What is the term for the use of biological agents for terrorist purposes?

The term for the use of biological agents for terrorist purposes is bioterrorism. This practice involves using harmful microorganisms or toxins, such as bacteria, viruses, or fungi, to intentionally cause illness or death in individuals, populations, or livestock, often for ideological or political objectives. Bioterrorism is a significant public health concern because it can lead to widespread fear, disruption of communities, and severe health risks.

Other terms, while related to biological agents, do not specifically refer to their use in terrorism. Biosecurity focuses on preventing the accidental release or misuse of biological agents and ensuring the safety of populations and environments from biological threats. Biodefense encompasses the strategies and actions aimed at protecting people from biological threats, including both natural outbreaks and bioterrorism. Biometrics, on the other hand, involves identifying individuals based on physical or behavioral characteristics and is not related to biological agents or terrorism. Thus, bioterrorism accurately captures the intended concept in the question.
