Milk milked by a non-Jew came to be known as "''chalav akum''," which literally translates directly to "milk of a non-Jew," and milk that was properly milked in accordance with the law is known as "''chalav Yisrael'', literally "Jewish milk."

''Mashgichim'' are also responsible for ensuring that there is no opportunity for the milk to become non–''chalav Yisrael'' at any point before it leaves the facility.
''Chalav Yisrael'' comes into question regarding kosher cheese production, for, according to ''Chazal'', non-kosher animals' milk cannot be used to make cheese scientifically. Therefore, as noted by the
Star-K kosher certification, there are those who eat non–''chalav Yisrael'' cheese while still only drinking ''chalav Yisrael'' milk.
This position is also noted in the ''Mishneh Torah'', but the Rambam does not necessarily allow for it due to the sages' further prohibition of cheese of a non-Jew (''gevinat akum'').
