Abstract
Foodborne pathogens are a continuous problem attracting the attention of public health institutions, microbiologists and food producers globally. The scientific community has therefore been focused for years on finding “new” and “better” methods, all in an effort to detect foodborne pathogens in the timeliest manner possible. It should be emphasized that the development of molecular genetics – the use of genetic information of biological macromolecules in routine testing in particular – has led to a revolutionary turn in biological science research. Almost all procedures detect different bacterial genetic footprint or biomarkers, which makes bacterial isolation unnecessary. However, these recent studies of “fast microbiological methods”, which require only a few
hours, rather than a few days, have not supplanted the classic way of microbiological food testing, i.e. the classic microbiological methods and the gold standard. The new methods are therefore faced with high requirements such as great detection limits, speed of analysis, relatively low costs and high sensitivity to identify various foodborne pathogens. Some of them provide the possibility of monitoring the pathogens, which is an important part of establishing a pathogen control network in the agri-food production chain at the international level. In this comprehensive literature review the authors present and review identification and quantification methods
with emphasis on the most important EU foodborne pathogens (Salmonella, Campylobacter, Escherichia
coli – STEC, Yersinia and Listeria). Methods have been divided into two large groups – Contemporary methods (Immunoassays and Polymerase Chain Reaction) and Novel approach methods (Biosensors, Bacterial typing, and Omics), and assessed by their functionality, advantages and disadvantages.
