USA – White Wave, part of Dean Foods, has had to recall packages of its Vanilla Silk soymilk in nine states.

The recall came after it was discovered that some of the product may contain a caustic, sodium hydroxide based material used to clean and sanitise manufacturing equipment.

“We have isolated the manufacturing equipment malfunction that led to the problem, and have put additional safeguards in place to prevent this chain of events from impacting our product in the future,” said Steve Demos, president of White Wave.
