A recalled gluten-free flour actually contained wheat gluten, the FDA says

A plantain-flour ingredient sold as safe for the autoimmune protocol diet turned out to carry wheat gluten at levels the FDA says significantly exceed its threshold for a gluten-free label, prompting a recall of three GF Blends products. Truly AIP All Purpose Flour, Truly AIP Bread Mix and EAT G.A.N.G.S.T.E.R. Flat Bread Pizza Mix were pulled after independent testing of the plantain flour supplied by PMF Global turned up the contamination.

No illnesses had been reported as of Sept. 17, 2026, the date the recall notice went out. GF Blends sold the products nationwide through eatgangster.com, trulyaip.com and Amazon.com, and distribution continued through Sept. 12, 2026, before the company pulled the items.

A plantain-flour ingredient, not the branded flour, carried the gluten

The contamination did not originate in GF Blends’ own mixing process. According to the FDA’s recall notice, the wheat gluten traced back to a plantain flour ingredient supplied by PMF Global that GF Blends had folded into its own blends, and testing found contamination “significantly exceeding the FDA’s 20 ppm” limit for foods labeled gluten-free. Plantain flour, milled from a starchy banana relative, carries no gluten on its own, which is exactly why it is a common substitute base in autoimmune-protocol and gluten-free baking.

Cross-contact further up a supply chain is one of the harder gluten sources to catch. A finished product can test clean at a manufacturer’s own facility and still fail once an incoming ingredient carries contamination the brand never introduced itself, which is what an independent, third-party test caught here rather than routine self-testing at GF Blends.

The FDA’s 20 parts-per-million line, and why it exists at all

The FDA does not require a gluten-free product to contain zero gluten. Its final rule sets the ceiling at less than 20 parts per million, a number the agency chose because it represented the lowest level analytical testing could reliably detect when regulators wrote the standard, not because trace amounts below it are risk-free for everyone.

That threshold exists for people with celiac disease, an autoimmune disorder the FDA estimates affects up to three million Americans, in whom, according to the National Institute of Diabetes and Digestive and Kidney Diseases, the immune system reacts to gluten by damaging the small intestine — a condition managed only by keeping gluten out of the diet entirely, for life, since there is no medication that lets a celiac patient eat it safely. The rule covers fermented and hydrolyzed products too, categories where gluten content is harder to measure directly than in a simple flour blend, which is part of why GF Blends’ contamination was caught through outside testing rather than a label review.

A recall built on brand names most shoppers would not expect to overlap

Truly AIP All Purpose Flour and Truly AIP Bread Mix carry one label identity; EAT G.A.N.G.S.T.E.R. Flat Bread Pizza Mix carries an entirely different one. Both trace back to the same manufacturer and the same contaminated plantain-flour ingredient, a detail a shopper checking one brand’s recall history would have no reason to connect to the other without reading GF Blends’ name buried in the fine print. Truly AIP markets its mixes as being “sourced from a farm, not a lab” and compliant with the strict elimination phase of the autoimmune protocol diet, positioning aimed squarely at shoppers already avoiding hidden inflammatory ingredients — the exact audience least likely to expect wheat gluten in the bag.

The recalled lots span months of production, not a single bad batch. Truly AIP All Purpose Flour lots carry best-by dates into 2028, the bread mix’s lots run from April 2028 back to December 2027, and the pizza mix’s oldest recalled lot is dated with a best-by as early as July 2027, meaning affected packages sold as far back as last fall could plausibly still be sitting in a pantry rather than already consumed.

A refund, not a return, is what GF Blends is offering

GF Blends is telling customers to discard the recalled flour and mixes or return them to the point of purchase for a refund, rather than mail them back to a central facility. Consumers with questions have been directed to a company phone line staffed weekdays from 8 a.m. to 4 p.m. Pacific time, or an email address dedicated to the recall.

The FDA has not said whether PMF Global’s plantain flour reached other food brands beyond GF Blends’ three products, and no broader recall of the ingredient itself had been announced as of the notice’s Sept. 17 publication date. A single contaminated ingredient lot can sit inside more than one branded product line at once, which is exactly the scenario federal food-safety rules are meant to catch before an ingredient recall becomes several separate ones.
