Since the effect of pesticides in birds has not yet been fully elucidated, in almost all worldwide diagnostic centers (including in Croatia) in assessing wildlife incidents most pathomorphological investigations include toxicological analysis in establishing the final cause of death. The most common cause of bird death, in which acetylcholinesterase - inhibiting pesticides/insecticides (the organophosphorous /OP/ and carbamate /CB/ products) have been identified, is a traumatic event (involving a static object, a vehicle or electrocution). In May 2019, the corpse of a male White stork (Ciconia ciconia) was delivered to the Laboratory of Pathology of the Croatian Veterinary Institute (CVI), Poultry Center (PC), Zagreb. The bird was found near a house in a small Slavonian village, where there was a nest with an adult pair and young birds. The owner testified about the sudden fall of the bird from the nest. X-ray examination did not show any traumatic lesions in the skeletal system or soft tissues, or the presence of ammunition. Apart from post-traumatic heart muscle and liver rupture lesions, an especially interesting gross lesion was the partally black colored, dark green content of unrecognizable texture in the gizzard cavity, and the black colored, rough and thickened cuticle under that part of the content. Toxicological finding: carbofuran and hydroxicarbofuran were found in the stomach content and in the liver. Although a toxin (carbofuran) quantification procedure was not performed, the fact that migratory birds may be particularly susceptible to the sublethal effects of insecticides (reduced movement, disturbed orientation) justifies our suspicion of the significant role of carbofuran in the traumatic event of affected bird. However, in assessing traumatic events affecting wild birds, the possibility of chronic lead intoxication must also not be overlooked. |
