Because of yet another mix-up with bioterror pathogens, a federal terrorism response training center in Alabama says it mistakenly exposed more than 9,600 firefighters, paramedics and other students to a deadly toxin over the past five years.
The Federal Emergency Management Agency’s Center for Domestic Preparedness blames an outside laboratory for a series of shipping errors since 2011 that resulted in the first-responder training center using in its classes a potentially lethal form of ricin powder. The poison, made from castor beans, is capable of killing at small doses.
