Listeria monocytogenes (LM) is recognized as an opportunistic, foodborne pathogen that leads to the disease listeriosis. Although the incidence of listeriosis is low, listeriosis has a high mortality rate. LM can survive the most common stresses present during food processing steps, and it causes contamination in many food products. Consequently, most countries have endorsed strong restrictions on LM in food products, especially in ready-to-eat products. Conventional culture-based methods are currently the gold standard for testing, but their inefficiency can no longer meet the needs of batch inspection. As a result, a sensitive, fast, and reliable method for LM detection is required. There are many rapid detection methods for LM that are based on different principles, and an overview of the methods of LM detection is addressed here, with an emphasis on chromatographic, immunological, and aptamer-based techniques. Additionally, the prospect of developing novel LM detection methods is discussed.
