With the development of the pharmaceutical industry, and consequently appearance of new substances which promote animal growth, the agricultural sector needs technologies more and more efficient and sensitive to detect possible residues left by this vast number of anabolic substances, mainly steroids with estrogenic, androgenic and progesterogenics activities. Such substances, when present in meat, fat, and eggs among others, can be detected and quantified by a series of methods, among the ones which we described the chromatographic methods, based mainly on gaseous chromatography coupled to the mass espectrometry (CG-MS), high performance liquid chromatography (HPLC), thin layer chromatography (HPTLC) and the immunological methods, as radioimmunoassay (RIA) and enzyme linked immunosorbent assay (ELISA). These methods have as advantages the high number of samples that can be analyzed by period of time, toghether with high sensibility and accuracy to detect anabolic residues.
