A Salisbury company on Tuesday touted its launch of the world's first gluten-free crab cakes for commercial sale. Handy International, which has been in the seafood business since the early 1900s, said the crab cakes were certified by the Gluten-Free Certification Organization, an independent auditing body. Millions of consumers are adopting gluten-free diets to avoid certain types of cereals which could be damaging to the gastrointestinal system or cause allergies. Those who suffer from celiac disease, an autoimmune disorder of the small intestine, also may adopt a gluten-free diet. Handy's crab cakes are being sold at Costcos, Whole Foods Markets and other retailers across the country, or they can be ordered direct from Handy at http://www.glutenfreecrabcake.com.
