This chemical is already banned in Europe and Australia. 
Food bloggers and the public alike are celebrating the victory of  Vani Hari, founder of FoodBabe.com. After discovering that Subway  sandwiches featured an ingredient that was less than deserving of the  corporate “Eat Fresh” slogan, she collected over 50,000 signatures  demanding that Subway discontinue the use of azodicarbonamide. Subway  has announced that it will be discontinuing the use of the chemical  currently found in the sandwich-maker’s bread, but is also used in 
yoga mats, shoe soles and other rubber products elsewhere in the marketplace.
 Last year, Vani Hari, founder of FoodBabe.com, successfully  petitioned Kraft to remove the neon orange dye used in its macaroni and  cheese.  There has been no word from McDonald’s and other fast food  companies that are still using azodicarbonamide in their foods. My blog  “Disgusting Ingredients in McDonald’s Burgers” revealed that McDonald’s  is also using the potentially-toxic chemical.
 Azodicarbonamide is a chemical primarily used in the rubber and  plastics industries, as well as in some pesticides.  It is used as a  flour-bleaching agent that supposedly makes bread dough easier to work  with.  Lengthy exposure to the chemical has been linked to 
asthma.  The chemical industry’s own 
safety data sheets  show that it “may be toxic to kidneys” and that repeated or prolonged  exposure to axodicarbonamide “can produce target organ damage.” Yet,  somehow Subway, McDonald’s and other fast food makers have considered it  acceptable in their food products.  While these safety data sheets  reflect workplace exposures, surely the long-term effects of consuming a  chemical from the rubber industry warrants further investigation and  should never have been used in the food industry at all.
 In a statement to the 
Associated Press,  a Subway representative indicated that “The complete conversion to have  this product out of the bread will be done soon.”  The company hasn’t  given a date for which the chemical will be completely removed from its  food products.
 In an article with 
CBC News, Vani Hari said, “Their swift action is a testament to what power petitions can have.”
