"Christina McNaughton wasn’t sure where to begin looking when worrisome levels of arsenic turned up in two Utah County children last summer. The family’s water wasn’t contaminated. Not the soil either.
The trail eventually led McNaughton, a toxicologist for the Utah Department of Health, to the family’s backyard chicken coop — along with the eggs that came out of it, the feed that went into the hens that laid them and, finally, widely used animal-feed additives containing arsenic. ...
But the Utah study goes far beyond a Mapleton chicken coop. The use of roxarsone and other arsenic-based additives in poultry and swine feed is at the center of a national controversy."
