Dear Claire

I refer to your OIA request dated 28 October concerning 1080 residues
found in mice

 

As requested, I attach the following Toxicology Analysis Reports:

T5682

T6024

T6025

Note that names have been redacted under section 9(2)(a) of the OIA to
protect privacy of individuals and also under section 9(2)(g)(ii) to
protect employees from improper pressure or harassment.  You have the
right to seek an investigation and review by the Ombudsman of this
decision.

 

In response to your questions, which are italicised below, we can provide
the following information:

What was the reason for testing the mice recovered from the Clinton BFOB
Southland 1080 operation with skin and tails removed as opposed to
including the skin and tails for testing the mice recovered from the
Caitlins?

For the Clinton operation the skin and tails were removed because they are
difficult to homogenise and residues found in the tail and skin are likely
to be minimal. For the samples from Catlins DOC specifically requested we
not remove the skin and tails, and we were able to homogenise them as
whole bodies.

 

Does 1080 bind to skin?  Does 1080 bind to muscle?  As confirmed from
Landcare previously, the accredited test method used in NZ does not
account for 1080 binding.  What test method does Landcare use to recover
1080 bound for research purposes?

No, 1080 does not bind to skin or muscle. Our current method extracts 1080
from various matrices and we run quality control samples to check method
recovery with each sample set.

 

When testing biological samples do you blend the sample first, mixing
different tissue types? 

No, we keep different tissue types separate.

 

Kind regards, Pam
