Almost a year ago, the US FDA learned that certain pet foods were sickening and killing cats and dogs. An investigation by the FDA subsequently discovered contaminants in vegetable proteins imported into the United States from China and used as ingredients in pet food.
A portion of the tainted pet food was also used to produce farm animal feed and fish feed.
The FDA and the U.S. Department of Agriculture discovered that some animals that ate the tainted feed had been processed into human food. Government scientists have determined that there is very low risk to human health from consuming food from animals that ate tainted feed. All tainted pet food, animal and fish feed, and vegetable proteins continue to be recalled and destroyed.
As a result of FDA and USDA's comprehensive investigation, on February 6, 2008, FDA announced that two Chinese nationals and the businesses they operate, along with a U.S. company and its president and chief executive officer, were indicted by a federal grand jury for their roles in a scheme to import products purported to be wheat gluten into the United States that were contaminated with melamine.
