Two Chinese businesses and an American company were indicted in the tainted pet food incidents that killed dozens of animals last year and raised worries about products made in China.

The Xuzhou Anying Biologic Technology Development Company; the Suzhou Textiles, Silk, Light Industrial Products, Arts and Crafts I/E Company, and Chemnutra Inc. of Las Vegas were charged in two separate but related indictments.  The indictments allege that Suzhou Textiles, an export broker, mislabeled 800 metric tons of wheat gluten tainted with the toxic chemical melamine to avoid inspection in China. Xuzhou then did not properly declare the contaminated product it shipped to the United States as a material to be used in food, the indictment says. It also says the shipment was falsely declared to the Chinese government in a way that would avoid a mandatory inspection of the company’s plants.
