This document aims to reduce the risks of pathogen infection in animal experiments, with a focus on biosafety control. Currently, my country's biosafety... Relevant national standards include GB 19489 "General Requirements for Laboratory Biosafety" and GB 50346 "Technical Specifications for Biosafety Laboratory Buildings". Standards such as GB/T 35823 "General Requirements for Laboratory Animal Experiments" mainly address laboratory management, laboratory building facilities, and laboratory animals. While general requirements are set, there are currently no technical guidelines for biosafety control throughout the entire process, from pre-experiment preparation and experimental operations to experimental waste disposal. There is an urgent need to develop national standards that guide the development of technical standards for biosafety control throughout the entire process of animal experiments involving pathogen infection. This document focuses on the biosafety control of animal experiments involving pathogen infection, comprehensively reviewing the biosafety aspects of experimental procedures. This document identifies key risk points and proposes preventative measures for these risks. It not only provides guidance for each operational step in animal experiments involving pathogen infection, but also addresses these risks. How to provide comprehensive technical guidance for preventing biosafety risks, prevent and control potential hazards, and provide support for subsequent actions after a hazard occurs? Provide scientific advice for effective handling. Biosafety Control Technical Specifications for Animal Experiments with Pathogen Infection

1 Scope

GB/T 47222-2026 is the Chinese national standard covering keeping an infection inside an animal facility - the containment level, the caging and ventilation, the personal protection, the handling of bedding, carcasses and waste, and the procedures for a spill or an escape. First edition, in force since 1 September 2026. It was issued on 27 February 2026 and has been in force since 1 September 2026, as a first edition. The document is under the responsibility of the Ministry of Agriculture and Rural Affairs. This page is published from the official record of the 2026 edition; the clause text of a standard this recent is not yet in circulation, and the figures, limits and tables it contains are those of the document itself, delivered in full with the English translation.

This document specifies the risk assessment, pre-experiment preparation, experiment implementation, emergency plans, records, and documentation procedures for animal experiments involving pathogen infection. General requirements for biosafety control in case management. This document applies to biosafety control in animal experiments involving pathogen infection in animal biosafety laboratories.
