Dangerous?
Hi Ira. Any appliance that heats up is a potential source of fumes from a non stick coating, bread makers included. Even if the heating element is buried deep within the appliance, like a bread making machine. Contacting a knowledgeable person at the manufacturer ( which may prove very difficult in todays global economy) and getting the exact nature of any coatings used is essential. Your bread maker was likely made in China, like so much is these days, so that contact may take some perseverance!
We got one a few years ago and promptly gave it away.
