| Oil safety criteria | Οil contamination with substances of varying toxicity degree |
|---|---|
| Pesticide residue control (450 active substances) | Contamination due to air & waterborne substance residues used as plant protection for growing olives or other neighboring cultivations |
| Pesticide residue control (200 active substances) | |
| Pesticide residue control (50 active substances) | |
| Benzo–pyrene | Contamination index from combustion processes that have occurred near olive trees or mills |
| Phthalates (plasticizers) | Contamination due to improper oil contact with unsuitable plastic hoses or plastic tanks and containers |
| Heavy metals (iron, copper, lead, arsenic, nickel, cadmium) | Contamination may be due to mechanical equipment and water used in the extraction of olive oil |
| Ηalogenated solvents | This type of contamination may occur in all stages of oil processing and packing |
