Telegraph UK Recycled Paper Causes Cancer?

Breakfast cereal manufacturers are to stop using recycled cardboard in packaging after a study indicated that current boxes could pose a cancer risk.
Jordans — whose brands include Country Crisp and Crunchy Oats — has already stopped using recycled cardboard, while Kellogg's and Weetabix say they are taking steps to reduce the risk to human health.

The alert was sparked when researchers in Switzerland found that mineral oils in printing ink from recycled newspapers used in cardboard can get into foods — even passing through protective inner plastic bags.
