Regulation R638 of 2018 and Pest Control: What Every Food Premises Must Have

If your Certificate of Acceptability is up for renewal, or an Environmental Health Practitioner has just walked your production floor with a clipboard, the regulation behind their questions is Regulation R638 of 2018, arguably the single most important piece of food hygiene law in South Africa, with pest control at its centre. Most quality managers can quote SANS 10049 or Act 36 of 1947 chapter and verse while treating R638 as background noise, a mistake, since R638 is the legal floor everything else stands on, and the document an inspector opens when deciding whether a premises may keep trading.

This article sets out what R638 requires on pest control and structural pest-proofing, how it links to your Certificate of Acceptability, and where it sits relative to SANS 10049 and Act 36 of 1947 in the compliance stack.

What Regulation R638 actually is

Regulation R638 is the common short name for the Regulations Governing General Hygiene Requirements for Food Premises, the Transport of Food and Related Matters, published as Government Notice R638 on 22 June 2018, under the Foodstuffs, Cosmetics and Disinfectants Act 54 of 1972. It replaced the earlier R962 of 2012, tightening the hygiene, structural and food-handling duties that apply to every premises where food is manufactured, prepared, packed, stored, transported or sold.

R638 is not a management system standard like HACCP or a certification scheme like FSSC 22000 or BRCGS. It is national law, enforced by local authority Environmental Health Practitioners. Where a private certification audit is a commercial requirement imposed by a customer, R638 is a legal requirement imposed by the state, and non-compliance carries statutory consequences, not just a lost contract.

The Certificate of Acceptability and pest control

The mechanism that gives R638 its teeth is the Certificate of Acceptability (CoA). Under the regulation, no person may conduct business as a food premises, and no food may be handled on any premises, unless it holds a valid CoA issued by the local authority. The certificate is premises-specific, issued after an EHP inspection, and can be withdrawn if conditions no longer meet the regulation's requirements.

Pest control is one of the standard grounds an EHP uses to refuse, suspend or withdraw a CoA. Evidence of an active infestation, droppings, gnaw marks, or structural conditions that invite pest entry are findings an inspector is trained to look for. A facility that cannot show it is free of pests, and cannot show a credible ongoing programme to keep it that way, risks losing its licence to trade, not merely an audit finding.

Structural and design duties: keeping pests out by design

R638 places the primary duty for pest exclusion on the building itself, not on reactive baiting. The regulation requires food premises to be designed, constructed, equipped and maintained in a manner that prevents the entry, harbourage and breeding of pests, and that allows surfaces to be effectively cleaned and sanitised. In practical terms, an EHP or auditor walking a site against this duty is checking for:

• Sealed building envelope, no gaps under doors or unsealed penetrations that let in Rattus norvegicus (Norway rat) Rattus rattus (roof rat) or Mus musculus (house mouse).
• Screening of windows, vents and drains, insect-proof mesh and pest-proof drain covers that still allow drainage.
• Self-closing, well-sealed doors between production, outside, loading docks and waste areas.
• Cleanable walls, floors and ceilings, intact finishes without cracks or voids that harbour Periplaneta americana (American cockroach) or Blattella germanica (German cockroach).
• Effective drainage that does not pool water, a breeding condition for Musca domestica (house fly).
• Correct waste handling, covered, pest-proof receptacles and a collection frequency that prevents accumulation.

These are structural duties a pest control contract alone cannot solve. A technician can bait a gap under a loading bay door every month for years; sealing the gap removes the entry point permanently. R638 treats prevention through design as the primary obligation, with monitoring and treatment as the ongoing layer that catches what design alone cannot.

The prohibition on pests, insects and rodents

R638 is also explicit that food premises must be free of pests, a standalone duty, separate from the structural requirements above, since good design is not enough if pest activity is nonetheless present. The regulation prohibits insects, rodents and other pests in food handling and storage areas, and requires that where evidence of pests is found, effective steps are taken to eliminate them and prevent recurrence. A single visible cockroach, a rodent dropping near raw material intake, or an unexplained fly population in a packing area is not just housekeeping under R638, it is evidence the premises may not meet the hygiene standard the regulation sets, with direct implications for the Certificate of Acceptability. This is where an ongoing, documented Integrated Pest Management programme becomes the practical expression of a legal duty rather than good intentions. For a shop or supermarket floor, our retail and supermarket pest control programmes make that duty a documented, managed reality.

Chemicals, application standards and the regulatory stack

R638 does not prescribe which pesticide products may be used or how they must be applied, that detail sits in other legislation R638 assumes will be followed. Any pesticide used on a food premises must be registered under the Fertilizers, Farm Feeds, Agricultural Remedies and Stock Remedies Act 36 of 1947, applied by a PCO registered with the Department of Agriculture, in line with SANS 10133. Read together, the instruments form a stack, not a duplication:

Certification schemes such as FSSC 22000 and BRCGS reference R638 and SANS 10049 as the baseline their own, more prescriptive clauses assume is already in place.

EHP and inspector powers: notices and closure

R638 gives Environmental Health Practitioners real enforcement powers, not an advisory role. An EHP may enter and inspect a food premises, examine records, take samples, and where conditions present a health risk, issue a formal notice requiring improvements within a set period. Where the risk is serious or immediate, an active, uncontrolled infestation in a production area is a clear example, the regulation supports closure of the premises or a prohibition on sale of affected food until the risk is remedied.

This is materially different to a supplier audit non-conformance: a closure notice under R638 stops production and revenue immediately, while a private audit finding typically allows a corrective action period. Producing a current pest risk assessment, station map and service history the moment an EHP asks, the way the myASConline one-click audit pack is built to do, demonstrates an active, managed programme rather than an ad hoc response.

Building practical R638 compliance into your pest programme

Translating R638 into a working programme means pairing a structural pest-proofing survey, building envelope, drainage, waste areas, cleanability, defects logged and closed out, with an ongoing IPM programme: risk-based station placement, registered-PCO servicing, trend monitoring and an Act 36-registered chemical register applied per SANS 10133. Both halves need to be visible in one place when an EHP or auditor asks, the gap a well-prepared audit file is built to close. ASC Pest Control designs commercial IPM programmes around this dual reading of R638 for clients across Gauteng and the Eastern Cape. On a factory or distribution site, our commercial pest control programmes pair the proofing survey with ongoing monitoring.
