Well, I'm off to China this week and it appears that it is not a moment too soon.

The Chinese firm whose baby formula is blamed for killing one infant and sickening dozens has accused dairy suppliers of adding a chemical to their milk to up protein content, state media said this morning.  Chinese authorities announced a nationwide probe today into the Sanlu Group's milk powder as babies fell seriously ill with kidney stones across the country, in the latest scandal to rock China's food industry.  One child has died.

Xinhua news agency said police in Shijiazhuang had arrested 78 "suspects" in the case, but gave no further information.  China's health ministry today ordered all its departments nationwide to immediately report every baby with kidney stones and difficulty urinating, symptoms of drinking the tainted milk formula.
