History
The Association of American Feed Control Officials (AAFCO) was founded in 1909 as the United States Feed Commission. Its original purpose was to bring together state officials responsible for regulating animal feed and to develop uniform standards that would protect both animals and consumers. In 1935 the organization adopted its current name, reflecting an expanded focus that now includes pet food, foodgrade ingredients, and feed labeling.
Over the past century, AAFCOs membership has grown to include representatives from all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands, as well as the Food and Drug Administration (FDA) and the United States Department of Agriculture (USDA). The organization meets twice a year, once in the spring and once in the fall, to review and update its model regulations, nutrient profiles, and ingredient definitions.
Mission & Vision
AAFCOs mission is to protect the health of animals and the public by developing and promoting uniform, sciencebased standards for animal feed and pet food. The organization pursues three core objectives:
- Safety: Ensure that feed products are free from harmful contaminants and accurately labeled.
- Nutrition: Establish minimum nutrient requirements that support the health of different animal species.
- Transparency: Provide clear definitions and labeling guidelines that enable consumers to make informed choices.
Its vision is a marketplace where all animal feed and pet food products meet consistent, highquality standards, regardless of where they are produced or sold.
Standards & Nutrient Profiles
AAFCO does not have regulatory authority; instead, it creates model regulations and nutrient profiles that state officials adopt into law. The most widely referenced documents are:
- Model Feed Act and Model Feed Regulation: Provide a framework for state feed laws, covering licensing, labeling, and enforcement.
- Official Publication: A semiannual compilation of regulatory updates, ingredient definitions, and nutrient profiles.
- Pet Food Nutrient Profiles: Minimum and maximum levels for essential nutrients in dog, cat, and other companion animal foods.
Each nutrient profile is derived from peerreviewed scientific literature and input from veterinary nutritionists. For example, the dog food nutrient profile specifies that adult dry dog food must contain at least 18% protein and 5% fat on a dry matter basis, ensuring a balanced diet for most healthy dogs.
Manufacturers that meet AAFCOs nutrient profiles can include the statement Formulated to meet the AAFCO Dog Food Nutrient Profiles on their packaging, a claim that many consumers recognize as a mark of nutritional adequacy.
Regulatory Role
Although AAFCO itself cannot enforce laws, its model regulations are adopted by every U.S. state and territory. State feed control officials rely on AAFCOs definitions to:
- Determine if a product can be labeled as complete and balanced.
- Set testing protocols for contaminants such as mycotoxins, heavy metals, and pathogens.
- Approve or reject new feed ingredients before they enter the market.
In addition to state adoption, the FDA references AAFCO standards when evaluating pet food safety under the Federal Food, Drug, and Cosmetic Act. This indirect influence helps harmonize federal and state oversight.
Industry Impact
AAFCOs work shapes virtually every aspect of the pet food and animal feed industry:
- Product Development: Formulators use AAFCO nutrient profiles as a baseline, then add premium ingredients or functional additives to differentiate their brands.
- Labeling Claims: Phrases such as AAFCOverified or meets AAFCO nutrient profiles are regulated claims that can only be used if the product passes appropriate testing.
- International Trade: While AAFCO is a U.S. organization, many exporters cite AAFCO compliance as evidence of high standards, facilitating entry into foreign markets that recognize similar benchmarks.
The organization also fosters transparency through its publicly available official website, which provides downloadable PDFs of the latest nutrient profiles, ingredient definitions, and model regulations.
Resources for Consumers & Professionals
Whether you are a pet owner, a veterinarian, or a feed manufacturer, AAFCO offers several tools that can help you make informed decisions:
- Official Publication (OP): Updated twice a year; includes all model regulations and definitions.
- Ingredient Definition Database: A searchable list of approved feed and pet food ingredients.
- Webinars & Workshops: Regular educational events covering topics such as nutrient adequacy, labeling compliance, and emerging safety concerns.
- Guides for State Officials: Practical handbooks that assist regulators in inspection, sampling, and enforcement.
For pet owners seeking to verify a products nutritional adequacy, look for the AAFCO statement on the label and crossreference the products guaranteed analysis with the appropriate nutrient profile for your animals life stage.
