| Abstract: | Carbofurane, a pesticide from the group of carbamates, has been employed against soil nematodes on a small meadow at the lake of Lugano, Switzerland. On the next morning, the first cases of death involving a total of 19 mallard ducks (Anas platyrhynchos) have been reported. By inhibiting the enzymatic breakdown of the neurotransmitter acetycholine, carbamates lead to excessive activation of the parasympathicus. In addition, paralysis of skeletal muscles is caused by continued stimulation of neuromuscular junctions. Death may occur by asphyxia. In the present case report, the diagnosis of poisoning could be confirmed by the chemical detection of carbofuran in the stomach, blood, muscle and kidney tissue of the affected mallard ducks. |
