MONDAY, April 30 (HealthDay News) -- U.S. health officials continued to reassure American consumers that pork products from hogs fed contaminated pet food were safe, even as reports surfaced that China has routinely added the contaminant melamine to its exported animal food supplements.

In a joint statement issued late Saturday, the U.S. Food and Drug Administration and the U.S. Department of Agriculture (USDA) stressed, "We are not aware of any human illness that has occurred from exposure to melamine or its by-products." They added that they have also identified no illnesses in swine fed the salvage food tainted by melamine, which was imported from China as an additive to wheat gluten used in dog and cat food.

Melamine, a derivative of coal, is at the center of the United States' largest pet food recall, involving more than 60 million packages of 100 name-brand products. The chemical has been linked to the deaths of at least 16 pets and the illness of possibly thousands of pets.

The USDA first announced on Thursday that meat from 345 hogs suspected of eating the contaminated feed had entered the U.S. food supply. Some 6,000 hogs suspected of eating the contaminated product have since been quarantined and meat from these animals would be withheld from the food supply, both agencies said.

In the Saturday statement, the FDA and the USDA said the possibility of human illness from eating swine exposed to melamine remains low for several reasons: "First, it is a partial ingredient in the pet food; second, it is only part of the total feed given to the hogs; third, it is not known to accumulate in the hogs, and the hogs excrete melamine in their urine; fourth, even if present in pork, pork is only a small part of the average American diet."

On Monday, The New York Times reported that Chinese producers routinely add melamine to wheat gluten and rice protein in animal feed products to falsely inflate levels of protein.

In interviews with agricultural workers and managers in China, the newspaper reported that animal feed producers have secretly added melamine to their feed for years because, during tests, it appears to be a protein, even though it doesn't add any nutritional benefits.
