Using the NBC classification, which of the following is an example of a biological warfare agent?

• A. Mycotoxins
• B. Ricin
• C. Tularemia
• D. Plague

Answer: (C)

Understanding what counts as a biological warfare agent hinges on whether the threat is a living organism that causes disease. Tularemia fits this perfectly because it’s produced by a living bacterium, Francisella tularensis, and it can cause serious illness in people. Because it’s a real pathogen, it can be weaponized and disseminated as an infectious agent, which is the hallmark of a biological warfare threat within NBC classification. In contrast, mycotoxins and ricin are toxins—poisonous substances produced by organisms but not living agents themselves—so they’re categorized differently. Plague is caused by a living bacterium as well, but tularemia is the classic example often highlighted in this context for its virulence and ease of spread, which is why it’s chosen as the representative biological warfare agent here.
