The following information was provided to AMVAC via email by (name): On January 17, 2014, our enforcement staff responded to a call of dead and dying ducks in a harvested potato field in eastern (province). The officer collected 12 American Black Ducks and 1 female Mallard Duck. The ducks were found in a puddle, there had been a thaw and the field contained an open water source. Toxicology testing confirmed organophosphate toxicity with the organophosphate insecticide phorate being found in the samples submitted. Use records for that potato field indicated that Thimet had been used during the growing season. The investigation is on-going. We have also notified local PMRA staff. If you have any questions, please let me know. Thanks, (name), Manager - Pesticide Regulatory Program PEI Department of Environment, Labour and Justice (ph#) A wildlife diagnostic report on the 13 ducks was prepared by the Canadian Cooperative Wildlife Health Centre at the Atlantic Veterinary College, University of Prince Edward Island. They conducted a necropsy on each duck. Toxicology services were contracted to the Animal Health Laboratory at the University of Guelph. A summary of the necropsy and toxicology are provided in the attached report. The toxicology analysis included an organophosphate screen conducted by GC/MS. This is an open screen which compares the mass spectrum determined with a NIST library. Two compounds were detected; phorate and sulfotep. I have attached the spectrum for the sample, including a full scale chromatograph showing phorate peak, mass spectrum and Library match. The investigation at this time is still ongoing and we cannot release the specific location or the grower's name at this time. (name) Manager, tel: (ph#) email: (email name)

Mineure
AMVAC has not had the opportunity yet to review all details of what occurred since the investigation has not been finalized. Based on the information available to us today, the most plausible explanation due to the long length of time between likely application and event (over 3-4 months) is that some granules were not incorporated, either left on the surface at the end of the rows, or some sort of spill in the field. Granules that would have been incorporated would have been 6-8 inches below the soil and not available to the ducks to consume. This is supported by the reports that show possible granules in the ducks stomachs. Birds tend to feed at the end of rows so the most likely scenario seems the equipment was not stopped as the turn was made at the end of rows and some granules remained on the surface of soil and were not incorporated.
