Anomaly in 1080 testing of 6 Kiwi eggs

Claire Ogilwy made this Official Information request to Landcare Research New Zealand Limited

The request was partially successful.

From: Claire Ogilwy

Dear Landcare Research New Zealand Limited,

Can you please explain why when testing for 1080 in the 6 failed and dead kiwi eggs, the Method detection limit was raised from 2 parts per billion to 5 parts per billion.

The 6 failed kiwi eggs were laid in the 10 weeks after the 1080 operation in Rarewarewa, Northland May 1995.

Can you please provide copies of all MDL protocols with notes as to why they were changed and at which agency's request/instruction.

Has your testing facility ever tested for fluorinated amino acids and do you have the capabilities to do so.

Thanks,

Claire Ogilwy

Dear Claire
Your request concerning testing of 6 kiwi eggs for 1080, that you posted to on 25 December 2018, has just come to our attention on the FYI website.
We have checked our reporting and vertebrate pesticide residues databases and can find no references to testing of 1080 in kiwi eggs. However, both databases only go back to 2001 and we would need further contextual material, such as a report number, in order to search for information relating to periods earlier than this.
The method detection limit (MDL) used for testing the eggs will depend on when the data was generated, ie our methods are constantly evolving and this can affect the MDL. The MDL also depends on the amount of tissue provided for analysis.
Our Toxicology Laboratory has never tested for fluorinated amino acids and has no method to do so.
Yours sincerely
