“Then people will eat it with fleishig”
That is the OU’s official reason for not having the DE hechsher. Some of us disagree with the argument, some Kashrus agencies decide differently.
I don’t personally see the kind of person who would willingly mix DE food and fleishig as being the type to post an “OU isn’t trustworthy thread” on the YWN forums. There’s a difference between the kind of person who might miss an OU alert here and there (ie. all of us) and the kind of person who would purposely eat DE with meat. Yes, it’s kind of a lose lose, but we all have the sides we’ve picked. The choice is between preventing willful transgression while risking accidental (OUD only) or risking willful transgression while preventing accidental (The case for DE).
Why would Nabisco want an OUD over a DE? Do they have any say?
