The U.S. Food and Drug Administration has issued a document intended to help small businesses comply with regulations on declaring color additives in food for animals.

The document, entitled Small Entity Compliance Guide - Declaring Color Additives in Animal Foods, provides background and questions and answers on the 2011 regulation requiring that all color additives subject to the FDA's certification process be listed on the product label for animal feed or pet food. Color additives exempt from certification generally include those derived from plants or minerals.

All animal feed and pet food manufacturers must comply with the rule by November 18.
