Biosecurity and quarantine officers play a crucial frontline role by inspecting animals, monitoring imports and exports, enforcing quarantine regulations, and ensuring compliance with international animal health standards. They work at airports, seaports, border checkpoints, and quarantine stations. Their duties include risk assessment, sample collection, documentation review, and coordinating responses to detected threats. Growing global trade, transboundary diseases, and One Health awareness have heightened the importance of strong biosecurity systems. The role requires vigilance, regulatory knowledge, and strong communication skills.
