Section 310(b) of the Federal Food,
Drug, and Cosmetic Act (the act) (21 U.S.C. 337(b)) authorizes
States to enforce certain sections of the act in their own names,
but provides that States must notify FDA before doing so. Section
100.2(d) (21 CFR 100.2 (d)) sets forth the information that a State
must provide to FDA in a letter of notification when it intends to
take enforcement action under the act against a particular food
located in the State.
