26th Australian Total Diet Study

​​​​​​​​​Last updated: July 2021

The 26th ATDS investigated levels of compounds classified as persistent organic pollutants (POPs) by the Stockholm Convention in a broad range of foods and beverages. The POPs investigated were:

  • ​Dioxins and dioxin-like compounds (DLCs) (hereafter referred to as 'dioxins')

​‐ ​​polychlorinated dibenzo-p-dioxins (PCDDs)

‐ ​polychlorinated dibenzofurans (PCDFs)

​‐ ​dioxin-like polychlorinated biphenyls (DL-PCBs)

  •  Non-dioxin-like polychlorinated biphenyls (NDL-PCBs).

A total of 33 different foods and beverages were sampled from all Australian states and territories over 2 sampling periods (April 2017 and February 2018).


The levels of dioxins and NDL-PCBs in the Australian food supply were generally lower than those reported internationally and in an earlier 2004 Australian study by FSANZ.

Dietary exposure to dio​xins and NDL-PCBs for the general Australian population is acceptably low and there are no food safety concerns for consumers.


The 26th ATDS confirms the safety of the Australian food supply in relation to levels of dioxins and NDL-PCBs.

We are of the view that current risk management measures, which include maximum levels in the Australia New Zealand Food Standards Code, where appropriate, are effective in ensuring that dioxin and NDL-PCB levels remain as low as reasonably achievable.​​
