Powdered Cholov Stam

If I drink only cholov Yisroel milk, may I consume powdered cholov stam milk?

This is a point of machlokes. Rav Zvi Pesach Frank zt"l (the Har Zvi) maintained that milk in powdered form is not included in the gezeirah of Chazalon cholov akum, but the Chazon Ish zt"l (on Yoreh Deah 115:1) strongly disagreed and held that powdered milk is included in the gezeirah. OU product that bears a Cholov Yisroel statement on its packaging has onsite hashgacha for the actual milking and does not rely on Rav Zvi Pesach Frank’s position.
