Recently, the General Office of the Ministry of Agriculture and Rural Affairs issued the "Guiding Opinions on Strengthening the Filing of Level 1 and Level 2 Animal Pathogenic Microbiology Laboratories", which aims to strengthen the biosafety management of animal pathogenic microbiology laboratories, improve the filing system, and standardize the content and procedures of laboratory filing.

People who don't know about biosafety laboratories may not know how many levels there are in biosafety laboratories and why they should be managed in different levels. Next, we will take a closer look at the hierarchy of biological laboratories.
According to the laboratory's level of biosafety protection against pathogenic microorganisms, and in accordance with the provisions of the national laboratory biosafety standards, the laboratory is divided into level 1 (biosafety level 1 (BSL-1), level 2 (BSL-2), *BSL-3), and level 4 (BSL-4).
Internationally, biological laboratories are divided into four levels: P1 (Protection Level 1), P2, P3 and P4 according to the biosafety level (BSL).

bsl-1
Also commonly referred to as P1, it is a basic laboratory.
Scope: Low harm to humans, animals and plants or the environment, no health**, animal and plant pathogenic factors. For example, common E. coli.
bsl-2
Also commonly known as P2, it is a basic laboratory.
Scope: It is suitable for children with moderate or potential hazards to humans, animals and plants or the environment, and will not cause serious harm to health, animals and the environment, with effective prevention and measures. For example, various types of hepatitis virus, mumps virus, etc.
bsl-3
It is also commonly known as P3 and is used for protective laboratories.
Scope: It is suitable for dealing with serious or even fatal diseases that are highly harmful to humans, animals and plants or the environment, or highly harmful to animals, plants and the environment. There are usually preventive and ** measures. For example, Bacillus anthracis, SARS coronavirus, etc.
bsl-4
Also commonly known as P4, it is the highest protection laboratory.
Scope: It is suitable for highly hazardous to humans, animals and plants or the environment, transmitted by aerosol routes or unknown transmission routes, or unknown, highly dangerous children. There are no preventive and ** measures. For example, Ebola virus, Marburg virus, etc.
In recent years, Hongcheng Innovation has actively deployed the biosafety and laboratory safety supervision market, and launched the "Laboratory Biosafety Digital Intelligence Supervision Platform" for the management of P2 and above biosafety laboratories to help laboratories improve the level of biosafety integration, collaboration and intelligent supervision.
