Biosecurity refers to measures taken to prevent, control, or manage risks associated with biological threats to human, animal, or plant health, as well as to the environment. This includes efforts to prevent the introduction or spread of harmful organisms such as pathogens, pests, or invasive species, through various strategies such as quarantine, hygiene practices, surveillance, and risk assessment. Biosecurity is important for protecting public health, food security, and biodiversity, and is relevant to fields such as infectious disease control, agriculture, wildlife management, and biodefense.
