The Washington Dept. of Ecology completed the final environmental assessment of a proposal to use the pesticide imidacloprid to control burrowing shrimp.

The supplemental environmental review found:

 

  • Significant impacts to sediment quality and benthic invertebrates.
  • Adverse impacts to juvenile worms and crustaceans in the areas treated with imidacloprid and the nearby areas covered by incoming tides.
  • Concern about non-lethal impacts to invertebrates in the water column and sediment.
  • New information shows a risk of impacts from imidacloprid even at low concentrations.
  • Likely indirect impacts to fish and birds if food sources are disrupted.
  • Little known direct risk to fish, birds, marine mammals, and human health.
  • Increased uncertainty about long-term, non-lethal, and cumulative impacts.
  • Continued knowledge gaps about imidacloprid.

This matters to everyone, not just Washingtonians. Nearly a quarter of the oysters grown in the US are grown in Willapa Bay and Grays Harbor.

These oysters are shipped all over, including to growers on Tomales Bay.
