FDA and AAFCO-based state regulations require the product name, net quantity, guaranteed analysis (minimum crude protein and fat, maximum crude fiber and moisture), ingredient list in descending weight order, nutritional adequacy statement, feeding directions, and the manufacturer's or distributor's name and address. Imported products must also comply with country-of-origin labeling rules applicable to the retail format.

Raw and freeze-dried pet foods face heightened scrutiny because they may contain pathogens such as Salmonella or Listeria. FDA may subject these products to sampling and testing at the port of entry, and products from facilities with prior violations may be placed on automatic detention. Importers should confirm the foreign manufacturer's HACCP protocols and FDA compliance history before sourcing.
