Meysick and A.D. O'Brien. endstream As a possible biological weapons agent, SEB is stable, easily transformed into an aerosol, can produce multiorgan and system wide symptoms, and in extremely high doses, SEB induces shock and death. It is a common contributor to food poisoning in humans. If SEB were used as a biological weapon, it could be aerosolized and thus inhaled. Developing and fielding effective biological weapon sensors that can trigger an alarm would allow personnel to don masks before exposure, get into protective overgarments, and go inside, preferably into toxic-free collective protection shelters. x+ | Yonsei Med J. 24-07-2011 03:44:55 ZULU. biological weapon, also called germ weapon, any of a number of disease-producing agentssuch as bacteria, viruses, rickettsiae, fungi, toxins, or other biological agentsthat may be utilized as weapons against humans, animals, or plants.
