Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens that cause mild or serious diseases and can lead to people death. This study reports the prevalence and characteristics of STEC O157 and non-O157 in commercial ground beef and environmental samples, including meat table, knife, meat mincing machine, and manipulator hands (n = 450)(More)
Shiga toxin-producing Escherichia coli (STEC) are recognized as food-borne pathogens. We developed and validated two SYBR green PCR (SYBR-PCR) and a real-time multiplex PCR (RT-PCR) to detect stx1 and stx2 genes in meat samples, and compared these techniques in ground beef samples from retail stores. One set of primers and one hydrolysis probe were designed(More)
Foodborne pathogens can cause acute and chronic diseases and produce a wide range of symptoms. Since the consumption of ground beef is a risk factor for infections with some bacterial pathogens, we performed a comprehensive evaluation of butcher shops, implemented improvement actions for both butcher shops and consumers, and verified the impact of those(More)
Shiga toxin-producing Escherichia coli (STEC) are foodborne pathogens, and beef cattle are recognized as the principal reservoir. The aims of this study were (1) to identify the most sensitive combination of selective enrichment broths and agars for STEC isolation in artificially inoculated ground beef samples, and (2) to evaluate the most efficient(More)
