Two children in northern Utah were found to have toxic levels of arsenic in their blood– and the cause was eggs from their backyard chickens. The Utah Department of Health traced the source of the arsenic to commercial chicken feed made by IFA.
IFA insists that it does not add arsenic to its feed. UDH withdrew its report because it incorrectly assumed that the source of the arsenic was a chemical called roxarsone, and arsenic-based ingredient used in medicated chicken feeds. However, the agency stands by its conclusion that feed was the source of the arsenic, and notes that when the family switched feed the arsenic levels went down.
