Description

technical field

[0001] The invention relates to a method for detecting food-borne pathogenic bacteria, in particular to a method for identifying food-borne pathogenic bacteria by using surface-enhanced Raman spectroscopy and cluster analysis. Background technique

[0002] Food-borne pathogens are one of the main causes of food poisoning, which not only lead to the occurrence of various human diseases, but also seriously threaten people's health and cause economic losses. The World Health Organization estimates that billions of people around the world are infected with foodborne diseases every year. After the "9.11" incident in the United States, great attention has been paid to bioterrorism incidents around the world, so it is imperative to establish identification and detection methods for foodborne pathogens. Generally speaking, pathogenic bacteria causing foodborne diseases emerge in endlessly, but Salmonella, Escherichia coli, Staphylococcus aureus and Listeria monocyto...
