Pesach Faqs

Q. May frozen or fresh breastmilk from before Pesach be used on Pesach?

A. Yes, but it should be stored in a Pesach (or new, disposable) container, because if it is kept in a chametz container the milk will absorb chametz ta'am/taste (via kovush) and become forbidden. The pump that you used to express the milk should not be washed together with Pesach dishes or in a sink that is kosher for Pesach.
