A collection of readily reproducible classic and emerging molecular methods for the laboratory isolation and identification of the pathogens, viruses, and parasites that cause food-borne disease. Among the pathogens covered are specific bacteria, including Salmonella spp, Campylobacter spp., Listeria spp., and Bacillus spp.; viruses, including noroviruses and enteroviruses; and parasites, including Cryptosporidium and seafood nematode worms. The protocols follow the successful Methods in Biotechnology™ series format, each offering step-by-step laboratory instructions, an introduction outlining the principles behind the technique, lists of the necessary equipment and reagents, and tips on troubleshooting and avoiding known pitfalls.
