چکیده

Almonds and peppercorns have been implicated in outbreaks of foodborne illnesses. The objective this study was to evaluate the efficacy gaseous chlorine dioxide (ClO2) for pilot-scale decontamination Salmonella, Shiga toxin-producing Escherichia coli (STEC), Listeria monocytogenes on almonds black peppercorns. Pathogens-inoculated were exposed ClO2 gas generated by mixing sodium chlorite (NaClO2) ferric chloride (FeCl3) dry form or dosing hydrogen (HCl) into NaClO2. concentrations (ppm) during treatment duration (h) recorded obtain cumulative exposure (ppm-h), reductions pathogen populations resulting from exposures determined. For almonds, increasing 983 10,408 ppm-h increased STEC, L. 1.1 4.1, 1.6 1.4 4.1 log CFU/g, respectively. peppercorns, 8039 3.0 6.0, 3.7 7.2, 3.2 7.3 A 4.0-log reduction pathogens achieved using 3112 Treatment parameters obtained could be used larger applications

Efficacy of antimicrobial compounds on surface decontamination of seven Shiga toxin-producing Escherichia coli and Salmonella inoculated onto fresh beef.

Several antimicrobial compounds have been used in commercial meat processing plants for decontamination of pathogens on beef carcasses, but there are many commercially available, novel antimicrobial compounds that may be more effective and suitable for use in beef processing pathogen-reduction programs. Sixty-four prerigor beef flanks (cutaneous trunci) were used in a study to determine whether...

Shiga toxin-producing Escherichia coli

Shiga toxin-producing Escherichia coli (STEC) cause hemorrhagic colitis (HC) and hemolytic uremic syndrome (HUS) in humans. Outbreaks are linked to bovine food sources. STEC O157:H7 has been responsible for the most severe outbreaks worldwide. However, non-O157 serotypes have emerged as important enteric pathogens in several countries. The main virulence factor of STEC is the production of Shig...

Prevalence of Multidrug Resistant Shiga Toxin-Producing Escherichia coli in Cattle Meat and Its Contact Surfaces

Background: Shiga toxin-producing Escherichia coli (STEC) are group of E. coli causing bloody diarrhea. The goal of this survey was to determine the prevalence of multidrug resistant shiga toxin-producing E. coli in cattle meat and its contact surfaces. Methods: Swab samples (n=120) were randomly collected from meat and contact surface of butchery shops in Sharkia province, Egypt. Prevalence o...
