WASHINGTON (AP) - The government is exploring the theory that imported ingredients in some pet food may have been intentionally spiked with an industrial chemical to make them appear to have a higher protein content.
The Food and Drug Administration is looking into how the chemical, melamine, contaminated at least two ingredients used in more than 100 brands of dog and cat food. Melamine has been found in both wheat gluten and rice protein concentrate imported from China.
A California hog farm has been quarantined after melamine was found in pig urine there. It's believed to have come from rice protein concentrate imported from China.
So far, state officials say there is "minimal health risk" to anyone who has eaten pork from American Hog Farm.
