Claim summary · not a verbatim quotation
There are 1,500 BSL-3 laboratories in the United States.
The finding
What the evidence shows
The government's own oversight arm says this precise number can't really be known. A 2009 federal watchdog report found about 415 registered BSL-3 laboratories in the US as of 2004, a count that grew quickly in the years after, but it also concluded that federal officials don't know the true total because many BSL-3 labs are never required to register at all. So 1,500 is a plausible modern estimate, not a confirmed figure.
