Legal Definitions of Pet Food

Introduction

From a legal point of view, feed materials, compound (US: formula) feed, additives and premixtures have to be differentiated. A further split of compound feed into complete or complementary pet food (US: supplement) is done based on the nutrient content and the ability to fulfil the nutritional requirements except for water. Additional categories can be defined depending on the intended purpose of the product, e.g. dietetic petfood or milk replacer.

Feed Materials

Products of vegetable or animal origin, which are consumed by animals and contribute to energy and/or nutrients to the animal’s diet. Official names and definitions of permitted feed ingredients are given in the AAFCO Official Publication for the US and in the European Feed Catalogue for Europe, respectively. For declaration purposes, feed materials are allocated to specific categories and can be collectively declared as a group, e.g. oils & fats.

Feed for Pets

In the designation of feed for pets the expression ‘pet food’ is used.

Compound Feed

Compound feed consists of at least two feed materials, with or without feed additives.

Complete Pet Food

Pet foods providing all the nutrients in the amounts and proportions animals need are considered complete. Only complete pet foods are suitable for daily feeding without adding further food products except water. Nutritional standards for pet foods are provided by AAFCO in the United States and by FEDIAF in Europe. Nutritional standards for pet foods already established or under development in countries outside the USA and Europe are largely based on AAFCO or FEDIAF recommendations.

Complementary Pet Food

Complementary pet foods are designed to be only a part of the diet and they do not meet the known nutritional requirements when fed alone. They must be used in combination with additional food types to fulfil daily requirements.

Therapeutic/Dietetic Pet Food

Therapeutic pet foods are products with a specific nutritional profile intended for therapeutic purposes such as support of cardiac, kidney or liver function. Due to the specific intended use and functionality, products have to comply with particular nutritional characteristics and requirements for their declaration. In Europe, the range of application is laid down in a specific regulation. In other regions, products typically have to be individually registered by the manufacturer and approved by the local veterinary authorities before they can be put on the market.

Medicated Feed

Medicated feed is feed/pet food that (in contrast to dietetic pet food) contains veterinary drugs with a view either to restoring, correcting or modifying physiological functions by exerting a pharmacological, immunological or metabolic action, or to making a medical diagnosis.

Moisture Content Classification

By longstanding industry definition, manufactured pet food can be classified based on moisture content as follows:

• Dry food: ≤ 14% moisture
• Semi-moist food: > 14% < 60% moisture
• Wet food: ≥ 60% moisture
