Summary Traditional methods of microbial detection and enumeration of food poisoning micro‐organisms can take up to seven days. In this time a product with a short shelf‐life can be distributed, sold and eaten. There is, therefore, an urgent need for more rapid methods, preferably those producing results at least within an eight hour working day. This article discusses the rapid methods of detection and enumeration which are currently under development. In particular, antibody‐linked probes, DNA hybridization, the polymerase chain reaction and the lux gene system will be examined, with a view to indicating where major advances could occur.
