The use of HCH as a pesticide was banned in the EU since several years, but residues could be found even in present due to bioaccumulation and biomagnification in the environment. The goal of this paper is to emphasize HCH residues levels in feed and beef meat from a west Romanian county area. Conclusions: the highest pesticide residues levels in feed were those of γ- HCH, which are situated, as medium values, in national guidelines values, but not the Europeans ones; in beef meat, medium α, β and γ- HCH concentrations are situated both in national and European guidelines levels, excepted γ- HCH concentrations which exceed twice European standards; by reason of HCH isomers persistence in environment, pesticide feed residues have to be surveyed in order not to become contamination sources for animals and its, on their turn, considering bioaccumulation and biomagnification properties of organoclorine pesticides, contamination sources for man.
