Epidemiological comments The Santoņa and Noja Marshes Nature Reserve is considered to be an area at special risk for the introduction of avian influenza, according to Order APA/2442/2006. Since 11 November and given the epidemiological situation in Europe, it was decided not to allow competent authorities to make exceptions to the measures to be applied in this kind of area. These measures are: a) Using birds of Anseriformes and Charadriiformes Orders as decoys is prohibited. (b) Breeding ducks and geese with other species of poultry is prohibited. (c) Rearing free-range poultry is prohibited. (d) Giving poultry water from water reservoirs accessible to wild birds is prohibited, unless water can be treated to ensure inactivation of possible avian influenza viruses. (e) Outdoor water reservoirs required for poultry welfare will be sufficiently protected against wild waterfowl. f) Poultry or other captive birds are prohibited in animal assembly centres defined in Article 3.7 of Law 8/2003 of 24 April on animal health, including livestock shows, exhibitions and cultural celebrations, as well as any concentration of poultry or other captive birds outdoors. In this respect, birds kept in premises authorised for sale to private individuals as pet birds, and poultry kept in commercial premises for subsequent retail sale to private individuals, will not be considered captive birds.
