Biodefense refers to short term, local, usually
military measures to restore
biosecurity to a given group of persons in a given area who are, or may be, subject to
biological warfare— in the
civilian terminology, it is a very robust
biohazard response. It is technically possible to apply biodefense measures to protect
animals or
plants, but this is generally uneconomic. However, protection of water supplies and food supplies are often a critical part of biodefense. Various definitions of
biosafety emerged in different professions to guarantee non-human health.
