Losses greater than 3% were incurred in a large flock of domestic geese on summer pasture. Necropsy of the sick birds revealed no significant bacterial or viral isolates. The trematodes Echinostoma revolutum and Notocotylus attenuatus were present in considerable numbers, respectively in the small and large intestines.
