Food and feedstuff materials can contain pollutants that are naturally-occurring environmental contaminants that are present at low levels, particularly vegetable crops drawing nutrients directly from the soil. Alternatively, they may contain process contaminants that are introduced either during, or as a consequence of, treatment, carriage, manufacture and storage.

Food and feedstuffs that contain contaminant levels above the relevant Maximum Permitted Levels (MPL) are deemed to be unsafe and must be withdrawn and disposed of outside the food and feed chains, for example by sending it for alternative uses, for destruction, or returning it to the country of dispatch.

The ‘blending down’ of food and feedstuff materials with levels of contamination above the MPL, mixing them with uncontaminated materials to reduce the overall level of contamination to below the MPL has been prohibited since 2003.


PAH’s have been linked to various forms of cancer, therefore, the food and allied industries have a responsibility to ensure product safety.

This service meets the demands of the edible oils industry for both food and pharmaceutical use and complies with Commission Regulation 835/2011 which specifies the PAHs to be monitored such as: Benzo(a)Pyrene, Benzo(a)Anthracene, Benzo(b)Fluoranthene, Chrysene and their total.

The origin of contamination in oils includes environmental (both airborne and water) and various processing methods such as smoking, applied on foods during the manufacturing process.
