As part of its enforcement activities, the U.S. 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 generally have 15 working days to respond to FDA warning letters. Warning letters often are not issued until companies have been given months or years to correct problems. Portions of the letters are commonly redacted from public view.
The FDA has issued warning letters to four food businesses in California and Oregon after inspectors found persistent Listeria contamination concerns, seafood HACCP failures, produce safety violations, and time-temperature abuse involving ready-to-eat foods.
According to the agency, the violations could render products adulterated under federal law because they were prepared, packed, or held under insanitary conditions that may make them injurious to health.
