Scary melamin-milk crisis hits more global food companies

The list of companies facing potential recalls grew Friday as reports of foods tainted with the industrial chemical melamine, which has been blamed in the deaths of four Chinese infants, spread to a widening range of products.

Food companies around the globe are rushing to assess their products and in some cases setting new strategies to prevent problems.

"We have to think about any processed food with milk or protein in it," said James Rice, a food industry veteran who is now China country manager for Tyson Foods Inc., the world's largest meat processor.

While his company is not affected, for others "that includes biscuits, cake mix, energy bars, anything that should have protein in it," he said.

Many food companies already were taking special precautions before Chinese milk suppliers were found to be adding melamine to watered-down milk to boost its apparent protein content. The chemical, which is high in nitrogen, can fool tests aimed at verifying protein levels. The compromised dairy products are blamed for sickening 54,000 children.
