WASHINGTON – The Pentagon says the number of laboratories that received shipments of live anthrax samples has grown to 68, including one in the United Kingdom.
Defense officials disclosed in late May that low concentration samples of live anthrax were shipped to labs from the Army's Dugway Proving Ground in Utah, beginning in 2005 or 2006.
.Army Col. Steve Warren says the new tally includes labs in 19 states and the District of Colombia and four countries, and involves samples from five batches, up from the four previously reported.
The anthrax was supposed to have been killed with gamma rays before being shipped for use by commercial labs and government facilities in research. But for reasons not yet explained, the anthrax apparently remained alive.
Officials say there is no public health risk.
