West Coast mussel beds test clear

Date 14 August 2017

As part of a commitment to monitor any environmental changes following recent TBfree aerial possum control work on the West Coast, tissue samples were taken from shellfish at the 17 Mile mussel beds located at the southern end of the Barrytown Flats and tested for any sign of contamination by 1080 toxins.

The sample was tested by Landcare Research and results showed no traces of 1080.

Testing samples about 24 hours after the toxic application provides the greatest likelihood of detecting the presence of any residual 1080. After this timeframe, any 1080 present will be diluted or dispersed downstream so it is unlikely to be present for any uptake by mussel beds.

1080 bait is highly water soluble and only contains 0.15% of 1080 poison. It naturally breaks down in the environment into harmless substances through the process of biodegradation and dilution. It does not accumulate or leave permanent residues in soil, plants, water or animals.
