摘要：
Pasteurised bovine milk from retail markets in the State of Sao Paulo, Brazil, was analysed for the presence of streptomycin (STP) and dihydrostreptomycin (DHSTP) residues. An ELISA kit was used for screening and a LC-APCI-MS/ MS QToF method for confirmatory analysis. Both methods were intra-laboratory validated and found suitable for screening and confirmatory testing, respectively, for STP and DHSTP residues in pasteurised bovine milk at concentration levels below the maximum residue limit (MRL) established for these substances (200 mu g kg(-1) expressed as the sum of the concentrations of STP and DHSTP). No residues of STP and DHSTP at detectable levels were found in the analysed samples (n 299).
