1) This applies to hydrogenated refined fats and oils.
Pesticide residues
According to Directive 90/642/EEC, European Maximum Residue Limits (MRLs) for processed products like oils and fats should be derived from the European MRLs for raw agricultural products. Concentration or dilution caused by processing must be taken into account. European MRLs for raw agricultural products can be found in the MVO-Fediol MRL database. For a number of specific oil-pesticide combinations Codex Maximum Residue Levels are set. These can also be found in the MVO-Fediol MRL database.
The reference method of analysis is NEN-EN 1528-1 /m 4. FEDIOL has a list with labs approved for analysing pesticide residues in oils and fats www.fediol.be/5/index3.php.

Bacteriological specifications 2) |
Legal limit | Codex limit | MVO guaranteed value | Reference Method of Analysis |
| Total plate count | max 1000/g | ISO 4833 | ||
| Salmonella | absent in 25 g | ISO 6579 | ||
| Yeasts | max 10/g | ISO 7954 | ||
| Moulds | max 10/g | ISO 7954 | ||
| Enterobacteriaceae | max 10/g | ISO 21528-2 | ||
| E. coli | absent /g | ISO 16649-2 |
2) Refined oils are sterile and have a too low moisture content for bacteria to affect the quality of the oil. However, during loading of means of transport contamination can occur. Bacteriological specifications should assure refined oils to be loaded according to good practices.

Mineral oils and thermal heating fluids
Strict legislation for the transport of refined oils and fats by sea and by land prevents the contamination of refined oils and fats with mineral oils.
There is no risk of contamination of refined oils with thermal heating fluids because European oils and fat producers only use steam heating. Refined (or semi refined) products from third countries are regularly checked on the presence of thermal heating fluids.
