Lead poisoning was diagnosed in 5 (16.6%) out of 30 living anseriformes and in 4 (4%) out of 99 dead anseriformes presented at the Bird Clinic of the Veterinary Faculty of Ghent University in the period 1 January 2002 to 1 July 2004. Only two cases out of five could be treated successfully by chelation therapy. Because of the low number of patients, it was not possible to determine the actual incidence of lead intoxication in anseriformes in Flanders. Since in a number of suspected cases the owners did not consent to further examination, these figures should be taken as minimal estimates. Routine clinical examination of anseriformes presented with debilitation, apparent paralysis or anaemia of unknown aetiology should include blood sampling for lead determination in ducks, geese and swans. Diagnostically important features of two cases of lead intoxication in anseriformes treated at the Bird Clinic are described in detail in this short communication.
