In the present work we have developed a direct method (without enrichment) for the isolation of listeriae in milk, using the combinated action of SDS (sodium dodecyl sulphate), centrifugation and selective media. It is possible to identify even 0.5 listeriae/ml amongst 7.2 x 10(7) c.f.u. contaminants/ml
