apushatayid: Was it an oversight that you didn’t address the point made that Rav Moshe paskens that a baal nefesh should not eat C”S/CH”C and should only eat real C”Y? Rav Moshe clearly differentiates between the two.
As to your point, Rav Moshe issued a heter on how to satisfy Chazal’s requirement. It is not obvious without a heter that when Chazal say a Jew is required onsite that it can rather be satisfied with periodic inspections by a Christian FDA official.
