It's not actually a toxin in the egg whites, it's a glycoprotein called avidin, which binds to biotin (vitamin B7) and can result in a deficiency if an excessive amount of raw egg whites are consumed. However, egg yolks are a plentiful source of biotin and counteract the avidin, so as long as whole raw eggs are fed, it isn't typically a problem. But you're right, cooking the whites deactivates the avidin, so that would be the way to go if you wanted to be extra sure. Here's more info:
