FDA’s list of facilities and registration documents are not subject to public disclosure. How do we know that a supplier, for instance, is registered?

Section 415(a)(5) of the FD&C Act provides that certain food facility registration information is
not subject to disclosure under FOIA. However, disclosure of such information by the facility
itself is not prohibited. FDA expects that generally, suppliers and their customers will resolve
this question as part of their agreement to buy and sell food for consumption in the United
States.
