FOREWORD
The OIE Terrestrial Animal Health Code (Terrestrial Code) sets out standards for the improvement of terrestrial animal
health and welfare and veterinary public health worldwide, including through standards for safe international trade in
terrestrial animals (mammals, birds and bees) and their products. The health measures in the Terrestrial Code should
be used by the veterinary authorities of importing and exporting countries to provide for early detection, reporting and
control agents pathogenic to terrestrial animals and, in the case of zoonoses, for humans, and to prevent their transfer
via international trade in terrestrial animals and terrestrial animal products, while avoiding unjustified sanitary barriers to
trade.
The health measures in the Terrestrial Code have been formally adopted by the World Assembly of OIE Delegates,
which constitutes the organisation's highest decision-making body. The 22nd edition incorporates modifications to the
Terrestrial Code agreed at the 81th OIE General Session in May 2013. The 2013 edition includes revised information on
the following subjects: glossary; notification of diseases, infections, infestations and epidemiological information; criteria
for the inclusion of diseases, infections and infestations on the OIE list; procedures for self declaration and for official
recognition by the OIE; evaluation of Veterinary Services; veterinary legislation; collection and processing of bovine,
small ruminant and porcine semen; collection and processing of in vivo derived embryos from livestock and horses;
official health control of bee diseases; biosecurity procedures in poultry production; responsible and prudent use of
antimicrobial agents in veterinary medicine; zoonoses transmissible from non-human primates; introduction to the
recommendations for animal welfare; use of animals in research and education; animal welfare and beef cattle
production systems; infection with rabies virus; infection with rinderpest virus; infection with Trichinella spp.; infestation
of honey bees with Acarapis woodi; infection of honey bees with Paenibacillus larvae (American foulbrood); infection of
honey bees with Melissococcus plutonius (European foulbrood); infestation with Aethina tumida (small hive beetle);
infestation of honey bees with Tropilaelaps spp.; infestation of honey bees with Varroa spp. (varroosis); infection with
avian influenza viruses; Newcastle disease; infection with Mycoplasma mycoides subsp. mycoides SC (contagious
bovine pleuropneumonia); infection with equine arteritis virus; infection with Chlamydophila abortus (enzootic abortion
of ewes); infection with peste des petits ruminants virus; and infection with classical swine fever virus.
This edition includes three new chapters on infection with Echinococcus granulosus, on infection with Echinococcus
multilocularis, and on animal welfare and broiler chicken production systems.
The development of these standards and recommendations is the result of the ongoing work by the OIE Terrestrial
Animal Health Standards Commission (the Code Commission). This Commission, which comprises six elected
members, meets twice yearly to address its work programme. The Commission draws upon the expertise of
internationally renowned scientific experts to prepare draft texts for new texts in the Terrestrial Code and to revise
existing texts in the light of advances in veterinary science. The views of OIE National Delegates are systematically
sought through the twice yearly circulation of draft texts. The Code Commission collaborates closely with other Specialist
Commissions of the OIE, including the Aquatic Animal Health Standards Commission, the Biological Standards
Commission and the Scientific Commission for Animal Diseases, to ensure the recommendations contained in the
Terrestrial Code are based upon the latest scientific information.
The measures recommended in the Terrestrial Code are formally adopted by the World Assembly comprising the plenary
meeting of OIE National Delegates, who are in most cases the heads of OIE Member Countries' veterinary authorities.
The World Trade Organization (WTO) Agreement on the Application of Sanitary and Phytosanitary Measures (SPS
Agreement) formally recognises the role of the OIE to specify standards and recommendations as the international
references for animal health and zoonotic diseases. The SPS Agreement provides a multilateral framework,
incorporating WTO Members' rights and disciplines, to guide the development, adoption and enforcement of sanitary
measures to facilitate safe international trade. According to the SPS Agreement, WTO Members should provide a
scientific justification for their import health measures. It is preferable that these be based on OIE recommendations.
Where there are no OIE recommendations or in cases where a government chooses to apply more restrictive conditions
than those recommended by the OIE, the importing country should base its animal health measures on an import risk
analysis as described in the Terrestrial Code. The Terrestrial Code is thus a key part of the WTO legal framework for
international trade.
The Terrestrial Code is published annually in the three official OIE languages (English, French and Spanish). An
unofficial translation into Russian is also available from the OIE upon request. The Terrestrial Code may be viewed and
