Sundlof says that the fact that melamine has turned up in all three of these proteins lends "credibility'' to theories that it was intentionally introduced. "That will be one of the theories we will pursue when we get into the plants in China," he says. The FDA's Elder adds that, "the shipment of an adulterated product" is illegal under the Food, Drug and Cosmetics Act of 1938, and anyone found to be in violation of the law could face criminal prosecution and penalties.
According to Lora Sporny, a professor of nutrition education at Columbia University, protein is the only source of nitrogen in food. "Whenever someone looks at nitrogen in food, almost always they are looking at the amount of protein in food," she explains. Sundlof concurs, telling Scientific American yesterday that, "Traditionally the way that food firms have analyzed for protein is by looking for total nitrogen. Maybe that's something that needs to be changed in light of this outbreak."
According to Ron Salter, a vice president at Wilbur-Ellis, his company did an early spot check on a shipment of rice gluten from its new Chinese supplier shortly after hooking up with the company in the summer of 2006. He declined to comment on the depth of the analysis, other than to say that it checked for levels of protein ash, moisture and fiber. He says the rice gluten was purchased based on an agreed-on minimum amount of protein content, although, he adds, that he does not buy products based solely on protein concentration. "Definitely from here on, going forward,'' he says, "if we continue to go with anything from China, we will definitely be doing as many checks as we can."

Add CommentI no longer give my pets commercial dog food. I lost a dog to dry dog food that i thought was safe and good brand. i had an autopsy done and the path told me that he died of gas in the intestines caused by the food. I will never serve my dogs that any longer especially after i heard about the sarah palin incident with the turkey!! Apparently this is how commerical dog food is made, i make my own now with good ingredients like ground beef, rice veggies etc and supplement their diet with bread. i figure if it will not kill me it will most likely not kill them. they have been healthier and happier ever since.. i dont regret my decision they are worth it to me to cook for them, and i think in the long run this is cheaper than buying the food already made!!
