As part of its enforcement activities, the Food and Drug Administration (FDA) sends warning letters to entities under its jurisdiction. Some letters are not posted for public view until weeks or months after they are sent. Business owners have 15 days to respond to FDA warning letters. Warning letters often are not issued until a company has been given months to years to correct problems. Generally, portions of the letters are redacted from public view.

FDA has issued warning letters to four food importers for significant violations of the Foreign Supplier Verification Program (FSVP) regulation. The FSVP rule requires importers to verify that foods imported into the United States are produced in a manner that meets applicable U.S. food safety standards.
