Like Whole Foods, it looks like someone in the back room of Trader Joe's is hand-making gluten-free shelf tags. Whole Foods actually has way more GF products that TJ's, and for way more money. TJ's has products that look like they should be free of gluten but which have a suspicious-sounding CYA disclaimer about the possibility of allergen sneaking its way into the product. Even the GF markings on some products are accompanied by the statement "No gluten-containing ingredients," which is different than making a gluten-free claim and which leaves the door ajar for worrying about possible contamination.
All that said, the pre-fab Indian food pouches at TJ's are inexpensive and tasty, so I buy them despite all that. And I'm glad they now carry Udi's, though the price is just as high as everywhere else.
