Low Risk of Illness From Food Containing Melamine

The risk to human health is very low from eating meat from hogs and chickens that have been fed animal feed supplemented with pet food scraps containing melamine and related compounds, according to a risk assessment conducted by federal scientists. This conclusion supports the decision announced on April 28, 2007, not to recall meat from animals that were fed contaminated product.

The risk assessment is an important new science-based component of the continuing federal joint investigation into imported vegetable protein products from China that contained melamine and related compounds. Melamine is an industrial chemical that has no approved use in human or animal food in the United States.
