Justification for type of information:
The brown algal seaweed is used in animal and human nutrition; in particular Ascophyllum nodosum is used as seaweed meal in Iceland, Ireland, Norway and UK. Animal nutrition: the most common seaweed source in animal nutrition in Europe is Ascophyllum nodosum; most data on its use are from Norway where it has been used since 1937. Human nutrition: the use in human nutrition is more common in Far East, particularly Japan, China and Korea, where the population eat more seaweed than in the West for both nutritional and industrial purposes. France is now the European country where seaweeds are used in human nutrition at the highest level. A. nodosum is used due to its ability to regulate bowel action, as source of amino acids and protein, vitamins and minerals and low fat content. Furthermore, seaweed extracts including Ascophyllum nodosum extracts are included in Annex I of Directive 91/414/EEC, which requires a reduced package of studies for Plant Protection Products made from plants or plants extracts (SANCO Draft Working Document 10472/2003/rev. 5). According to this document, for algal species used in food and feed, oral toxicity tests may be waived.
