A method for the analysis of lincomycin in porcine and bovine kidney.

A method of analysis has been developed for the estimation of lincomycin in porcine and bovine kidney. The method employed high performance liquid chromatography and Sep-Pak clean-up of methanolic tissue extracts and nitrogen specific gas chromatographic detection. Using spiked (0.1 mg kg-1) extracts recoveries in the range 40-50% were obtained. Analysis at the 0.05 mg kg-1 level is possible. Fifty four samples of kidney destined for UK sale were analysed for the presence of this drug. No samples were found to contain lincomycin.
