Post Consumer Brands Voluntarily Recalls Limited Quantity of Great Grains Protein Blend – Honey, Oats & Seeds Cereal Due to Possible Listeria Contamination

Post Consumer Brands is voluntarily recalling a limited quantity of its Great Grains Protein Blend – Honey, Oats &Seeds cereal because it contains sunflower seeds that have the potential to be contaminated with Listeria monocytogenes. The sunflower seeds were obtained from a supplier, SunOpta, which recalled its ingredient.

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 ...

This study explored the effectiveness of high pressure (200–500 MPa) alone or in combination with mild thermal treatments (35 and 50 °C) and nisin (25 and 50-ppm) on the inactivation of L. innocua and E. coli in carrot juice. Processing at 500 MPa at 20 °C for 2 min without nisin resulted in 4- and 5-log CFU/mL reduction of L. innocua and E. coli, respectively while incorporating 25-ppm nisin at same pressure and temperature rendered 7-log CFU/mL reduction. There was synergism between high pressure, nisin, and heat in all treatments to inactivate both microorganisms. After a 28-d of refrigerated sto...

This study explored the antagonistic activity of Lactobacillus rhamnosus GG (LGG) (Culturelle®), a commercial probiotic supplement, on foodborne pathogens and its heat sensitivity in soup products. Staphylococcus aureus, Escherichia coli O157:H7, Escherichia coli O104:H4, L. monocytogenes and S. Typhimurium were selected to assess the inhibitory effect of LGG on them and analyze their sensitivities towards LGG. Cream of potato (CP) and vegetable beef (VB) soups were selected as food matrix to determine thermal resistance of LGG between 55 and 62.5 °C. The effectiveness of LGG as a protective culture against the g...

This study is aimed to evaluate the efficiency of topical rosemary essential oil (REO) loaded into the nanostructured lipid carriers (NLCs) on in vitro antibacterial activity and in vivo infected wound healing process in the animal model. REO-NLCs morphology, size and in vitro antibacterial activity were done. Two circular full-thickness wound (each 6 mm) were made on the back of each mouse and each wound was infected with a solution containing 107 CFU Staphylococcus aureus and Pseudomonas aeruginosa. Animals were divided into four groups including control, Mupirocin® and two treated groups with a gel containing...

This study evaluated the thermal resistance of L. monocytogenes in cocoa powder and investigated the impact of water activity (aw) on its survival in cocoa powder. Natural unsweetened cocoa powder was inoculated with a 3-strain L. monocytogenes cocktail (∼9.0 Log10 CFU/g), equilibrated to aw 0.30, 0.45 or 0.60 at 22 °C and subjected to isothermal treatments. Survivors were enumerated to obtain thermal-inactivation parameters. L. monocytogenes population was stable in cocoa powder (aw 0.30) over the first month of storage, then decreased gradually but remained detectable after 12-month storage at 22 °C. ...

We investigated the synergistic effect of UV-C irradiation and ohmic heating on the inactivation of foodborne pathogens. UV-C irradiation and ohmic heating were applied to buffered peptone water and tomato juice inoculated with pathogens simultaneously or sequentially. A synergistic bactericidal effect of the simultaneous treatment was...
