Food business disinfection

In the food chain, disinfection is a documentation question as much as a hygiene one.

What is different on food premises

On premises in the food chain, disinfection has two extra dimensions that other sites do not have.

First — the treatment itself. Surfaces that come into contact with food have to be rinsed afterwards. Our choice of method and product takes account of the fact that food is handled on the site.

Second — documentation. The business has to be able to show that treatment was carried out: when, at what scope, and with what. That is part of the hygiene plan, and it is exactly what the supervisory authorities check.

ZoneWhat the treatment involves
Food preparation surfacesRinsed after treatment
Storage roomsTreated, with product covered or removed
Chill roomsAgreed separately — temperature affects the method
Ventilation and extractionGrease residue has to be removed first
Staff roomsStandard contact surface treatment
Waste areaOften the main source of trouble

Disinfecting a layer of grease or residue is pointless — the product never reaches the surface underneath it.

Why treatment always starts with cleaning

A disinfectant acts on the surface it touches. If there is a film of grease, flour dust or dried product residue on it, the product stays on that layer and nothing underneath changes. That is why on food premises mechanical cleaning is not a preparatory step but part of the job.

The second reason is that many residues are themselves a growth medium. Grease in extraction ducting, product residue under machine feet, sugar or milk residue in joints — they hold moisture and feed exactly what you are trying to eliminate. If they stay, the result of the treatment is short-lived whatever product is used.

1Extraction and filtersGrease aerosol settles on the filters and at the start of the duct. It is a source of smells and a growth medium at the same time.
2Floor joints and gulliesWhere moisture and organic residue collect, and where daily cleaning reaches least often.
3Under and behind machineryBeneath fridges, ranges and benches — product residue stays there for weeks.
4The waste areaThe commonest permanent source of trouble on the whole site, and the one most often left out of the job.

Documentation

For every treatment carried out we prepare a record stating the date, the scope and the zones treated. Where we work regularly, we keep a log of the work carried out that can be filed with the business's hygiene documentation.

We do not build your HACCP system and we do not sign off compliance — we carry out the treatment and document it so that it can be filed within your own system.

Where responsibility divides

The practical distinction is this: your hygiene plan sets out what has to be done and how often, and that is the business's responsibility. We are a contractor for one part of it, and our record is the evidence that this part was carried out on a given date. If the plan calls for treatment once a quarter but the log shows twice a year, that is a question at inspection — which is exactly why, in an ongoing arrangement, we keep one continuous list of dates rather than separate sheets.

The type of site changes the priorities.

  • A production plant — process surfaces and drains matter most.
  • A bakery or patisserie — flour dust on top of that, settling everywhere including ceiling structures and light fittings.
  • Meat and fish processing — the priority is floor joints, gullies and chill rooms.
  • A small café or shop kitchen — most of the trouble sits in the extraction and the waste area.

So there is no single treatment plan for all food premises — it is built around what actually happens on the site.

When we can work

We work outside production hours: after the last shift, on a non-working day or during a planned stoppage. Treatment during production is not possible, because food handling and disinfection cannot go on in the same space at the same time.

  • Open product and raw materials must be removed or sealed.
  • Packaging materials must be taken out of the zone being treated.
  • Machinery must be switched off and, where necessary, cooled down.
  • Chill rooms are agreed separately — temperature affects how the product works.
  • Time has to be allowed after treatment for rinsing and airing before the next shift.

How we work

Inspection

We assess the zones, how they are used and the production schedule.

Agreeing the timing

We work outside production hours.

Mechanical cleaning

Removing grease and dirt — without it disinfection does not work.

Treatment

We disinfect, observing the products' contact times.

Rinsing

Surfaces that come into contact with food are rinsed.

Completion record

We prepare a document covering the work carried out.

Chill rooms are a separate case worth planning ahead. At low temperatures products act more slowly, and the rooms cannot stand open for long. In practice we usually do them when the room is being defrosted or emptied anyway, rather than as a separate visit in the middle of a production week.

What most often goes wrong on food premises: treatment is ordered for the kitchen or the production hall, but the waste area and the drains are left untreated — and that is where the permanent source is. The second typical mistake is treating surfaces that have not been cleaned: the result looks done, but is not. The third is ordering irregularly from different contractors, which leaves gaps in the log that an inspection spots immediately.

What we do not do

We do not develop HACCP systems, hygiene plans or internal procedures. We do not carry out audits and we do not issue compliance opinions. We do not process-clean or dismantle machinery. We do not clean the full ventilation system throughout the building — we treat the extraction filters and the accessible part of the duct. And we are not a substitute for daily cleaning: that stays your staff's work under your own regime.

And one more boundary we set out up front: we are a contractor, not a compliance consultant. If what you need is someone to tell you what should be written in your hygiene plan, that is a different service from a different specialist. What we can tell you is what is physically happening on the site and where the source of the problem is, and carry out the treatment.

Prices

Up to 100 m² — €1.20/m², 100–300 m² — €0.90/m², 300–1000 m² — €0.70/m². For regular scheduled treatment we prepare a separate quote with a volume discount.

Frequently asked questions

Do you develop HACCP systems?

No. We carry out the treatment and document it so that it can be filed within your existing hygiene documentation.

How often should treatment be carried out?

That depends on the type of site and on your hygiene plan. After an inspection we can suggest a frequency, but the final decision is the business's own responsibility.

Will treatment disrupt production?

We work outside production hours. We agree the treatment and airing times in advance so that the site is ready for the next shift.

Not sure which treatment you need?

Describe the situation — we will tell you whether treatment is needed at all, and which one.
