A state Department of Agriculture inspector will visit the Iowa feed mill where investigators found salmonella linked to the massive egg recall to check whether it is operating legally.
The mill, at Wright County Egg, hasn't been regulated by the state Department of Agriculture and Land Stewardship. Its owners say it qualifies for an exemption allowing farmers to make feed for their own livestock.
But the FDA reported Thursday that feed mixed at the mill was fed to chickens at Wright County Egg and Hillandale Farms in New Hampton.
State agriculture spokesman Dustin Vande Hoef says if the mill provided feed to other farms, it wouldn't qualify for the exemption. He says the inspector will visit next week to comb through its records.
The mill is among Iowa's largest.
