Agricultural Compounds to be tested for in 2003/04 New Zealand Total Diet Survey

Pesticide multi-residue screen
Acid herbicide multi-residue screen
Dithiocarbamate screen (analysed as CS2)
Who's doing the testing?

The 2003/04 New Zealand Total Diet Survey (NZTDS) will analyse the foods contained in the 2003/04 NZTDS Food List for a range of agricultural compounds. Testing will be undertaken for pesticides, dithiocarbamate and acid herbicide compounds by way of three separate screens. The screens for pesticides and acid herbicides are multi-residue screens, in that each compound in the screen can be separately quantified. The dithiocarbamate (DTC) screen analyses for CS2, a breakdown product of DTCs, and does not differentiate which individual DTC in the screen produced the result.

Screens are a ’package deal' in that each screen contains a specific set of compounds. While the exact make-up of screens does change over time the addition or deletion of any particular compound from a specific screen and the related validation of methods and calibration of equipment etc means that short term or one-off changes are not practicable.

The pesticides, dithiocarbamate and acid herbicide compounds that are to be screened in the 2003/04 NZTDS are listed below.

Who's doing the testing?

ESR is subcontracting the provision of the multi-residue agricultural compound testing to be undertaken in the 2003/04 NZTDS. The analytical providers selected were chosen based on the following criteria:-

their reputation in the field;
their experience with the analytes in question in the wide range of food matrices involved in the NZTDS;
the status of accreditation of the laboratory and methods;
an inspection of their laboratory facilities;
previous contracts of a similar size and complexity;
their ability to deliver timely and robust results;
the accuracy of methods as demonstrated by results from international collaborative proficiency programmes for these types of compounds in varied food matrices;
the quality assurance/quality control system they have in place;
their equipment and back-up equipment;
the breadth and significance of the compounds in their pesticide screen;
the limits of detection of the pesticides involved;
price.
