Book excerpt: This report presents the results of a Technical Working Group (TWG) meeting, where experts from competent authorities, intergovernmental organizations, the aquaculture industry, academe, and research institutions examined the two previous consultations on the Progressive Management Pathway for Improving Aquaculture Biosecurity (PMP/AB) and clarified issues and concerns raised during these two consultations. A consensus was reached on the definition of the PMP/AB as a pathway that builds on existing frameworks, supported by appropriate tools (via the “PMP/AB toolkit”). The PMP/AB focuses on aquaculture biosecurity, which includes health management and reduction of antimicrobial resistance (AMR). The PMP/AB will not directly focus on food safety; however, it will promote sustainable aquaculture production with good husbandry practices, environmental practices, and prudent treatment or antimicrobial use.
