ABSTRACT:  Spectinomycin-contaminated bovine milk samples were assayed by liquid chromatographic (LC) and microbial receptor methods. LC involved a newly developed analytical method to quantitate the concentration of spectinomycin in the contaminated milk samples. The receptor assay used reagents and the reaction system used for the Charm II spectinomycin assay. Three standard curves (selected range, full range, and second-order polynomial) were plotted for the receptor assay and used to quantitate spectinomycin in contaminated milk samples. The levels of spectinomycin obtained by the receptor assay, using only the standard curve in the selected range, were comparable to the results obtained by LC analysis
