I posted an hour ago a post that is still awaiting moderation. It was a story about someone asking a well-known Gadol what to do with chalav stam chocolates they were given. He said they could give it away. To be more precise, he said “give it to me.”
L’maaseh, if someone is in this situation, they should ask a sheilah before assuming that it is okay to throw it out. That was my point.
If someone considers something assur it should certainly be okay to throw it out. But I am not sure that one could consider chalav stam to be in that category as Rav Moshe Feinstein zatsal permitted it. But I don’t know, so someone in that situation should ask.
