Where It Comes From
Widely used on fruits, vegetables, grapes, cereals, turf, and ornamentals; small amounts can reach surface water [1][2].
How You Are Exposed
Eating treated produce or wine; inhaling spray or dust; skin contact when handling products or touching recently treated plants/soil; occupational mixing/applying [1].
Why It Matters
Generally low acute toxicity, but repeated high exposures can affect the liver and cause developmental effects in animal studies; EPA classifies it as not likely to be carcinogenic to humans [1][2].
Who Is at Risk
Farmworkers and pesticide applicators; pregnant people and young children; people who frequently work around treated plants [1].
How to Lower Your Exposure
Rinse and, when appropriate, peel produce; follow label directions; wear gloves, long sleeves, and eye protection when using; avoid treated areas until re-entry intervals; use integrated pest management to reduce need [1][2].
