MOSH and MOAH are the abbreviation of two groups of chemical compounds found in mineral oils. “MOSH” stands for Mineral Oil Saturated Hydrocarbons. MOAH stands for Mineral Oil Aromatic Hydrocarbons. Both of them are under European deeply evaluation because there are two food contaminants. According to the current state of scientific knowledge, there is no sufficient toxicological evidence to prove a health risk to humans from saturated mineral oil fractions (MOSH). Meanwhile, MOAH are suspected to be carcinogenic (especially PAH-like compounds with 3-7 ring systems), therefore their levels in food should be reduced according to the ALARA-principle (as low as reasonably achievable).
