Mineral oils
Various food products are packaged in paper and cardboard, which often contain recycled paper. These packages may contain contaminants, for example from mineral oils in printing inks used in newspaper paper. These contaminants include aromatic hydrocarbons (so-called MOAHs) and saturated hydrocarbons (MOSH) derived from mineral oils. In June 2012, the European Food Safety Authority (EFSA) issued a scientific opinion, concluding that there is cause for concern, although uncertainties remain regarding the potential health effects.
