This is the kind of problem I'm referring to:

"Chemical scares and mass poisonings are common in China, which has been struggling to improve a dismal food-safety record. Manufacturers often mislabel food products or add illegal substances to them. Cooks routinely disregard hygiene rules or mistakenly use industrial chemicals instead of salt and other ingredients.

"Last year, seven companies were punished for using banned Sudan I dye to color egg yolks red. The industrial dye, a possible carcinogen used for leather, floor polish and other household chemicals, has been found in various consumer products sold in China, such as roasted meat, chili powder and lipstick.

"In 2004, at least 12 infants died from malnutrition after drinking formula with little or no nutritional value in eastern China's Anhui province."
