EU to implement new MOAH limits for olive oil

The European Union is set to implement new limits for Mineral Oil Aromatic Hydrocarbons (MOAH) in food products. For virgin and extra virgin olive oils, the regulation establishes an initial maximum level of 4 mg/kg, effective March 1, 2027, which will decrease to 2 mg/kg on January 1, 2028.

MOAH are petroleum-derived compounds that can contaminate food through lubricants, hydraulic fluids, and machinery used during production. While MOSH (saturated hydrocarbons) are generally not considered a major health concern by EFSA, certain MOAH fractions are flagged for potential genotoxic and carcinogenic properties.

Unifol (Unione Italiana Famiglie Olearie) has emphasized the need for prevention throughout the entire supply chain, from the olive grove to packaging. Research from the University of Udine suggests that while olives on the tree show low contamination, the most critical points for contamination are mechanized harvesting and milling due to potential leaks from hydraulic oils and lubricants. Unifol noted that its member companies already adhere to the 2 mg/kg threshold through systematic lot analysis, supplier qualification, and strict traceability.
