Scary melamin-milk crisis hits more global food companies

Some companies learned the need for extra diligence in China the hard way, during a spate of scandals last year from unsafe foods and toothpaste to melamine-laced ingredients in pet food.

But many continued to disregard the risks, said Jeremy Haft, a businessman who runs factories in China in a variety of industries, including medical products, clothing and building supplies.

"I don't think much was learned from the recalls of a year ago," said Haft, who has written of his experiences in a book, "All the Tea in China."

Tokyo-headquartered Lotte Group, a major snack maker, got caught up in the storm Friday after its popular chocolate-filled Koala cookies were recalled in Hong Kong and Macau because of melamine contamination.

Packages of the cookies, still on sale in Shanghai, list whole milk powder as an ingredient.

"We will look deeply into all the details of the manufacturing process," said Kayh Kim, manager of Lotte China Food's planning department in Beijing. "We really don't want to lose our customers' confidence."
