Nature: The US Department of Defense (DOD) announced on 27 May
that it had accidentally shipped live anthrax spores to labs in nine US
states and a US military base in South Korea. The
facilities that received the samples did not have systems in place to
protect lab employees against anthrax exposure because they were
expecting to receive spores that had been killed with radiation. It is
not clear how many people were actually exposed. The DOD says that 22
people in South Korea are getting preventive treatment, but it has not
confirmed how many people in the United States are being treated.
