After extensive research, the only brand that seems to be safe for dairy, egg, peanut, and tree nut allergies is Cake Mate. And don't even ask about the conversation I had with Wilton and the overly intelligent service rep who only answered each question after I repeated it twice; suffice to say, Wilton cake decorations are not safe. Okay, back to Cake Mate. Please be advised, Cake Mate made by Signature Brands in the USA is NOT safe. Some of their products contain nuts and eggs. I am not sure how they label their products. However, Cake Mate made by McCormick Canada is safe. A quick phone call this afternoon confirmed that they are still manufacturing their cake decorations, sprinkles and icings in a facility that is completely peanut and tree nut free. Also, eggs and dairy are not even processed on the same lines. In addition, McCormick Canada lists allergens on their products. Some of the Cake Mate decorations have egg allergy warning on them, but according to the McCormick Canada rep they are processed in an entirely different facility. So just make sure that the version of Cake Mate you buy, lists McCormick Canada on the packaging. It will also list Signature Brands because both marks are used under licence, but if it lists only Signature without McCormick, then you may want to call Signature to confirm that the product is safe.
Here is the information for anyone wishing to call McCormick Canada and confirm allergen listing: 1-800-265-2600. Oh and if you get conflicting information please let me know. We're all in this together.
Good luck and happy decorating.
