I'm not sure what other information you are looking for. The biosafety 
level is determined by the US Public Health Service. Here is a 
definition of the biosafety levels posted on the www.atcc.org web page:
Biosafety Levels
ATCC products are sent with the condition that you are responsible for 
their safe storage, handling, and use. ATCC is not liable for damages 
or injuries resulting from receipt and/or use of ATCC materials.
ATCC has classified cultures and related products by biosafety level 
(BSL) for purposes of packaging for safe shipment. The classification 
is based on assessment of the potential risk using U.S. Public Health 
Service guidelines, background information on the material provided by 
the depositor and review of the material by ATCC scientists familiar 
with the material. Each item is evaluated individually and in some 
cases the ATCC assigned biosafety level is more restrictive. Those 
items in BSL-1 are not known to cause disease in healthy adult humans. 
Materials in BSL-2 present a moderate risk and should be handled under 
BSL-2 guidelines. Handling of BSL-3 strains requires the use of BSL-3 
laboratory practices and containment. All infectious materials should 
be handled under the supervision of a competent and knowledgeable 
scientist. It is ultimately the recipient's and their institution's 
responsibility to determine the biosafety level and work with the 
material under the appropriate containment for the laboratory 
manipulations being performed.
The Web site for the CDC's Office of Health and Safety has complete 
descriptions of the biosafety levels in the text of the publication 
Biosafety in Microbiological and Biomedical Laboratories, (BMBL) 5th 
Edition (HHS Publication No. (CDC) 93-8395. U.S. Department of Health 
and Human Services, Centers for Disease Control and Prevention and 
National Institutes of Health; U.S. Government Printing Office: 
Washington DC; 2007). It is available in its entirety online. 
Information on agent risk assessment may be found in the Agent Summary 
Statements of this publication.
