Proper clothes laundering lowers pesticide risk

Without proper safety precautions, pesticides may harm people. Farmers and others may become exposed to pesticides from residue on work clothing.

In a survey of pesticide applicators conducted by University of Minnesota Extension, only 15% of applicators said they follow pesticide labels for clothing selection. Because 45% of respondents had someone else wash their contaminated clothing, those family members may be exposed.

In Minnesota, certified private pesticide applicators can renew certification by participating in a Private Pesticide Applicator Training every three years or by passing an exam. In 2022, 1,994 people attended Minnesota Extension recertification courses, which included a module on the latest research and best practices for laundering pesticide-contaminated work clothing. Another 2,986 people completed mail-in or online exams. An additional 46 commercial/non-commercial workshops were held for 2,304 people.

In a follow-up survey, 85.5% of 1,064 pesticide applicators responded that they are able to determine the proper personal protective equipment before applying pesticides and how to properly clean, inspect and store the clothing and other gear after making applications. More importantly, 68% said they made changes based on the training.
