A Las Vegas company and its owners have pleaded guilty to distributing a tainted ingredient used to make pet food that reportedly killed thousands of animals.
Sally Qing Miller, 43, her husband, Stephen S. Miller, 56, and their company, ChemNutra Inc., pleaded guilty to some of the charges contained in a Feb. 6, 2008, federal indictment.
The indictment alleged that the Millers and ChemNutra, along with two Chinese companies, brought wheat gluten tainted with the chemical melamine into the U.S. It was then sold to pet-food makers.
