I just heard this psak in the name of "the Rav". I suspect "the Rav" is Rabbi perlstein, based on who told it over, but I am not sure. I will try to find out.
They received some cans of corn that were labeled as being "Hetter Mechira" produce. Not knowing what to do with it, they went to "the Rav" to ask for a psak. He told them it is assur to eat, so they have to dig a hole in the ground, and pour out the contents of the cans into the hole, burying it.
