## Key points

- Farmed salmon had lower omega-3 levels than older data suggested.
- The study tested eight fillets from mid-Atlantic retailers.
- Zimmern urges improving aquaculture, not abandoning farmed seafood.

## Summary

A USDA-led study found that farmed Atlantic salmon fillets contained considerably less of two heart-healthy omega-3 fats than older federal data indicated. The findings matter because salmon is a popular source of these nutrients, but chef Andrew Zimmern says they should prompt efforts to improve fish farming rather than discourage people from eating farmed seafood.

Researchers reported 63.8% less EPA and 47.5% less DHA, potentially reflecting greater use of plant oils in fish feed. The study analysed eight fillets bought from retailers in the mid-Atlantic, so its representativeness across producers and regions is uncertain. The USDA said the fish remains nutritious and that the sample was selected using standard methods to assess changes in nutrient levels.
