MSNBC reported today that the wave of American pet deaths linked to contaminated food is bringing home a frightening new fact: China’s chronic food safety woes are now an international concern.

The list of Chinese food exports rejected at American ports reads like a chef’s nightmare: pesticide-laden pea pods, drug-laced catfish, filthy plums and crawfish contaminated with salmonella.

Yet, it took a much more obscure item, contaminated wheat gluten, to focus U.S. public attention on a very real and frightening fact: China’s chronic food safety woes are now an international concern.

In recent weeks, scores of cats and dogs in America have died of kidney failure blamed on eating pet food containing gluten from China that was tainted with melamine, a chemical used in plastics, fertilizers and flame retardants. While humans aren’t believed at risk, the incident has sharpened concerns over China’s food exports and the limited ability of U.S. inspectors to catch problem shipments.
