Additives and Contaminants
- Regulation 1831/2003 deals with additives for use in animal nutrition
- Directive 32/2002 and subsequent regulations deals with undesirable substances of animal feed
Feed AdditivesThe European Commission describes feed additives as products used in animal nutrition for purposes of improving the quality of feed and the quality of food from animal origin, or to improve animals’ performance and health.There are five general categories of feed additives:(1) Technological: that favorably affect the characteristic of feed, e.g. preservatives, antioxidants, stabilizing agents, emulsifiers, acidity regulators, and silage additives.(2) Sensory: that stimulate animal appetite, so that they naturally want to eat more– for example, colorants and flavoring compounds.(3) Nutritional: that provide a particular nutrient that may be deficient in an animal’s diet, such as vitamins, amino acids, and trace elements

Animal Feed Production: Feed Safety
Undesirable substancesBy definition, undesirable substances are any substance or product, with the exception of pathogenic agents, present in the product intended for animal feed which presents a potential danger to human health, animal health, or the environment, or could adversely affect livestock production.Thus, undesirable substances include many pollutants originating from human activities (e.g. dioxins); those naturally occurring in the environment (e.g. heavy metals or natural toxins produced by plants or fungi such as mycotoxins); and authorized feed additives when present in a non-target feed due to the unavoidable cross-contamination. This may occur when different types of products, for instance, feed containing coccidiostats in blank feed, are manufactured after each other in the same production line and traces of the feed additive are unintentionally transferred to the batches intended for species or categories not provided for in the additive authorization.Since it is impossible to fully eliminate the presence of undesirable substances, it is important that their content in products intended for animal feed is reduced to acceptable levels according to the concept of ALARA, as low as reasonably achievable, following good practices at all stages. Based on the scientific risk assessment related to the presence of a contaminant in feed performed by the EFSA panel on contaminants in the food chain, maximum levels and action threshold can be set in all products intended for animal feed.Maximum levels are concentrations of undesirable substances that, when exceeded, make products for animal feed non-compliant. While action thresholds are concentrations of undesirable substances below maximum levels that, when exceeded, involve investigations to identify the sources and steps to reduce or eliminate such sources, as in the case of dioxins and PCBs.Both feed additives and undesirable substances in products for animal nutrition are officially monitored in each member state under the Multi-Annual National Control Plan, in order to obtain an overview of the state of compliance with feed law and to surveille feed business operators and their activity.
