Is it permissible for Sephardim to have Chalav Nochri(Non-Jewish or Stam Milk)?

Greetings, 

1. Regarding non-Jewish milk – indeed, there is a prohibition against drinking non-Jewish milk if it was not supervised by a Jew; this is an established ruling in the Shulchan Aruch, Yoreh De'ah (Siman 115, Se'if 1). However, there are opinions that, in countries where the law forbids mixing different types of milk together, it is permissible to drink non-Jewish milk since the gentile is careful not to mix impure milk with pure milk. Others disagree, asserting that even in this case it remains prohibited to drink non-Jewish milk. From the halachic perspective, see Yalkut Yosef, Issur Veheter (Siman 81, Se'if 11), where it is proper and correct to be stringent and not drink non-Jewish milk except in cases of illness or for infants. Nonetheless, many Sephardim in the diaspora regularly rely on leniencies because it is difficult for them to be stringent, and they often cannot obtain Jewish-supervised milk. Those who rely on the lenient opinions have upon what to rely, even when not ill. 

2. Regarding non-Jewish milk powder – see Yalkut Yosef (ibid., Se'if 14), which states that non-Jewish milk powder mixed in chocolate and similar products (with rabbinic certification) is, in principle, not prohibited as non-Jewish milk after it is known that this powder is made from cow’s milk. It is permissible to eat such chocolate. However, it remains proper and correct to be stringent; but one may be lenient for children, even regarding sweets. 

Blessings, Hillel Meirs
