Recent data on Ambrosia spp. seeds content in feed for wild birds in Slovenia

Vdihavanje peloda vrst iz rodu Ambrosia lahko povzroči preobčutljivostne reakcije. Krma za prostoživeče ptice je eden od dejavnikov, ki pripomorejo k širjenju omenjenih rastlin. Leta 2010 so zato k Direktivi o nezaželenih snoveh v živalski krmi (2002/32/ES) dodali aneks, da lahko krma za živali, ki vsebuje nezmleta žita, vsebuje do 50 mg semen vrst iz rodu Ambrosia v kilogramu krme (UL L 290/54). Podatkov o vsebnosti semen te rastline v krmi je zelo malo, zato smo z mikroskopsko metodo preiskali 40 vzorcev krme za prostoživeče ptice. Semena ambrozije je vsebovalo 20 vzorcev oziroma 50 %. Ugotovljeno število semen v kilogramu posameznega vzorca je bilo od 2 do 146 (10 mg do 774 mg). V skladu s predpisi smo vsebnosti preračunali relativno na vzorec z 12 % vlage in ugotovili, da je dovoljeno mejo presegalo 5 vzorcev (12,5 %).Inhalation of pollen belonging to the species of Ambrosia may cause hypersensitivity reactions. Feed for wild birds is one of the factors that contribute to the spread of these plants. For this reason an amendment to the Directive on undesirable substances in animal feed (2002/32/EC) was added, in 2010 stating that animal feed made of unground cereals can contain up to 50 mg of Ambrosia spp. seeds per kilogram (UL L 290/54). Due to the lack of data, 40 samples of feed for wild birds were examined with a microscopic method. Ambrosia spp. seeds were found in 20 samples (50%). The number of seeds was from 2 to 146 (10 mg to 774 mg). In accordance with the legislation, results were expressed relative to a feed with the moisture content of 12%. Five samples (12.5%) exceeded the permitted value
