A method for the residual determination of erythromycin in aquatic products has been established by using acetonitrile as an extractant. The sample was separated and purified by the following steps: fluid-fluid extract, solid phase extract and counter-extract. The method was sensitive and accurate. The detection limit was 200 fig/kg, the recovery was above 70% , and the relative standard deviation was below 10% .
