Concerns over adulterated dairy products have driven up China's imports of baby food and milk powder through the port of Shanghai.

Fang Yong, spokesman of the Shanghai Entry-Exit Inspection and Quarantine Bureau, said Wednesday that imports of baby food -- including diary products -- were up 32.5 percent by weight between September 15 and February 15, compared with the same period during 2007-2008.

The melamine scandal surfaced last September.

Shanghai port does not handle all of China's food imports, but it does handle one-fourth of China's trade.

The port also saw imports of whey powder leap 64.5 percent year-on-year by weight between January 1 and February 15. Whey is a protein powder made from cow's milk.

The rise in dairy-related imports contrasts with total food imports. For example, food imports via Shanghai port fell 27 percent year-on-year during the first six weeks of 2009.

China's leading diary producers are still feeling the fallout from the scandal, which involved adulteration of milk with melamine. The chemical, used to produce plastics and flooring, was added illegally to raise the apparent protein content of dairy products.

A nationwide investigation was organized after the scandal last year, when melamine-tainted milk powder sickened more than 294,000infants and killed at least six. The infants developed kidney problems because of the melamine.

A court in Shijiazhuang, capital of Hebei Province, declared February 12 that Sanlu Group, the diary producer at the heart of the scandal, was bankrupt.

Sanlu chairwoman Tian Wenhua was given a life sentence last month, and the group was fined 49.37 million yuan (about US$7.2 million) by the Shijiazhuang court for selling fake or substandard products.
