FDA says probing "thousands" of hogs for tainted feed

WASHINGTON (Reuters) - The U.S. Food and Drug Administration said on Tuesday that "thousands" of U.S. hogs might be affected by the agency's investigation of livestock feed contaminated with melamine.

"I don't have the numbers on that right now but it potentially affects thousands of hogs," Stephen Sundlof, director of the FDA's Center for Veterinary Medicine, told reporters. "Some of the hog operations were fairly sizable."

Livestock feed that may have been contaminated with ingredients imported from China was sent to hog farms in North and South Carolina, California, New York, Utah and "possibly" Ohio, he said.
