From the COR of Greater Detroit: Chateau de S. Martin Wines

Chateau de S. Martin Wines that bear a hologram with the certification of Rabbi M. Rottenberg are Kosher but NOT Mevushal. Some bottles incorrectly bear a sticker stating that it is Mevushal.
From The O/K: Kellogg’s Club Crackers

Kellogg’s Club Crackers bearing an O/KD are DE (dairy equipment). This should not be confused with Kellogg’s Club Crisps Baked Snacks, which contain actual dairy ingredients.
