Yersl,
CHALAV ACHUM: is milk milked by a goy from a non kosher animal
CHALA STAM: is milk milked by a goy in unites states or in a place that has anan sihady which is a circumstance of evidence is equivalent to witnesses
in amercia we have anan sihady which a company states they r a comw milk company they have only milked milk from a cow because if they didnt and they would be fined so many ppl rely on this becausethere would be no point of any one statin that they are a cow milk company and not do as they say and get into trouble
CHALAV YISROEL: is milk milked from a cow with a masgiach watichin
THESE HALACHOS ARE ACCURATE THEY WERE JUST LEARNED FROM A RABBI WHO IS WELL VERSED IN THIS AREA!
IF U HAVE ANY QUESTION DONT BE AFRAID TO ASK!
