Dutch Authorities Find No Reason for Further Insecticide Probe

Toxicological research identified high concentrations of insecticide on the feathers of swallows found dead in two locations in the Netherlands. Previous theories regarding avian disease were ruled out after investigations failed to find a link. Researchers Avkessar Loos and Professor Niko are investigating the potential fatal consequences of these chemical concentrations. The findings follow a sudden spike in swallow deaths over recent years. The insecticide presence is being investigated as a possible cause of death for the birds. Investigators have ruled out diseases and internal bleeding as causes for the sudden mortality. The event is noted as being statistically unusual for the region. No specific chemical name or exact death toll was provided. The substance permethrin is used in anti-parasite products, while the use of tetramethrin is more restricted. Permethrin has broader authorization for certain applications, but it is not widely permitted for general agricultural use. The Netherlands Food and Consumer Product Safety Authority stated this week it sees no reason for further investigation into insecticide-linked swallow deaths.
