Federal health officials are slapping a detention order on dozens of imported foods from China.
The Food and Drug Administration says foods made with milk will be held at ports of entry, as a precaution, until independent tests show they are free of the industrial chemical melamine.
The order, which also applies to pet foods, was posted on the FDA Web site Thursday. It's unusual for the FDA to detain goods from an entire country .
Unscrupulous companies in China have routinely added melamine to milk to artificially boost protein readings. The practice backfired after thousands of Chinese children got sick with kidney problems, setting off a global safety scandal. No illnesses have been reported in the U.S.
