mdg: “A few years ago, I called a hand-Matza bakery, and the owner told me that most of the kneading of the dough is done by Goyim. He told me that most every hand-Matza bakery does this”
Matza made in this way does not fulfil the obligation of Shemura and one is not Yotzei with it the Kezeisim at the Seder. I have been to many bakeries both in the US an EY, and not one has goyim kneading the dough.
