Shun NagaiIf you are involved in the development or sale of pet food, you have probably heard the term “AAFCO standards” at least once. AAFCO, the Association of American Feed Control Officials, is widely recognized in the industry for establishing guidelines on pet food nutrition and labeling.
In particular, for a product to be marketed as complete and balanced, it generally needs to either meet AAFCO nutrient profiles or pass feeding trials. For this reason, many manufacturers use AAFCO standards as a benchmark.
However, AAFCO is not a certification body and does not have direct regulatory authority. Even so, why do manufacturers around the world place so much importance on AAFCO standards? And what role do these standards play in the Japanese market?
What Is AAFCO?
You may have seen the name “AAFCO” printed on the back of pet food packaging, but what exactly is AAFCO, and why does it matter?
AAFCO stands for the Association of American Feed Control Officials, a nonprofit organization that sets standards for pet food labeling, nutrient content, ingredient definitions, feeding trials, and laboratory analysis.
AAFCO supports animal health, safety, and welfare by creating nutrient profiles based on scientific research and laboratory testing. These profiles define the nutrients dogs and cats should consume. For example, AAFCO’s dog food nutrient profiles are supported by nutrient analysis and AAFCO-compliant feeding trials.
Does AAFCO Approve or Regulate Pet Food?
AAFCO does not have direct regulatory authority over pet food and does not “approve” manufacturers or recipes. That role belongs to regulatory agencies such as the U.S. Food and Drug Administration (FDA). Therefore, phrases such as “AAFCO-compliant cat food” or “AAFCO-recommended dog food” simply mean that the food meets AAFCO nutrient standards.
Although AAFCO does not directly test, regulate, or certify pet food, it works closely with the FDA and state authorities to help ensure that pet food is manufactured safely and labeled appropriately. FDA staff also participate in several AAFCO committees, especially the Pet Food Committee and the Board of Directors.
In addition, some U.S. states implement their own pet food regulations. For example, states such as New York may develop laws based on updates to AAFCO’s model bills and regulatory changes, although adoption is not mandatory and varies by state.
The Purpose of AAFCO
AAFCO’s guidelines are centered on pet health and nutrition. The organization also fulfills a number of important roles and responsibilities, including the following:
- Providing accurate information to pet owners and helping clarify questions about pet food.
- (AAFCO members are not practicing veterinarians, so they do not provide veterinary medical advice or treatment recommendations.)
- Establishing model regulations to help manufacturers provide clear and accurate information about animal feed, including pet food.
- Creating and maintaining AAFCO dog food and cat food nutrient profiles, which define the minimum required levels of essential nutrients.
- Setting standardized feeding trial methods. Pet food manufacturers may either formulate products to meet AAFCO nutrient profiles or conduct AAFCO-recommended feeding trials.
- Updating model bills and regulations to guide state regulatory authorities.
- Providing guidance on labeling definitions and standards to pet food regulators around the world.
- Holding training seminars, workshops, and events for regulators and manufacturers.
- Overseeing the ingredient definition petition process for new feed ingredients used in commercial animal feed products in the United States, based on a memorandum of understanding (MOU) with the FDA.
What Do AAFCO Standards Mean?
When AAFCO standards are stated on dog food packaging, it means that the product meets the essential nutrient profiles established by AAFCO.
This statement is found on nearly all U.S.-made dog food products. Since AAFCO is one of the most widely recognized standards in the world, it is also commonly referenced on products in many other countries, including Japan. The purpose of these standards is to confirm that the food contains all nutrients required for a specific life stage.
AAFCO defines life stages such as adult maintenance and growth and reproduction, and in recent years it has also introduced additional guidance for large-breed puppies.

How Compliance with AAFCO Standards Is Demonstrated
For pet food sold in Japan that claims compliance with AAFCO standards, the label may also indicate how nutritional adequacy was demonstrated. There are two main methods:
- Proof by Laboratory Analysis:
Under this method, samples of the pet food are analyzed in a laboratory to confirm whether the product meets AAFCO standards. If it does, the label states:
“This product has been proven, through analytical testing as defined by the Pet Food Fair Trade Council, to meet the standards for complete and balanced pet food.”
- Proof by Feeding Trial
In addition to laboratory analysis, this method verifies the nutritional value of the food through actual feeding trials with dogs or cats. When this method is used, the label states:
“This product has been proven, through feeding trials as defined by the Pet Food Fair Trade Council, to be complete and balanced pet food.”
Is AAFCO Certification Required in Japan?
Conclusion: No. Pet food sold in Japan is not necessarily required to meet AAFCO standards.
In Japan, pet food safety and related standards are regulated under the Pet Food Safety Act, which came into effect in 2009. Under this law, manufacturers must comply with standards established by the Ministry of Agriculture, Forestry and Fisheries and the Ministry of the Environment. However, unlike the United States, Japan does not have its own independent nutrient guideline system equivalent to AAFCO.
For this reason, many Japanese pet food manufacturers use internationally recognized standards such as AAFCO as a reference when developing products. Many products sold in Japan state that they meet AAFCO standards, but this does not mean they are certified by AAFCO. Rather, it means the manufacturer has independently demonstrated that the product satisfies those standards.
In addition, Japan’s industry body, the Japan Pet Food Association, refers to standards such as AAFCO and FEDIAF (the European Pet Food Industry Federation) while working to improve quality and safety within the industry.
Requirements for Labeling a Product as Complete and Balanced in Japan
Under Japan’s Pet Food Safety Act, there are certain conditions that should be met for a pet food to be labeled as complete and balanced, in order to ensure appropriate nutritional balance. These conditions are primarily intended to verify that the product provides balanced nutrition and satisfies relevant standards.
Conditions for Complete and Balanced Pet Food
- Compliance with AAFCO or FEDIAF Standards:
Japan’s Pet Food Safety Act does not specify detailed nutrient requirements for complete and balanced pet food. As a result, international standards such as AAFCO nutrient profiles and FEDIAF nutritional guidelines are widely used as practical references. Many products are formulated according to these standards in order to satisfy the requirements generally expected of complete and balanced pet food.
- Conducting Feeding Trials or Laboratory Testing:
To demonstrate that a product is appropriate as complete and balanced pet food, feeding trials or laboratory testing are commonly carried out. Feeding trials confirm nutritional adequacy by feeding the product to dogs or cats and monitoring their health status over time. If feeding trials are not conducted, laboratory analysis is generally used to verify that the product meets the required nutrient standards.
