Organochlorine pesticide residues in bovine milk from León (Spain)

Residue levels of the organochlorine pesticides (α-HCH, lindane, heptachlor-epoxide, aldrin, endrin, dieldrin, o,p′-TDE, p,p′-TDE, p,p′-DDE and p,p′-DDT) were determined in raw bovine milk and compared with the maximum levels allowed by the European Union (EU) in these foods. The highest incidence percentage of the ten insecticides measured was for lindane, followed by α-HCH and aldrin. Moreover, the highest mean residue level was for α-HCH. None of the samples analyzed exceeded the maximum levels allowed by the EU.
