Whether your cleaning programme achieves what your hazard analysis assumes it achieves, assessed on chemistry, method, cleanability and evidence.
A cleaning and sanitation review assesses whether a cleaning programme is capable of achieving what the food safety system assumes it achieves. It covers the schedule, the chemicals and their concentrations, contact times, the method itself, and whether the procedure has been validated as effective. Cleaning is the prerequisite most hazard analyses lean on hardest, and the one least often supported by evidence.
The distinction that decides everything is between performing a clean and proving one. Cleaning happens on every site, records are signed and schedules are followed. Far fewer sites can produce evidence that the procedure removes what the hazard analysis assumes it removes.
Chemistry, method, cleanability and validation assessed together, ending in a plan for the evidence you are missing. Delivered on site, in any language, quoted on scope.
Time, action, concentration and temperature. Reducing one usually means increasing another, and most effectiveness is lost by cutting one without compensating.
| Variable | What it is | How it gets lost |
|---|---|---|
| Time | Contact time between chemical and surface. | Reducing contact time to shorten changeover, which cuts effectiveness disproportionately. |
| Action | Mechanical energy, whether scrubbing, turbulence in a clean in place circuit, or spray impact. | Foam applied and rinsed with no mechanical action at all. |
| Concentration | Chemical strength at the point of use, after dilution. | Dosing equipment uncalibrated, so actual concentration is unknown. |
| Temperature | Water and solution temperature, which drives the chemistry. | Cold water used because the hot supply does not reach that point. |
Eight elements, assessed against the operation as it runs and not against the procedure as written.
Every item of equipment, surface and area, with a frequency and a named owner.
The right chemistry for the soil, compatible with the surface and with any allergen requirement.
Dosing verified at the point of use, with calibration of dosing equipment.
Step by step, including dismantling, pre rinse, application, contact time and final rinse.
Whether the equipment can be cleaned by that method, including dead legs and hollow sections.
Proof the procedure achieves the required removal, generated under worst case conditions.
Routine checks confirming the validated procedure keeps working, with defined limits.
What is recorded, who checks it, and what happens when a check fails.
Eight failures, and the first is the one almost every site shares.
Cleaning happens, records are signed and nothing demonstrates the procedure removes what it needs to remove. The hazard analysis assumes control that has never been evidenced.
Under production pressure the chemical is rinsed early. Effectiveness falls disproportionately, and the record still shows the clean was completed.
Dosing equipment uncalibrated, or manual dilution by eye. The chemical may be at half strength or double, and neither is what was validated.
Foam applied and rinsed with nothing scrubbing, no turbulence in the circuit, or spray pressure too low. Chemistry alone rarely removes established soil.
Dead legs, hollow sections, porous surfaces and inaccessible joints. No procedure cleans what cannot be reached, and the answer is engineering, never a better chemical.
Evidence generated years ago, before a product change, a chemical change or an equipment modification. Validation attaches to the conditions it was performed under.
Visual inspection recorded as the verification for a procedure controlling a microbiological or allergen hazard. It confirms gross soil removal and nothing more.
Hygiene work done by a contractor or by a shift with no competence records. The most consequential prerequisite on site, carried out by the people least often trained on it.
The validation plan specifies the conditions each study should run under, since validation attaches to the conditions it was performed in.
| Element | What it covers |
|---|---|
| Schedule assessment | Coverage against equipment and areas, with gaps and orphaned items identified. |
| Chemical and method review | Chemistry against soil type and surface, with concentration and contact time assessed. |
| Cleanability findings | Equipment that cannot be cleaned by the specified method, with the reason stated. |
| Validation position | What evidence exists, whether it was worst case, and what it supports. |
| Validation plan | The studies needed to close the gap, with the conditions each should run under. |
| Verification regime | Routine checks matched to the hazard being controlled, with limits and escalation. |
| Record design | Cleaning records designed to be completed accurately under production conditions. |
| Competence gap | Where the people carrying out cleaning need training that they do not have. |
Manufacturers, processors, packers and catering operations. It suits sites whose hazard analysis dismisses hazards on the basis of cleaning, and any site where environmental monitoring keeps returning to the same location.
Your cleaning programme has never been validated.
Environmental monitoring keeps finding positives in the same place.
Changeover cleaning supports an allergen claim with no evidence behind it.
Contact times are cut under production pressure.
Dosing equipment has never been calibrated.
New equipment has been installed and cleaning was never reassessed.
Cleaning is carried out by a contractor outside your training system.
An auditor has questioned your validation or your verification.
You share the cleaning schedule, procedures, chemical data sheets, validation evidence and verification records.
Coverage is checked against every item of equipment, surface and area, with orphaned items identified.
Chemical selection is matched to soil and surface, and concentration, contact time, action and temperature are assessed as they run.
Equipment is examined for whether it can be cleaned by the specified method, including dead legs and hollow sections.
Existing evidence is assessed for whether it was worst case and for what it supports.
A validation plan is produced with the conditions for each study, alongside verification, record design and competence findings.
Carrying out validation studies or laboratory analysis. The review specifies what study is needed and under what conditions, and your laboratory performs it.
Chemical supply and no supplier recommendations. No commission or referral arrangement exists with any chemical company, so the assessment stays on whether the chemistry fits.
Physical remediation. Where equipment cannot be cleaned, the answer is engineering and the decision is yours.
Every review is quoted against its own scope. A single line with open plant cleaning and a multi line site with clean in place circuits are very different pieces of work. These factors set the price.
These are the primary sources this work is built on. Where a market you sell into has its own requirement, that takes precedence and we assess against it.
Cleaning removes soil and food residue from a surface. Sanitation reduces microorganisms on that cleaned surface to an acceptable level. Sanitation applied to a dirty surface achieves very little, because residue shields organisms from the sanitiser and consumes it.
Time, action, concentration and temperature. These four variables determine whether a cleaning procedure works. Reducing one usually means increasing another, and cutting contact time to shorten changeover without compensating elsewhere is one of the most common way effectiveness is lost.
By generating evidence that the procedure achieves the required removal under worst case conditions, meaning the hardest soil, the least accessible points and the shortest permitted contact time. The method depends on the hazard, whether microbiological, allergen or chemical residue. Validation attaches to the conditions it was performed under.
Whenever something changes that could affect the outcome. A new product or soil type, a chemical change, modified or new equipment, a change to the procedure, or a persistent verification failure. Standards also expect periodic review even without change.
For gross soil removal, it has a place. For a procedure controlling a microbiological or allergen hazard, it proves nothing at the levels that matter. Verification has to match the hazard the procedure is controlling.
Then the answer is engineering, not a stronger chemical. Dead legs, hollow sections, porous surfaces and inaccessible joints defeat any procedure. The options are modification, dedication to a single product, or replacement, and the review states which applies.
It is a community of microorganisms attached to a surface and protected by a matrix they produce. Biofilms resist routine cleaning and sanitation substantially, and they establish where cleaning has been marginal over time. Persistent positives in one location frequently indicate one.
Either works. What matters is that whoever does it is trained, competent and inside your system, with records to evidence it. Contract hygiene teams frequently sit outside the training system, which is a serious gap given how much the food safety system rests on their work.
By verifying it at the point of use and calibrating the dosing equipment. Manual dilution by eye and uncalibrated dosing both produce concentrations that were never validated, in either direction.
Not reliably, and it can cause harm. Overdosing wastes chemical, increases rinse burden, risks residue on food contact surfaces and can damage equipment. The validated concentration is the correct one.
A prerequisite review covers all the programmes underneath your HACCP plan at a survey level. This one goes into cleaning in depth, including chemistry, method, cleanability and validation evidence. Sites where cleaning is the specific concern should take this one.
A schedule assessment, a chemical and method review, cleanability findings, a validation position stating what your evidence supports, a validation plan for the gaps, a verification regime matched to the hazard, improved record design and a competence gap assessment.
Confi Food assigns work by subject. HACCP, labelling, certification standards, regulatory compliance, supplier assurance and monitoring are separate disciplines, and each piece goes to someone who works in that area. Every deliverable is reviewed internally by a second specialist before it reaches you.
Our technical positions are built from primary sources, meaning the legislation, the competent authority, Codex Alimentarius, the certification scheme owner or the relevant standards body. We set out how that works in our technical review and editorial policy, and what happens at each stage of an engagement in how Confi Food works.
