The Chicago Tribune has done some investigating and has found that food labeled gluten free, such as Wellshire Kids' Dinosaur Shapes Chicken Bites, actually contain gluten:
The Tribune recently bought the Chicken Bites at a Riverforest supermarket and sent the samples to one of the nation's leading food-allergy labs, at the University of Nebraska. Both times, the lab found gluten. The item remains on shelves across the U.S.
The article future explained that:
The FDA doesn't define "gluten free," but generally "free" means a product contains none of the substance in question. The FDA has proposed adopting a 20 parts per million standard. In July, an international health commission recommended a similar standard.
The USDA, which has jurisdiction over meat products (including those below), has no policy specifically addressing "gluten-free" claims. The agency OKs labels before products go to market.
Gluten found in 'gluten-free' products
The Tribune bought three popular Wellshire Farms products advertised as "gluten free" and sent multiple samples to a lab for testing.
Chicken Bites: Tested at 204 parts per million and 260 ppm
Chicken Corn Dogs: Tested at 116 ppm and 2,200 ppm
Beef Corn Dogs: Tested at 191 ppm and 1,200 ppm
Wellshire Farms provided the Tribune with its own testing results, conducted in the spring. Their results showed: chicken nuggets tested at 200 ppm, chicken corn dogs 150 ppm, and beef corn dogs 120 ppm.
The following Sunday they wrote a second article Whole Foods claims to use "good manufacturing practices" to seperate allergens.
Don't know about you but I found this to be highly disturbing!! Regardless of labeling laws, everyone in the celiac community knows that the standard is 20 parts per million.
