Agreed Outline and Content

Introduction:

This document presents the final outline and content for the 2009 New Zealand Total Diet Study (NZTDS) being undertaken by the New Zealand Food Safety Authority (NZFSA). This content was agreed following consideration of the comments received from interested parties on the proposed outline for the 2009 NZTDS published 30 June 2008.

The 2009 NZTDS is the second to be undertaken by NZFSA and will follow a similar design to the 2003/04 NZTDS. It will again focus on the assessment of dietary exposure to chemical residues, contaminant elements and selected nutrients, from representative foods, across the average diet of different age-sex groups within the New Zealand population. Foods will be prepared as for consumption (i.e. banana, peeled; meat, cooked) prior to analysis.

The 2009 NZTDS will sample 123 foods over four sampling rounds during the calendar year 2009. The foods will be analysed for about 260 agricultural compounds; the contaminant elements arsenic, cadmium, lead, and mercury (total and methyl); and the nutrient elements iodine, selenium and sodium. Results for each sampling round will be made available as soon as practical after the analysis for each round is completed. Dietary exposure assessments for a range of age-sex population groups will be estimated.
