How about a recall?
My guess would be that the OU does not have the power to demand a recall.
In any event, if you’re going to avoid the OU, then you’ll have very few options to eat. The OU not only supervises OU foods and establishments (obviously), but is used by many, many other hechsheirim (both in manufacturing of foods and eateries) for ingredients and such.
just with basar b’chalav?
Oh, please. This is not a case of basar b’chalav — it’s not as if the chips themselves were cooked with meat — they’re still 100% kosher. In addition, very few, if any people, are going to cook their potato chips with meat.
