Cover Story: With the rise in prevalence of foodborne bacteria and contamination cases, on-site methods of pathogen detection offer an appealing alternative to traditional laboratory methods. In this work, we describe a strategy utilizing a dual detection of the genes of two Shiga toxin variants using a lateral flow strip platform to provide a broad assessment of the presence of Shiga-toxin-producing bacteria (STEC). This method is rapid, sensitive, and specific and is able to detect the presence of Shiga toxins in food samples. This strategy has the potential to be used in various steps of the food production chain to provide initial screening to ideally prevent infected product from reaching the hands of the consumer. View this paper
