The strawberry yoghurt run finishes at 11:40. Plain yoghurt is scheduled for 12:00. The supervisor wants the filler moving again, the operators have already rinsed the hopper, and a roll of strawberry lids is still sitting on the capper "for tomorrow."

Twenty minutes is plenty of time to change products. It is not always enough time to *finish* the previous one.

That gap is what line clearance is for. Between two products or SKUs on the same line, someone has to confirm that nothing from the last run (residue, work in progress, labels, lids, settings or paperwork) can end up in the next one. When that check is skipped, the result is rarely dramatic on the day. It shows up later as a mislabelled carton, a pack with the wrong date code, an allergen in a "plain" product, or a batch record nobody can reconcile.

This article is for production supervisors, QA leads and owners of small and mid-sized food and agro factories in Kenya: dairies, millers, snack makers, juice processors, bakeries and spice packers. It gives you an eight-point line clearance checklist to run at every changeover. It is operations guidance, not legal advice.

## Why changeovers need their own checklist

Most factories already have cleaning schedules and some form of start-up check. Line clearance sits between them: it is the decision that **the previous product is fully gone and the line is ready for the next one**.

Kenyan and regional guidance points in the same direction, even if it does not use the phrase "line clearance":

- The Ministry of Health [Checklist for Food Hygiene Licensing (April 2023)](https://health.go.ke/sites/default/files/2023-05/Checklist%20for%20Food%20Hygiene%20Licensing%20April%202023.pdf) (see also the [MoH checklist page](https://www.health.go.ke/food-hygiene-licensing-checklist)) expects food-contact surfaces that can withstand repeated cleaning and sanitising, a hazard monitoring system that covers processing, SOPs for hygiene, cleaning and disinfection, and a HACCP plan.
- [EAS 39:2001, *Hygiene in the food and drink manufacturing industry: Code of practice*](https://law.resource.org/pub/eac/ibr/eas.39.2001.pdf), sets out documented cleaning programmes for food-contact surfaces, with records showing the programme was followed, and physical zoning to prevent cross-contamination.
- The KEBS [Standardization Mark](https://qualityassurance.kebs.go.ke/standardization-mark/) process includes factory inspection of process controls; the published [initial inspection report form (STA-10)](https://kebs.org/wp-content/uploads/2024/02/STA-10-Initial-inspection-report.pdf) shows the kind of records inspectors look for.
- On the equipment side, Tetra Pak Kenya describes [cleaning in place (CIP)](https://www.tetrapak.com/en-ke/insights/cases-articles/cleaning-in-place-to-secure-food-safety) as preparing equipment for processing either after a normal run *or when switching a line from one recipe to another*.

None of this replaces your HACCP plan or your own advisers. It does support a simple rule: **a changeover is finished when someone has checked it and signed it, not when the line is wet.**

## The 8-point line clearance checklist

Run these checks at every product or SKU change on a line. Some changeovers are light (same product, different pack size); some are heavy (allergen to non-allergen, flavoured to plain). Your SOP should say which checks apply to which type. The list below is the full version.

### 1. Is the previous product and batch closed out?

Before anything is cleaned, finish the last run:

- Record the final quantity produced and the batch or lot number for the run that just ended.
- Remove all work in progress (WIP), part-filled containers, rework and samples from the line, or move them to a clearly marked, segregated area.
- Return unused raw materials and packaging to the store under their lot identity, or label them clearly for the next scheduled run of that product.

If last run's WIP is still on the line when the next product starts, you have a mixing risk, not a changeover.

### 2. Has food-contact equipment been cleaned and sanitised per SOP for this changeover type?

Clean to the procedure, not to habit:

- Use the cleaning or CIP programme your SOP defines for *this* changeover (for example a rinse between two pack sizes of the same product, a full clean between different recipes).
- Include the parts that collect residue: hoppers, fillers, nozzles, mixers, sieves, conveyors, scrapers and hand tools.
- Record who cleaned, which programme was used and when it finished.

A rinse that is fine between two batches of the same product may not be enough when the recipe changes.

### 3. Does a visual check (and any required verification) confirm no previous product residue?

Someone other than the person who cleaned should look:

- Check food-contact surfaces, corners, seals and dead spots for visible residue of the previous product.
- Run any verification your plan requires for this changeover type (for example a rinse-water check or a swab test).
- If residue is found, re-clean and re-check. Do not "start slow and let the first packs flush it out."

### 4. Are only the new product's packaging, labels and coding on the line?

Labels and lids cause more changeover mistakes than residue:

- Remove every leftover label, lid, sleeve, carton and pouch from the previous product, including partial rolls and spares under the machine.
- Bring only the new product's packaging to the line, matched against the production order.
- Change the date and batch coder to the new product's code and check one printed sample before running.

A plain yoghurt in a strawberry cup is a labelling error, and in some cases an allergen error too.

### 5. If the allergen profile changes, have allergens, dedicated tools and colour-coding been handled?

Switching from a product that contains an allergen to one that does not (for example a peanut snack to a plain maize snack, or a milk-containing blend to a dairy-free one) needs extra steps:

- Follow the stricter cleaning programme your plan sets for allergen changeovers.
- Swap or remove dedicated tools, scoops and containers; use colour-coding where you have it.
- Remove any allergen-containing ingredients from the line area, not just from the hopper.
- Schedule allergen-free products before allergen products where possible, so fewer changeovers carry this risk.

### 6. Are the correct recipe/BOM version and process settings loaded for the new product?

The line can be spotless and still make the wrong thing:

- Confirm the production order references the right product, recipe or bill of materials (BOM) and the current version.
- Check machine settings for the new product: fill weight or volume, temperatures, times, speeds, sieve size or grind setting, seasoning dose.
- Confirm the raw material lots staged for the new run are the ones issued for it.

For spice packers moving from blend A to blend B, or millers changing grades, this is where many "right line, wrong product" errors start.

### 7. Are the line documents updated with who cleared it, when, and from which product to which?

If it is not written down, it did not happen. Record:

- Product and batch *from* and product and batch *to*.
- Time the previous run ended, cleaning completed, and clearance was given.
- The name of the person who cleared the line and the person with authority to release it for the next run (often a QA lead or shift supervisor, not the operator who wants to restart).

This record is what you will rely on during a [mock recall](https://factoraerp.com/en/blog/how-to-run-a-mock-recall-food-traceability-kenya) or customer complaint.

### 8. Has first-off / start-up QC passed before the line runs at full speed?

The clearance is confirmed by the first good packs, not by the signature alone:

- Run a short start-up and check the first-off packs: weight or volume, seal, label, date and batch code, appearance and any quick tests your plan lists.
- Hold the start-up packs until they pass. If they fail, stop, correct and recheck.
- Only then run at full speed, and treat the start-up packs according to your plan (release, rework or discard).

Finished goods should still pass your normal release step, such as a [QA hold before the batch leaves the warehouse](https://factoraerp.com/en/blog/qa-hold-checklist-before-batch-leaves-warehouse-kenya).

## Habits that make line clearance stick

- **Plan changeovers in the schedule.** If the schedule shows 12:00 start with no clearance time, the checklist will lose. Put realistic clearance time between products.
- **Sequence to reduce risk.** Run light to dark, plain to flavoured, allergen-free to allergen where your process allows. Fewer heavy changeovers means fewer chances to miss something.
- **Separate the cleaner from the checker.** The person who cleans should not be the only person who confirms the line is clear.
- **Keep packaging tight.** Issue labels and lids to the line per production order and return the remainder at clearance. Loose rolls cause mix-ups.
- **Look after the equipment.** Worn seals, cracked scrapers and leaking valves hold residue and make cleaning harder. Link changeover findings to your [preventive maintenance plan](https://factoraerp.com/en/blog/preventive-maintenance-basics-food-agro-factories-kenya).

**Illustration (not real customer data):** imagine a snack factory that runs a peanut-coated product in the morning and a plain salted product after lunch. The operators clean the fryer and seasoning drum, but a half-used tub of peanut coating stays beside the seasoning station, and a roll of the morning's labels is still on the spare spindle. An operator tops up the drum from the nearest tub and the labeller switches to the spare roll when the first one runs out. A clearance check that asked "are only the new product's ingredients and labels at the line?" would have caught both before the first pack was sealed.

## Where an ERP helps

A printed checklist and a signed line log are a good start, and many factories should begin there. The difficulty grows with more lines, more SKUs and more shifts.

FactoraERP links production orders to recipes, BOM versions, issued material lots and batch records. A changeover can be recorded against the line, with the previous order closed before the next one starts, so the batch record shows which lots went into which run and who released the line. That supports [FEFO stock control](https://factoraerp.com/en/blog/reduce-expiry-spoilage-losses-fefo-batch-expiry-tracking), QA holds and traceability later.

## FAQ

**What is line clearance in a food factory?**  
It is a documented check at a product or SKU change that confirms the previous product, its WIP, residue, packaging, labels and settings have been removed from the line, and that the line is set up correctly for the next product before production starts.

**Is line clearance the same as cleaning?**  
No. Cleaning is one part of it. Line clearance also covers closing out the previous batch, removing old packaging and labels, loading the right recipe and settings, recording who cleared the line, and passing start-up checks.

**Who should sign off line clearance?**  
Usually a named QA lead or shift supervisor, with authority to release the line. The person who cleaned the equipment should not be the only person who checks it.

**Do I need a full clean at every changeover?**  
Not always. Many factories define changeover types, for example a light changeover between pack sizes of the same product and a full clean between different recipes or allergen profiles. Your SOP and HACCP plan should define which cleaning applies to each type.

**How long should a line clearance take?**  
It depends on the line and the changeover type. The practical rule is to measure it, put that time into the production schedule, and stop treating clearance as something to squeeze in between runs.
