Kroger issues a new listeria-linked recall

Kroger Co. is recalling another product after a supplier alerted the company of possible listeria concerns. The Cincinnati-based grocery giant (NYSE: KR) is recalling its Broccoli Raisin Salad because a supplier said sunflower kernels included in the package may be contaminated with Listeria monocytogenes, which could cause severe illness to individuals who consume it. No customer illnesses linked to the product have been reported to date. Kroger has removed the item from its shelves and alerted…

Henry Avocado Corporation is voluntarily recalling California-grown whole avocados sold in bulk at retail stores because they have the potential to be contaminated with Listeria monocytogenes. Henry Avocado is issuing this voluntary recall out of an abundance of caution due to positive test results on environmental samples taken during a routine government inspection at its California packing facility. There are no reported illnesses associated with this recall.

This study demonstrates a novel approach for synthesizing large-sized silver nanoparticles (AgNPs) using Angelica keiskei water extract. The AgNPs exhibited maximum absorbance at 438 nm and were mostly spherical in shape, with an average particle size of 130.1 ± 2.1 nm. The bacteriostatic and bactericidal effects of AgNO3 against the food-borne pathogen Listeria monocytogenes were explored by measuring the minimum inhibitory concentration and minimum bactericidal concentration. The antibacterial activity mechanism of the AgNPs was further investigated. The results show that the AgNPs could damage the membran...

Abstract Zoonoses such as Brucella, Mycobacterium bovis, Campylobacter, Salmonella, Escherichia coli, Listeria, etc. are spread by ingestion of contaminated unpasteurised milk products (from infected cattle) and result in infectious outbreaks, hospitalisations and mortality. In Southeast Asian countries, raw goat's milk is sometimes used for dengue infection-associated thrombocytopenia; however, evidence to support this sociocultural practice is lacking. A peak incidence of brucellosis cases may occur after a dengue season in communities where this practice is prevalent. PMID: 30895885 [PubMed - as supplied by publisher]

To investigate the role of fatty acid-binding protein 5 (FABP5) in infectious diseases, FABP5-deficient mice were challenged withListeria monocytogenes, a facultative intracellular bacterial pathogen. Interestingly, FABP5-deficient animals were able to clear the infection within 3 days whereas control wild-type (WT) animals showed comparatively higher bacterial burdens in the liver and spleen. Sections of infected tissues showed an increase in inflammatory foci in WT mice compared to FABP5-deficient mice. FABP5-deficient mice had lower circulating inflammatory cytokines and increased inducible nitric oxide synthase product...

WuAbstractTo increase the safety of fruits and vegetables, including blueberries, this study developed an efficient and practical treatment strategy that implements multiple antimicrobial wash “hurdles” using industrial realistic treatment times in combination with freezing (at −17 °C for 1 week) against Listeria monocytogenes and Salmonella Typhimurium on blueberries. To note synergistic effects of the sequential antimicrobial washes, a portable...

In this study, a Lactic acid bacteria (LAB), isolated from Vietnamese traditional fermented yogurt (Lactobacillus plantarum SC01), was encapsulated in alginate-gelatin (ALG-GEL) and the effect of incubation temperature, medium pH and surfactants were assessed. The aims of this research were to evaluate antimicrobial activity of bacteriocin produced by L. plantarum SC01. Another aim the research was to study the quality of pork meat treated with its Bacteriocin in 2 h as a bio-preservative at different storage times (0 h, 12 h, 24 h and 48 h) in room temperature, compared to control (treated with salt 40.0%). The antimicrob...

cute;rez OR Abstract Listeria monocytogenes is an opportunistic pathogen that is widely distributed in the environment. The evolution of its genome has exhibited differences in virulence among strains of the same species. Listeria monocytogenes LIPI-3 (Listeria Pathogenicity Island 3) and LIPI-1 (Listeria Pathogenicity Island 1) are considered responsible for the increased virulence in some strains. The aim of this study was to detect LIPI-1 genes and the llsX gene belonging to LIPI-3 in invasive strains of L. monocytogenes and to establish whether there is a relationship among the invasiveness, presence of the ll...

moud Sitohy The present work was carried out to determine the characteristics and antibacterial activity of 7S and 11S globulins isolated from cowpea seed (Vigna unguiculata (L.) Walp.). The molecular mass of 7S globulin was demonstrated by SDS-PAGE bands to be of about 132, 129 and 95 kDa corresponding the α/, α and β subunits. The molecular mass of 11S globulin was demonstrated by SDS-PAGE bands to be existed between 28 and 52 kDa corresponding the basic and acidic subunits. The minimum inhibitory concentrations MICs of 7S and 11S globulins isolated from cowpea seed were determined agains...

Abstract Listeria monocytogenes (Listeria) is a facultative pathogenic bacterium, and a sensitive method for specific detection of Listeria is considered of clinically significant. However, current approaches for identifying Listeria are time consuming or tentative, and especially, cannot identify bacterial viability and antibiotic efficacy, which are critical in establishing a treatment recipe. Herein, we have developed a nitroreductase (NTR) responsive fluorescent probe (NRFP) with a fluorescence off-on feature, which could rapidly detect Listeria in vitro and in vivo with high specificity and sensitivity. NRFP ...
