Salmonella sp. and Escherichia coli Contamination on Cattle Beef from Binjai City Slaughterhouse and Tavip Market

Occurrence of Salmonella spp. and generic Escherichia coli on beef carcasses sampled at a brazilian slaughterhouse

A total of 120 beef carcasses were analyzed during processing at a slaughterhouse in southern Brazil. The carcasses were sampled by swab at three different steps of the slaughter line and then they were tested for Salmonella and E. coli. The Salmonella isolates were also examined for antimicrobial susceptibility. Salmonella prevalence distribution was modeled and the probability of contaminatio...

Super shedding of Escherichia coli O157:H7 by cattle and the impact on beef carcass contamination.

Beef carcass contamination is a direct result of pathogen transfer from cattle hides harboring organisms such as enterohemorrhagic Escherichia coli. Hide contamination occurs from direct and indirect fecal contamination in cattle production and lairage environments. In each of these environments, individual animals shedding E. coli O157:H7 at high levels (>10(4) CFU/g of feces, hereafter referr...

A Highlight for Non-Escherichia coli and Non-Salmonella sp. Enterobacteriaceae in Dairy Foods Contamination

Identification of Escherichia coli O157: H7 from Slaughtered Beef in Mashhad Using Biochemical and Molecular Methods

Background and Aims: Escherichia coli O157:H7 is one of the main causes of transmitted diseases by food, including meat and meat products. The purpose of this study was to investigate the prevalence of E. coli O157:H7 contamination in Mashhad with the detection of rfbE gene. Materials and Methods: For this study, 148 slaughtered beef samples from Mashhad (spring to winter, 2018) were randomly ...

Inhibitory Effects of Lactobacillus salivarius and Lactobacillus crispatus Isolated from Chicken Gastrointestinal Tract on Salmonella enteritidis and Escherichia coli Growth

Probiotics are live cultures of microbes; often lactic acid bacteria, but also some other species, which when fed to animals, improve their health and growth through altering the intestinal microbial balance. In the present research, healthy chickens’ gastrointestinal (GI) tracts were screened for the presence of lactic acid bacteria with probiotic properties. The probiotic properties of the is...
