biological threat
Living organism hazard
A biological threat is any organism, toxin, or pathogen—natural or engineered—that poses danger to humans, animals, or agriculture.
The term covers disease outbreaks, bioterrorism agents like anthrax or smallpox, and invasive species that could devastate ecosystems.
Intelligence agencies monitor biological threats from hostile nations.
The phrase often appears in security and public health contexts.
