A on the polymerase chain reaction (PCR) method based was developed for detection of Listeria monocytogenes in milk samples after enrichment culture. It consists of culturing samples in Listeria enrichment broth, followed by DNA extraction and detection of the organism using PCR. Dilutions of L. monocytogenes in milk were subjected to PCR amplification after enrichment culture. When determining the sensitivity of the method, it was found to be possible to detect 37 CFU (colony forming unit gl/ml) of the bacterium in milk. The method was assessed as a sensitive, specific, times-saving and practical way of detecting L. monocytogenes in milk samples.
