Biosecurity refers to the measures and practices designed to protect human, animal, and plant health from harmful biological agents. This includes preventing the introduction and spread of diseases, pests, and invasive species that can threaten ecosystems and agriculture. Effective biosecurity involves monitoring, controlling access to sensitive areas, and implementing sanitation protocols. In agriculture, biosecurity is crucial for safeguarding crops and livestock. Farmers often use strategies such as quarantine, vaccination, and pest management to minimize risks. Governments and organizations also play a role by establishing regulations and guidelines to enhance biosecurity at local, national, and international levels.
