96% of labeled gluten-free foods commissioned for
testing through Gluten Free Watchdog test below 20 parts per million of
4% of labeled gluten-free foods commissioned for
testing through Gluten Free Watchdog test at or above 20 parts per […]

A few musings this morning about testing food for gluten & the Nima Sensor. Background, I have been commissioning testing of gluten-free food for about 15 years. Does this make me an expert? No. I am a dietitian fortunate to have learned from the experts—the scientists who specialize in testing food for gluten, including the late Dr. Mendez (you may recognize his […]

The consumer sent all remaining product in the original container to Gluten Free Watchdog.
Gluten Free Watchdog sent the product to an […]
Article Summary: Gluten-Free Labeling: Are Growth Media Containing Wheat, Barley, and Rye Falling through the Cracks?
Gluten-Free Labeling: Are Growth Media Containing Wheat, Barley, and Rye Falling through the Cracks?
Tricia Thompson, Melinda Dennis, Luke Emerson. J Acad Nutr Dietet. 2017. In Press.
Background: Bacteria are used in a variety of products, including probiotics. These microorganisms may be grown on media that may include ingredients derived from gluten-containing grain (ie, wheat, barley, and rye). Historically, some concern has been expressed in the celiac disease community that the use of gluten-derived/ gluten-containing growth media may result […]
Gluten Free Watchdog recently received a question about the yeast used in a Crispin (Miller-Coors) hard cider certified gluten-free by GFCO. Neither GFCO nor Miller-Coors would disclose the growth medium used for the yeast.
Yeast testing: In an attempt to learn more about residual gluten protein in yeast grown on gluten-containing growth media Gluten Free Watchdog tested White Labs Pilsner Yeast cultured in a solution containing barley malt for gluten. This yeast is NOT labeled gluten-free. But, according to the […]
Lateral Flow Devices (Nima, Gluten Tox Home, EZ Gluten) to test food for gluten: Manufacturer & Consumer Use
This article was originally published in 2012 on glutenfreedietitian.com. Due to the marketing of the new consumer lateral flow device (LFD) NIMA there is a renewed interest in LFDs. An updated version of the article is republished here. If you are a manufacturer or consumer who currently uses or is thinking of using a LFD please take the time to read this article.
Thank you to Thomas Grace of Bia Diagnostics, www.biadiagnostics.com and Adrian Rogers of Romer Labs https://www.romerlabs.com/ for sharing their […]
The video is embedded below. First a recap of Nima testing to date …
Sampling methodology for Nima: Gluten Free Watchdog has been assessing Nima’s sampling methodology. Users are advised to place a small sample of food inside a disposable capsule. A small sample is defined as “pea sized.”
In the opinion of Gluten Free Watchdog, this sampling method is not well suited for testing packaged foods that may have heterogeneous (unevenly distributed) gluten contamination or restaurant meals with spotty cross […]
