean as you go' tasks that do not require the line to be stopped.
Why BRCGS treats this as an audit point
BRCGS Food Safety requires cleaning frequency and methods to be based on risk, with procedures in place to ensure cleaning standards are achieved, validated and verified for the intended use of the product or activity — and notes that a simple visual check is less reliable in high-risk and high-care areas than elsewhere on site. A separated, documented night hygiene programme for production areas, distinct from general day cleaning, is how many sites evidence that risk-based approach at audit.
Where the two teams need to hand over cleanly
The point where night hygiene finishes and production restarts — and where day cleaning starts around a live line — needs a clear handover: signed-off clean-down records before restart, and a day cleaning scope that does not stray into food-contact areas the hygiene team is responsible for. Blurring the two is a common finding in poorly-specified cleaning contracts.
