From a Rav who has been quoted here by name from his Mishloach Manos (translated from Hebrew):
These items have been made with the intent of Kashrus, and even if something Assur fell in, it was “Aino MisKaven” and Mutar. Even if the Issur is the Rov, R’ Meir is Choshesh for the Miyut, and even according to the Rabbanan its Kavuah which is like Mechtza Al Mechtza, and since YOU can’t measure it, Min Hatorah it is Batul, especially because the Tzitz is Meratzah on food.
You could always add more Issur, and Yessr K’Natul Dami. Besides, I got paid for the Hechsher, and Hefsed Merubah makes things Vadai Mutar Lechulai Almah. Not only that, but we Pasken “Ein Berarah” (It makes no difference lit.), and there is Kavod Habriyos involved which is docha even a lo sa’ase.
One who is machmir should do so for others but be makel for himself and get drunk (as it states Yemini U’Semoli (my right & left)).
All this is done with a clear head, and I only come on the signature.
Harav Hagoan Nate Bar Nate.
Only a Gaon could write Purim Torah like this.
