>Talk about a major FAG alert.
Certain select short production runs of products are KFP (Kosher for Passover).
This high holiday warrants additional attention to production sanitation, specialized supervision to observe the cleaning and accordant payments (for the cleaning and supervision).
For a product to be KFP requires special supervision by the Rabbi which includes a intensive cleaning of the production line(s).
Daily Kosher products are Kosher but not at the super high level of observance as KFP.
