In summary, 3.6% of GF labelled foods had a gluten content ranging from 5.8 to 554 ppm, of which 1.1% foods were above the regulatory threshold of 20 ppm of gluten. However, depending on the food category of the non-GF labelled foods, gluten was detected in 25.8% of foods, at levels ranging from 5.3 to 1566 ppm, with 19.4% of foods having a measured gluten content of greater than 20 ppm. The presence of oats in a majority of the foods with high measured gluten levels suggests that oats are a potential source of gluten-containing grains and should be analysed for gluten content before being used as an ingredient in food production. Overall, the results exhibit 98.9% GF labelling compliance for GF labelled foods. However, non-GF labelled foods, containing oats as one of the ingredients, or foods with gluten/wheat advisory statements, may be a safety concern for consumers with celiac disease or wheat allergy.
