What about breakfast cereals? Must they be Pat Yisrael?

There are differing opinions as to whether Cheerios is considered pat. The OU poskim do not consider it pat, because of the size of the individual pieces and the manner in which it is made.  Likewise, wheat flake cereals and wafers are not considered “bread-like” and therefore do not need to be pat Yisrael. Corn and Rice Cereals are, by definition, not bread items.
