Several samples of goods found in Australian supermarkets labelled ‘gluten-free’ in fact contain gluten.

Researchers from the Walter and Eliza Hall Institute in Melbourne found detectable gluten in almost 3% of 256 of the most commonly purchased ‘gluten-free’ manufactured foods, a study published in the Medical Journal of Australia on Monday says.

A spokeswoman from Coeliac Australia says the organisation is taking the findings very seriously, and their research team is following up with the contaminated samples to ensure the issue is resolved.
