Pcr A Powerful Method In Food Safety Field

In this chapter, application of the polymerase chain reaction (PCR) technique in food safety, considering all the branches of this concept, is presented. The area of interest contains important analysis for both human health and the identification of food adulteration. PCR techniques used for detection of genetically modified organisms (GMO) in different matrices, identification of different animal species in meat and dairy products, as well as the detection of food infection with food-borne pathogens and toxicogenic fungi are described. The working methods and result analysis are exemplified, starting with DNA isolation adjusted to different matrices, detection of target genes, and validation for all of these methods. Techniques of simplex PCR, primer multiplexing, primer design, validation of the laboratory methods, optimization of the PCR results, and result interpretation through the analysis of the electrophoresis gels and sequencing data are studied. At the same time, the obtained results, the obstacles encountered, and how they were overcome could be an example for specific analysis developed with less resources and also for adapting the existent validated methods to the new laboratory conditions. The practical applicability and the consumer's demands are of great importance and always must be considered in developing and validating those methods.

The second section covers the use of real-time PCR to detect various pathogens including Salmonella, Listeria, E. coli, Campylobacter, Yersinia, Staphylococcus, Clostridium, viruses, and parasites. Also included is a chapter on the standardization of real-time PCR methods in food microbiology. In the final section, the book covers the use of real-time PCR for the analysis of genetically modified organisms, for food allergens, and for identification of animal or plant species. This will be an invaluable book for anyone involved in food microbiology or the detection of foodborne pathogens, and it is a recommended volume for all microbiology laboratories.

Molecular landscape for food safety analysis is rapidly revolutionizing because of high resolution and value added resulting analysis of next-generation sequencing (NGS) approaches.

Sequencing Technologies in Microbial Food Safety and Quality reviews several practices in that NGS contributes to foodborne pathogens functional characterization, management and control. This book focuses on potential uses of sequencing technologies in microbial food safety and quality and highlights present challenges in the food industry. Key Features: Application of whole genome sequencing technologies in disease diagnostics, surveillance, transmission, and outbreak investigation in food sector Impact of sequencing tools in the area of food microbiology Recent advances in genomic DNA sequencing of microbial species from single cells Microbial bioinformatics resources for food microbiology High-throughput insertion tracking by deep sequencing for the analysis of food pathogens This book includes contributions from experts who have manipulated sequencing tools in relation to microbial food safety and quality. Presenting comprehensive details about NGS approaches in food science, this book is an updated and reliable reference for food scientists, nutritionists, food product investigators to study and implement the sequencing technologies for developing quality and safe food. This book would also serve as informative resource for food industry officials, government researchers, food science or food nutrition students who seek comprehensive knowledge about the role of emerging sequencing technologies in revolutionizing the food industry.

This book will introduce non-molecular biologists to diagnostic PCR-based te- nologies for the detection of pathogens in foods. By the conclusion of this book, the reader should be able to: 1) understand the principles behind PCR including real-time; 2) know the basics involved in the design, optimization, and imp- mentation of PCR in food microbiology lab setting; 3) interpret results; 4) know limitations and strengths of PCR; and 5) understand the basic principles behind a new fledgling technology, microarrays and its potential applications in food microbiology. This book will provide readers with the latest information on PCR and microarray based tests and their application towards the detection of bacterial, protozoal and viral pathogens in foods. Figures, charts, and tables will be used, where appropriate, to help illustrate concepts or provide the reader with useful information or resources as an important starting point in bringing molecular diagnostics into the food microbiology lab. This book is not designed to be a “cookbook”PCR manual with recipes and step-by-step instructions but rather serve as a primer or resource book for students, faculty, and other professionals interested in molecular biology and its integration into food safety. v Table of Contents Preface . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . v Chapter 1.

Food safety and quality represent a major concern worldwide, not only for the potential risk to consumers’ health but also for the economic losses occurring in food industries. A complete quality system involves raw matter, environmental conditions, production processes, storage and distribution, taking into account the purpose for which the end product is intended. Appropriate analytical methods combined with good hygiene practices are essential to ensure a safe food supply and/or to minimize the occurrence of foodborne outbreaks due to the consumption of food contaminated with pathogens such as bacteria, fungi and parasites. On the other hand, the lack of measures able to detect quality deterioration, spoilage, authenticity and adulteration, as well as texture, rheology and sensory properties of food can affect the food industry economy and reduce consumer confidence. The use of rapid analytical methods can benefit food companies in saving time and cost, indicating the importance of developing new reliable assays for good and fast control of products throughout the whole food chain.
