Gluten-Free Labeling

FDA issues a request for information regarding labeling and preventing cross-contact of gluten in packaged food

On January 21, FDA issued a request for information regarding labeling and preventing cross-contact of gluten in packaged food. The FDA reached out directly to Gluten Free Watchdog encouraging us to submit comments to help inform their decision-making process. According to the email received, the RFI seeks public comments and data on four main areas: Oats and gluten contamination through cross-contact with gluten-containing grains. Undisclosed ingredients where gluten sources may not be apparent to consumers (e.g., "malt extract" from barley). Consumer perspectives on gluten avoidance, purchasing decisions,...

Is the FDA enforcing the gluten-free labeling rule: You be the judge!

On October 1, 2024, the Food and Drug Administration updated the way in which consumers must go about reporting food-related issues to the agency. Instead of contacting an FDA consumer complaint coordinator, reports are now filed with the Human Foods Program either by phone or through the online safety reporting portal. Gluten Free Watchdog also was asked to use the portal. According to an email sent out by the FDA, “This streamlined process will expedite delivery of inquiries and complaints to...

Traditionally brewed soy sauce: Is it actually free of gluten peptides?

You may have read recently on social media that the Norwegian Celiac Association stated that traditionally brewed, wheat-based soy sauce is free of gluten and gluten residues. They joined Sweden and Finland in this assessment. For more information on what led to this conclusion, see https://ncf.no/glutenfri-mat/kosthold-og-ernering/vanlig-soyasaus-er-glutenfri-og-kan-brukes-av-de-med-coliaki Believe it or not, the FDA arrived at a somewhat similar but more conservative conclusion in the health hazard assessment they conducted on Chef Myron’s sauces containing wheat-based soy sauce. Gluten Free Watchdog asked...

Heartfelt Thanks and Gluten-Free Tidbits from FNCE

The honor of a lifetime: The Academy of Nutrition and Dietetics Food and Nutrition Conference 2025 recently wrapped. As some of you know, my main reason for attending the conference this year was to accept an excellence in practice award from the Academy of Nutrition and Dietetics for entrepreneurship (i.e., the work we do through Gluten Free Watchdog). It is thanks to all of you that this work gets done. As I said pretty much verbatim at the ceremony, receiving this...

Kirkland Signature Roasted Turkey Breast and Yeast Extract

Product warning for Kirkland Signature Roasted Turkey Breast. This product is labeled gluten-free and it contains yeast extract. Based on email correspondence with Costco, the yeast extract in this product may be brewer’s yeast sourced from the beer brewing process. (Brewer’s yeast from the beer brewing process is known as spent brewer’s yeast-- what’s left of yeast once it has been used to make beer. Consequently, spent brewer’s yeast may include gluten from malt and grain.) Correspondence from Costco: “Our supplier uses PHR-YL...

Manufacturers of Labeled Gluten-Free Food, Please Read

Dear manufacturers of packaged gluten-free foods… Ingredients the FDA designates as processed to remove gluten, such as wheat starch and glucose syrup (wheat), may be used in foods labeled gluten-free. BUT if wheat is declared in the ingredients list or a separate Contains statement as required under the Food Allergen Labeling and Consumer Protection Act... The word “wheat” must be “followed immediately by an asterisk (or other symbol) that refers to another asterisk (or other symbol) in close proximity to the ingredient statement...

Yeast extract confusion redux

In 2019, we wrote about a consumer complaint we received for a labeled gluten-free soup. The product includes the ingredient “flavors (including yeast extract).” Long story short, the consumer who contacted us was told by customer service representatives that brewer’s yeast is the source of the yeast extract. However, she did not receive a definitive answer regarding whether the brewer’s yeast is spent brewer’s yeast. Fast forward to 2024. Gluten Free Watchdog received a consumer inquiry about the autolyzed yeast extract...
