The Turmeric Had Paint Pigment in It

Of everything in the Four Corners food fraud investigation, the turmeric finding is the one I'd struggle to invent. The program had 28 turmeric products from 11 brands tested, and reported that three failed. According to the testing, one contained lead chromate, a pigment used in paint, along with iron oxide, apparently there for colour and weight; another was bulked out with an undeclared starchy filler; and a third, marketed as pure, contained plant material that wasn't turmeric at all. The companies involved dispute the findings, and the lab's methods have been publicly questioned since, the same caveats that hang over the rest of this series.

The pattern is the thing. It's always the powders. Once a plant is dried and ground, your eyes are useless, and so is everyone else's along the chain. A jar of yellow dust could be rhizome, filler or pigment, and only a lab knows the difference. That's what makes ground spice such a comfortable place for fraud to live.

The honest limit of my pitch

Here I have to be straight with you: you can't fix this one at a farm gate this week. Turmeric mostly isn't a farm-gate product in Australia, and I won't pretend SideStall is full of spice growers. It isn't.

But the lesson travels well beyond turmeric. The protection was never a better label. It's a shorter chain and fewer processing steps between the plant and you. The rule I keep coming back to: wherever you can, buy things whole, from someone you can ask. A bulb of garlic can't be padded with filler. A fresh chilli can't be dyed to look like more than it is. Whole food carries its own proof.

Whole flavours, direct from the grower

• Haaseford Farms Garlic near Ironbank SA, a stall whose entire name is the specialty
• From the garden near Glass House Mountains QLD, which has listed chillies
• Couch Products near Freeling SA, likewise known for chillies with serious intent

And if you do grow ginger, turmeric or herbs for drying, this is me asking directly: list a stall. The trust gap this whole series is about is exactly the gap you'd be filling.

For the record: the turmeric findings come from the ABC's Four Corners program Duped: Food Exposed and its late July 2026 reporting. The turmeric findings have not been pinned to named brands in anything I could verify, so no brand is named here.
