Where It Comes From
Applied in fields, greenhouses, and packinghouses to control post‑harvest molds on produce; residues may remain on treated crops [1][2].
How You Are Exposed
Eating treated produce; skin contact or inhaling spray/mist when mixing, applying, or working in treated storage rooms; less commonly from nearby soil or water [1].
Why It Matters
Can irritate eyes and skin; high doses in animal studies affected the liver. Regulators set limits (including an acceptable daily intake) and EPA found no dietary risks of concern at approved uses [1][2].
Who Is at Risk
Farm and packinghouse workers; people who mix/load or enter recently treated areas; children (higher intake per body weight); people with liver conditions [1][2].
How to Lower Your Exposure
Wash and, when practical, peel fruits and vegetables; follow product labels; use gloves, protective clothing, and ventilation when handling; keep children and pets away until sprays dry [1][3].
