The Gluten Free Certification Organization is an program of the Gluten Intolerance Group, a nonprofit organization. For a product to receive certification as gluten free, it must meet strict requirements, including testing under 10ppm (the US and Canadian legal limit is 20ppm, so this is even stricter.) Companies can apply to have their product qualify to use the GFCO label on their products if they meet the requirements.
Sometimes, companies use the label even when they have not been certified under the program, or their certification changes.
This week the Gluten Intolerance Group has an update on their site about products that are using the label, but do not meet the organization's standards. In addition, there has been some recent concern about the potential for gluten to be an undeclared ingredient in some spices imported from abroad, and they are working with the Canadian government to learn more.
