Getting started with REX

REX searches food labeling and packing regulatory documents, citations and guidance from the FDA, USDA, and CFR at one time. You can search documentation by keywords and refine your results by date range,, document type (draft guidance, petitions, etc.), category (allergens, labeling, etc.), and more.
