Food Manufacturers Change Packaging Because Of Concerns Over Tainted Recycled Cardboard

Health worries over boxes manufactured from recycled cardboard have led food manufacturers in Europe to change their product packaging, the BBC reports. Toxic chemicals known as mineral oils, used in printing inks in recycled newspapers, were discovered in some boxes by researchers who said the chemicals had contaminated the food they contained. Some firms have stopped using recycled cardboard completely, while others are making sure the boxes they use are not tainted by mineral oils, which have been associated with inflammation of internal organs and cancer. Swiss government scientists who analyzed pasta, rice and cereals sold in cartons manufactured from recycled cardboard found mineral oil levels ten to 100 times higher than recommended limits.
