Six months ago our daughter developed severe behavioural problems, including depression, lack of motivation, poor sleeping habits, lethargy and loss of enthusiasm. These were very uncharacteristic of a hard-working fulltime student and a complete puzzle to her concerned teachers. As a consequence, her exam results declined, as did her study performance.

Her problems were eventually traced to her consumption of home-baked products containing Dairysoft, a butter-oil blend manufactured by one of Australia's largest companies, the Murray Goulburn Co-Operative Ltd.

Our daughter is known to be affected by antioxidants 310-312 and 319-321 and several other food additives. Before she started using Dairysoft, verbal advice was obtained from Murray Goulburn that there were no antioxidants in the oil which comprised 22% of the product.

After months of increasing problems, we contacted Murray Goulburn again and were now that informed that the canola oil in the product did in fact contain 320, Butylated Hydroxyanisole.

Our daughter removed Dairysoft from her diet and she has since made a complete recovery, although there can be no compensation for the six months of pain and uncertainty which she suffered. Following complaints, Murray Goulburn have now correctly labeled this product, although without any food recall, product safety or public apology notice. – parents from Darwin.
