<<Disclaimer: Verify this information before applying it to your situation.>> Hi! My wife and I are not celiacs, but our 36 year old Down Syndrome daughter is. It never occured to us in her first couple of years that the cross contamination possibllities within a toaster are atrocious. SOLUTION: An obvious one, but more than half of the Celiacs in our chapter had not thought of this. We bought a Toastmaster Pastry Toaster with four slots. Each side of two slots is separately controlled. We have labelled "gluten" and "non-gluten" with a black magic marker on each side pairs. I'm not pushing the brand as I'm sure there are many like this. If this fits you, it might be a good way to avoid cross contamination. Chuck F. in Tucson, AZ Chapter of CSA/USA.
