They have also committed to testing the makeup of a number of other herbs and spices.

The ACCC investigation followed a complaint from consumer group Choice, which claimed seven of 12 individual dried oregano brand samples it bought last year and tested at a laboratory contained from less than 10 per cent to 50 per cent oregano.

The imports were instead padded with olive and sumac leaves.

“Suppliers of food products have an obligation to ensure ingredients of their products are accurately labelled and should be able to substantiate any representations made on the packaging that they approve,” ACCC chairman Rod Sims said.

To improve industry clarity, the ACCC has also agreed to administrative resolutions with the smaller suppliers of G Fresh Oregano Leaves Mediterranean, Master of Spices Oregano Leaves and Spice & Co. Oregano Leaves ensuring they cease supply of oregano products that contain contents other than oregano leaves and take steps to confirm the authenticity of future supply.

Investigations into other traders are continuing.
