Biosafety level 4 (BSL-4) organisms are dangerous or exotic agents which pose high risk of life-threatening disease, aerosol-transmitted lab infections, or related agents with unknown risk of transmission.[citation needed]
US federal biocontainment regulations
Biosafety level 4 laboratories are designed for diagnostic work and research on easily respiratory-acquired viruses which can often cause severe and/or fatal disease. What follows is a list of select agents that have specific biocontainment requirements according to US federal law. Organisms include those harmful to human health, or to animal health.[1] The Plant Protection and Quarantine programs (PPQ) of the Animal and Plant Health Inspection Service (APHIS) are listed in 7 CFR Part 331. The Department of Health and Human Services (HHS) lists are located at 42 CFR Part 73.3[2] and 42 CFR Part 73.4.[3] The USDA animal safety list is located at 9 CFR Subchapter B.[4]
Not all select agents require BSL-4 handling, namely select bacteria and toxins, but most select agent viruses do (with the notable exception of SARS-CoV-1 which can be handled in BSL3). Many non-select agent viruses are often handled in BSL-4 according to facility SOPs or when dealing with new viruses closely related to viruses that require BSL-4. For instance, Andes orthohantavirus and MERS-CoV are both non-select agents that are often handled in BSL-4 because they cause severe and fatal disease in humans. Newly characterized viruses closely related to select agents and/or BSL-4 viruses (for example newly discovered henipaviruses or ebolaviruses) are typically handled in BSL-4 even if they aren't yet known to be readily transmissible or cause severe disease.[citation needed]
International BSL-4 regulations
Globally, there are no official agreements on what agents must be handled in BSL-4. However, select agents and toxins originating or ending in US BSL-4 labs must adhere to US select agent laws.[citation needed]
