Five Questions to Send Your Salmon Supplier

A free inquiry for university dining and procurement teams, plus a guide to reading the answers you get back

Most institutional buyers have never asked what veterinary drugs were used in the salmon they serve, and most suppliers have never been asked. These five questions are written so you can forward them as they are, under your own name. Reading the reply takes about ten minutes.

     

    What you’ll get:

    • A set of five questions, unbranded, ready to send to your supplier as a standard sourcing inquiry
    • A short guide to the common replies, such as what “ASC-certified,” “fully compliant,” and “antibiotic-free” each establish, and what they leave open

    Why Buyers Are Asking

    Open net pens hold tens or hundreds of thousands of fish in coastal water, where disease and parasites spread freely. Treating that disease takes drugs: Chile’s salmon industry, the largest supplier to the U.S., used 351 tons of antimicrobials in 2024, nearly all of it during ocean grow-out.¹ ²

     

    Verification is thin on this side. The U.S. tests roughly 0.1% of imported sea animal products for drug residues, and screens for three of the fourteen compounds the EU and Japan look for.³

     

    Certification audits a farm’s records and management systems. It does not test the fish you bought.

     

    An estimated 96% of antibiotics used in aquaculture belong to classes the WHO rates as important for human medicine.⁴

    Who We Are

    The Aquaculture Accountability Project researches industrial aquaculture and works with institutional buyers on sourcing decisions. We don’t sell anything.
