I e-mailed the following question to the OU at kosherq@ou.org:
"I was wondering if R' Moshe Feinstein ZT'L's heter for Cholov Stam in the USA applies nowadays in Western Europe as well."
and I received the following answer:
"Thank you for contacting the OU.
One can rely on the heter of chalav stam in developed countries that have laws and enforcement.
However, one should really only buy milk that has hashgacha or is known to the local Jewish communities as being acceptable because of other possible issues at the factories.
Please do not hesitate to contact us again should you have any further questions.
Sincerely,
The Web(be) Rebbe
