As part of its enforcement activities, the Food and Drug Administration 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 or years to correct problems. Portions of the letters are often redacted from public view.
The FDA has issued warning letters to four food importers in California, New York and Pennsylvania after inspectors found they failed to develop required Foreign Supplier Verification Programs (FSVPs) for imported foods.
