Cat food labels provide limited information regarding the nutritional value of the package contents. It is important for customers to know what can and cannot be determined from the label, and what information is particularly important. Major components of a pet food label include:
Values in the guaranteed analysis are expressed as either minimum or maximum. A maximum guarantee (% max) means at most this specific amount of the nutrient is included in the formula. A minimum guarantee (% min) means at least this specific amount of the nutrient is included in the formula. The following four nutrients must be included on all pet food labels:
For example, a cat food with a 25% minimum crude protein guarantee should contain at least 25% protein, but could contain much more. The only way to determine the actual amount is by laboratory analysis.
Other information may be guaranteed on cat food products, such as magnesium (% max), taurine (% min), ash (% max), and linoleic acid (% min).
Ingredients must be listed in order of abundance (largest quantity listed first).
AAFCO nutritional adequacy statements are required on all pet foods. Products may either be formulated or tested according to AAFCO procedures and recommendations.
Veterinary-exclusive products include statements such as, 'This product is intended for intermittent feeding only' and 'Use only as directed by your veterinarian.'
Manufacturing codes allow the company to track products for quality and inventory issues. In order to quickly and efficiently handle a customer inquiry, the company's customer service department will usually ask the customer for this code.
Expiration or 'Best Used By' dates are optional, but are helpful in determining product freshness and shelf life.
The manufacturer's information should include the company name, address, and phone number so customers can quickly and easily obtain product information.
A toll-free telephone number should be provided as a convenience to the customer and to ensure that a charge is not incurred when calling for information.
The Association of American Feed Control Officials (AAFCO) was formed in 1909 to establish a framework for uniform regulation of the feed industry. Although not a government agency, AAFCO operates within the guidelines of federal and state legislation including laws administered by the Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA).
AAFCO establishes standards or models for regulations aimed at ensuring that manufacturers provide clear, accurate, and consistent information about animal feed, including pet food.
Every year AAFCO issues an official publication called the AAFCO Manual. This manual, in addition to listing ingredient definitions and feed terms, addresses labeling issues such as label format, ingredient lists, nutrition claims, and guaranteed analysis.
These model regulations are different from laws. However a large number of state governments have adopted AAFCO pet food model regulations into state law.
The “AAFCO statement of nutritional adequacy or purpose,” also called a “nutrition claim” or “complete and balanced statement,” identifies which life stage and/or lifestyle the product has been approved for. Under AAFCO regulations, this statement must be substantiated by the manufacturer.
AAFCO recognizes three methods for substantiating the claim:
1. Laboratory analysis
2. Feeding trials
3. Analysis comparable in nutritional adequacy
AAFCO has outlined very specific protocols, or guidelines, for conducting feeding tests. The protocols specify test criteria including such things as:
Each life stage has its own protocol. Life stages are the same for both dogs and cats and are defined as:
A pet food with an 'All Life Stages' claim can be used from weaning through adulthood. This claim is considered an unqualified (absolute) representation of nutritional adequacy. If substantiated through feeding trials, the protocol for gestation/lactation and growth must be performed sequentially, using the same group of animals.
AAFCO regulations state that specific wording must be used when a diet is intended for special nutritional or dietary needs that require the involvement of a veterinarian for diagnosis, management, and follow-up.
Understanding the AAFCO statements for nutritional adequacy can help customers choose a high-quality diet that provides complete and balanced nutrition for the appropriate life stage of their dog or cat.
