This is what I alluded to earlier. The government holds “chalav shenishtanu” isnt milk. I.e. milk derivatives are non-dairy. As far as halacha goes, (most hold that) derivatives of milk are milchig.
The OU therefore writes OU-D it is milching if somebody decides to ignore the OU’s clearly labeling it as dairy and instead to rely on the ingrediebnts or The FDS”s pesak that it is “non-dairy” why is that the OU’s problem.
I really sont understand theese people. I assume you are checking for a hechsher you see the OU you see the D which you know means the OU is telling you it is dairy (unless you call and they tell you otherwise) why would you listen to the company or FDA over the hashgacha?
