If a supermarket has a bakery on the premises that bakes bread and sells it to other stores in the same chain, is the supermarket required to register?

The supermarket is exempt from registration as a “retail food establishment” (21 CFR 1.227) if its
primary function is to sell food products directly to consumers from the supermarket. A retail
food establishment’s primary function is to sell food directly to consumers if the annual monetary
value of sale of all food products directly to consumers exceeds the annual monetary value of
sales of food products to all other buyers.
