Abstract :
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.
