Abstract
    Following a request from the European Commission, the Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) was asked to deliver a scientific opinion on l-histidine monohydrochloride monohydrate produced by fermentation with Escherichia coli (NITE BP-02526) when used as a nutritional additive or as a feed flavouring compound in feed and water for drinking for all animal species. The product under assessment is l-histidine HCl H2O produced by fermentation with a genetically modified strain of E. coli (NITE BP-02526). The production strain and its recombinant DNA were not detected in the final products. l-Histidine HCl H2O does not give rise to any safety concern to the production strain. The use of l-histidine HCl H2O is safe for the target species when used to supplement the diet in appropriate amounts. It is safe at the proposed use level of 25 mg/kg when used as a flavouring compound for all animal species. The use of l-histidine HCl H2O in animal nutrition raises no safety concerns for consumers of animal products. The additive is not irritating to the skin or eyes and is not a skin sensitiser. There is a risk for persons handling the additive from the exposure to endotoxins by inhalation. The use of l-histidine as a feed additive does not represent a risk to the environment. The additive l-histidine HCl H2O is regarded as an effective source of the amino acid l-histidine when used as a nutritional additive. For the supplemental l-histidine to be as efficacious in ruminants as in non-ruminant species, it requires protection against degradation in the rumen. It is also considered efficacious as a feed flavouring compound under the proposed conditions of use.
