The World Organisation for Animal Health (OIE) international standards set out in the generic (‘horizontal’) chapters of the Terrestrial Animal Health Code
and Aquatic Animal Health Code
describe a continuum of measures aimed at preventing and controlling diseases and ensuring safe international trade. These standards serve as a basis for national Veterinary Services to develop appropriate national legislation that enables them to carry out their responsibilities effectively and well.
Countries’ Competent Authorities use the OIE standards as a framework to define and develop their core policies and programmes for animal health surveillance, disease notification, and disease prevention and control, as well as import risk analysis and trade measures.
The newly revised Animal Epidemic Prevention Law of the People’s Republic of China , which came into force on 1 May 2021, using the OIE standards as its reference, specifies the measures to be taken for the risk assessment of animal diseases, establishment of disease-free zones and compartments, development of animal disease elimination plans and reporting of animal diseases, and describes the responsibilities of official veterinarians.
In addition to this legislation, procedures and technical requirements for the risk analysis of import and export animals and animal products were also issued, to further standardise risk assessment of imported and exported animals and animal products .
The New Zealand Biosecurity Act of 1993  provides the legal framework to enable the detection, exclusion, eradication or effective management of pests and unwanted organisms. It covers:
- pre-border risk management and standard setting
- border management
- surveillance, readiness and response
- long-term pest management.
The Act requires that import health standards comply with Sanitary and Phytosanitary (SPS) Agreement principles and, by extension, OIE standards for trade in animals and animal products.
According to this Act, the Governor-General may, by Order in Council, declare any organism to be a notifiable organism for the purpose of surveillance and prevention. This places a duty on all New Zealanders to report the presence or suspected presence of notifiable organisms. The list of organisms in this Order is based on the OIE List of notifiable diseases.
The European Union (EU) Animal Health Law and its accompanying delegated and implementing Acts  became applicable on 21 April 2021. This new legal framework represents a comprehensive overhaul and modernisation of EU animal health legislation. The goals of the Animal Health Law include:
- simplifying and clarifying rules;
- categorising and prioritising animal diseases for EU intervention;
- better prevention, early detection and more effective control of animal diseases;
- safe and efficient trade, both within the EU single market and for the entry of goods from third countries.
Over all, the EU’s objective was to increase the convergence of EU animal health measures with the international standards of the OIE. Finally, the EU Animal Diseases Information System (ADIS) and OIE World Animal Health Information System (OIE-WAHIS) have also been interlinked.
