Concern for chametz and milk

Hi,

Regarding milk from a non-Jew's cow which was fed chametz on Pesach: One may use such milk on Pesach.

[I believe that this is only about the kashrut of the milk itself; one would not be permitted to consume or own any chametz that made its way into the milk.]

(Rav Moshe Feinstein, Igrot Moshe Orach Chaim 1:147)

Have a great day,
Mordechai
