What is the ruling on purchasing milk from milk banks that buy milk from mothers and sell it to those who need it?

It is forbidden and impermissible to establish a human milk bank in this manner, because the mothers' milk will be mixed, and it will not be known who the [biological] mother is. Islamic Sharia prohibits through suckling what is prohibited through lineage. However, if the milk is from non-human sources, there is no objection to it.
