Method based on matrix solid phase dispersion coupled to high performance liquid chromatography with ultraviolet detection was developed for the simultaneous determination of the three organophosphorus pesticides in beef and pork. The samples were extracted by matrix solid phase dispersion with acetonitrile -water(20:80, v/v), The analytes were separated and detected by HPLC -UV. Result: Spiked beef and pork 1.0 g/kg, 5.0 ? g/kg and 10.0 Ixg/kg. The method was validated and yielded recovery values between 82.2 % and 100.9 % and precision values, expressed as relative standard deviations ( RSD), which were less than or equal to 7.8 %, Linearity was good and greater than 0.9959 , and the limits of detection of the OPPs were in the range of 0.03 - 0.08 ~g/kg. Thus. the method is satisfactorily applied to the analysis of real samples and is recommended for food control.
