The FDA issued warnings to three companies after discovering rodent, bird droppings and allergen hazards in their food facilities.

As part of its enforcement efforts, the Food and Drug Administration (FDA) sends warning letters to agencies under its jurisdiction. Some letters are not posted publicly until weeks or months after they are sent. Employers must respond to an FDA warning letter within 15 days. Warning letters are often not issued until the company has had months or years to resolve the problem. Typically, parts of the letter are edited so that they cannot be viewed by the public.

The FDA issued warning letters to three food operators for serious violations, including widespread rodent activity in nut facilities, bird droppings contaminating an onion packaging line, inadequate allergen management during roasting, and sanitation failures. The findings highlight the risks of sewage contamination, cross-contact with allergens and unsafe food entering the market.
