WOAH Terrestrial Animal Health Code

In scope terms the Terrestrial Code addresses the measures relevant to safe trade in terrestrial animals and their products. It covers, broadly, the quality and evaluation of veterinary services; disease notification and epidemiological information; import risk analysis; requirements relating to zoning, compartmentalisation, and surveillance; certification procedures and the role of veterinary certificates; animal welfare; and disease-specific chapters setting out recommendations for trade in relation to individual listed diseases.

The disease-specific chapters are the operative heart of it for traders, and they are structured around a question: given a disease and a commodity, what can an importing country reasonably require, and what should it accept? Some animal products carry negligible risk for a given disease regardless of the exporting country’s status; others carry risk that depends entirely on status, zone, surveillance, or processing. The code exists so that those distinctions are made on evidence rather than by reflex, and none of its recommendations are reproduced here.

For certain listed diseases, a member country may apply to WOAH for official recognition of its disease status — for the whole country or for a defined zone within it — and WOAH assesses the application against the code and publishes the outcome. This is a genuine anomaly in international standards. Codex recognises no country as anything, and the IPPC recognises no pest free area; recognition of a pest free area is something importing countries extend bilaterally. WOAH alone makes and publishes formal status determinations.

The commercial weight of this is difficult to overstate. Official status is what opens or closes markets for live animals and animal products, and a status loss following an outbreak can suspend a country’s exports of an entire product class within days. Recovery is not automatic: it requires meeting the code’s conditions for regaining status, which typically involve time, surveillance, and evidence. Whole national export sectors have been built and unbuilt around this mechanism.

The code develops two ideas that make trade possible when a disease is present somewhere in a country. Zoning defines a geographically delimited area with a distinct health status, so that an outbreak in one region need not close a whole country’s exports. Compartmentalisation defines a status boundary by management and biosecurity practice rather than geography — an establishment or set of establishments with a demonstrably separate epidemiological unit.

Both connect directly to the SPS Agreement’s regionalisation discipline, which requires members to adapt measures to the conditions of the area a good comes from. Zoning and compartmentalisation are the technical machinery that makes that legal obligation operable — without a defensible way to define and demonstrate an area’s status, adapting to it would be impossible. Whether an importing country recognises another’s zone or compartment is, in the end, a bilateral matter.

• Not plant health — the IPPC and its ISPMs govern that
• Not food safety generally — Codex and national food law govern that, though the codes meet on zoonoses
• Not aquatic animals — a separate WOAH code covers those
• Not quality or grade — grading standards and contracts govern that
• Not admissibility — importing countries set requirements and may exceed the code
• Not self-executing — the code regulates nothing until a country applies it

One boundary deserves particular care because it is genuinely blurred. Zoonoses are diseases transmissible between animals and humans, so they are simultaneously an animal-health matter for WOAH and a food-safety matter for Codex. The two bodies coordinate, but a reader should not assume that either one is the complete answer for a zoonotic hazard in a traded product; both layers, and the importing country’s law, apply.
