Background: Sea lampreys are parasitic fish found in lakes of the United States and Canada. Sea lamprey is controlled through manual application of the pesticides 3-trifluoromethyl-4-nitrophenol (TFM) and Bayluscide(TM) into streams and tributaries. 3-Trifluoromethyl-4-nitrophenol may cause irritation and central nervous system depression and Bayluscide may cause irritation, dermatitis, blisters, cracking, edema, and allergic skin reactions.
Objectives: To assess occupational exposures to sea lamprey pesticides.
Methods: We developed a wipe method for evaluating surface and skin contamination with these pesticides. This method was field tested at a biological field station and at a pesticide river application. We also evaluated exposures using control banding tools.
Results: We verified TFM surface contamination at the biological station. At the river application, we found surfaces and worker's skin contaminated with pesticides.
Conclusion: We recommended minimizing exposures by implementing engineering controls and improved use of personal protective equipment.
