Gluten-free Cheerios under FDA review

The FDA is looking into Cheerios’ gluten-free label.

As a result of consumer complaints, the Food and Drug Administration is investigating whether General Mills’ Cheerios are following gluten-free labeling rules.

The FDA as of Tuesday had received complaints from 39 consumers who report they became ill after consuming Cheerios and Honey Nut Cheerios.

As part of its review, the FDA is collecting samples of the cereal from local retail supermarkets, said Dani Schor, R.D., of the communications and public engagement staff of the FDA Office of Foods and Veterinary Medicine.The agency can also request samples from consumers who filed complaints.

It’s unclear how long the FDA review of the cereal will take and when results will be made available.

“Each situation is different so we cannot predict the amount of time this may take,” Schor said in an email, noting that the FDA continually reviews complaints received by the agency. “The agency evaluates each report to determine how serious the problem is, and, if necessary, may request additional information from the person who filed the report before taking action. If a person reports an illness or injury that appears likely to be caused by an FDA-regulated product, FDA acts immediately.”

“We have conversations with FDA all the time. That’s routine. But we’re not aware of any specific actions taken recently by FDA relative to Cheerios,” Cheerios spokesman Mike Siemienas said  in an email. “I can tell you that we are confident Gluten Free Cheerios are safe and FDA compliant.”

The company has repeatedly tested the oats used to make the cereal, the flour ground from the oats and the final products. Five varieties of Cheerios are labeled gluten free-Original, Honey Nut, Apple Cinnamon, Frosted and Multi-Grain.

General Mills launched gluten-free Cheerios beginning in August, reformulating its iconic brand to be gluten-free by using oats that are mechanically processed to remove cross-contamination. Oats are typically cross-contaminated by gluten-containing wheat, barley and rye in the fields and during transportation, milling and processing.

Cross-contamination is of such great concern that only specialty oats that are grown and processed in a very precise way to prevent exposure to the gluten-containing grains were previously allowed on the gluten-free diet.

But  FDA labeling rules approved in 2013 consider oats to be a gluten-free grain and do not require food makers to use specialty oats in in products labeled gluten free. Instead, finished food containing oats has to meet the FDA standard of less than 20 part per million of gluten. FDA rules do not require companies to test their gluten-free products, but they are subject to the agency’s review and testing. Consumer complaints are one trigger for FDA review.

General Mills worked for 5 years to develop a method of removing gluten-containing grains from oats and built a 7-story, 50,000-square foot cleaning and sorting plant to process oats used in gluten-free Cheerios. The move to make the cereal gluten-free was initiated by Phil Zietlow, a longtime member of the Cheerios team who also came up with the idea for Honey Nut Cheerios. Zietlow, whose daughter-in-law has celiac disease, is featured in widely broadcast TV commercials for Cheerios.

The cereal has received mixed reaction from gluten-free consumers, generating social media debate. Some say they have gotten sick after eating Cheerios and question its safety. Others say they have eaten the cereal with no problem and are happy to have a mainstream, gluten-free product that’s reasonably priced compared to specialty brands.

Much of the debate followed a report by Gluten Free Watchdog, a Massachusetts gluten-free testing company. The company’s independent test of three individual boxes of Cheerios found the cereal met the FDA standard. But Tricia Thompson, R.D, the company founder, questions General Mills internal testing methods. She says  that because the company tests a composite sample of multiple boxes, higher levels in some could be diluted by lower levels in others. She recommends that those who have celiac disease not eat Cheerios and urges consumers with complaints to report problems to the FDA. You can  contact the FDA here.

Some consumers have said they would prefer that General Mills use specialty oats and get gluten-free certification from an independent, third party. The company has said the entire supply of specialty oats would be used up by Cheerios  in about two weeks. General Mills, which makes more than 800 gluten-free products including a number of Chex cereals, says its internal testing is thorough.

    I tried them and got an allergic reaction. Same with ego gluten free waffles. I think it is great that big names are recognizing gf needs, just do it right. I am not celiac, just wheat sensitive, so I hope people with more severe issues don’t get harmed.

  • Elizagal

    I have Celiac and have had no issues with these. Maybe folks having a reaction have more going on than Celiac or Gluten intolerence.

  • I interviewed Seaton Smith from GF Harvest LLC, a Gluten Free Oats company a couple weeks ago about this on my radio show, The Gluten Free Voice. Here’s the free podcast link:…/the-truth-about-gluten…
    We discussed both the purity protocol and the process of mechanical separation of oats (what Cheerios is using). I hope it helps folks understand the differences and the risks.

    Let’s also review gluten reduced beers. Just as many have gotten sick drinking those. There should be stronger warnings to the restaurant industry and stores.

    I am in AGONY as I write. Ate Gluten-free Cheerios this morning and am experiencing very painful esophageal spasms. So bad they double me over and make my head spin. That’s just ONE of the things gluten does to me. Thank you so much General Mills!

    I got sick too from honey nut cheerios. I have accidentally eaten a regular gluten item and not been in pain like I was with gluten free cheerios. I called the company, same time the recall was going on, they reimbursed me. They assured me these werent part of the recalled cheerios. Something rotten is going on!

  • Brittany O’Rourke

    I have celiac disease, and was delighted when these came on the market (Cheerios are one of the foods I had missed most). Around the time of the recall, I did get sick. However, I have been buying them since and eating them daily with no problems. Raising a family in a GF household is expensive, and this product has made a tremendous difference for both our food budget and morning routine. Thank you, General Mills!

    I work within many areas of coeliac disease from clinical to research and one needs to remember that not all with coeliac disease will exhibit symptoms when consuming gluten. Symptoms are NOT the basis of diagnosis and verification that a product is safe. All products should be tested to demonstrate that they meet the regulated standards, so that they are safe for those who do and don’t exhibit symptoms.
