Detection of Sarcocystis spp. and Shiga toxin-producing Escherichia coli in Japanese sika deer meat using a loop-mediated isothermal amplification-lateral flow strip

[摘要] Game meat potentially harbors a number of parasitic and bacterial pathogens that cause foodborne disease. It is thus important to monitor the prevalence of such pathogens in game meats before retail and consumption to ensure consumer safety. In particular, Sarcocystis spp. and Shiga toxin-producing Escherichia coli (STEC) have been reported to be causative agents of food poisoning associated with deer meat consumption. To examine the prevalence of these microbiological agents on-site at a slaughterhouse, the rapid, simple and sensitive detection method known as the “DNA strip” has been developed, a novel tool combining loop-mediated isothermal amplification and a lateral flow strip. This assay has achieved higher sensitivity and faster than conventional PCR and is suitable for on-site inspection.
