What about bread crumbs? Do they need to be Pat Yisrael?

Yes, bread crumbs should be Pat Yisrael as well. There were poskim who were lenient regarding bread crumbs that are used for deep frying. This is because frying is a different process than baking and the deep frying is viewed as the completion of the bread crumb preparation (see Teshuvat Avnei Nezer Y.D. 100). Since this is a matter of dispute, unless there is a pressing need, Pat Yisrael bread crumbs should be used.
