Giant Eagle Expands Recall of Sunflower Seeds Sold At Market District Stores

Giant Eagle supplier SunOpta has notified the retailer of a second expansion of the previously reported product recall on its sunflower seeds sold in the bulk section of three central Ohio Market District stores due to possible Listeria monocytogenes (Listeria) contamination.

uanghong Zhou As a natural potential resource, Tamarix ramosissima has been widely used as barbecue skewers for a good taste and unique flavor. The polyphenolics in the branch bark play a key role in the quality improvement. The purposes of the present work were to explore the polyphenolic composition of T. ramosissima bark extract and assess their potential antioxidant and antimicrobial activities. Hispidulin and cirsimaritin from T. ramosissima bark extract were first identified in the Tamarix genus reported with UPLC-MS analysis. Isorhamnetin (36.91 μg/mg extract), hispidulin (28.79 μg/mg extract) and cirsimar...

This study evaluated the fate of Listeria monocytogenes (Lm) on blueberries with different inoculation methods during antimicrobial interventions and subsequent refrigeration and frozen storages. Survival of Lm was highly dependent on the inoculation method. Dip-inoculated Lm was much more resistant to sanitizer interventions compared to spot-inoculated Lm on blueberries. In the storage studies, Lm on blueberries without sanitizer treatment maintained a stable population during both 4 and -15 °C storages regardless of the inoculation method or inoculation level. For dip-inoculated blueberries, there was about ∼0....

The objective was to assess UV-C radiation effect (13.44 W/m2) on microbiological decontamination and some quality characteristics of Cantaloupe melon juice, during refrigerated storage.Juice was inoculated with Listeria innocua (non-pathogenic surrogate of L. monocytogenes) and Alicyclobacillus acidoterrestris spores (spoilage indicators) used as indicators of the UV-C treatment efficacy. Total mesophylls and yeasts and molds were also enumerated. Results demonstrated that 5 min of exposure allowed 3.7 ± 0.3 log10 cycles reduction of L. innocua, while for A. acidoterrestris, 20 min were required to decrea...

In this study, probiotic Lactobacillus rhamnosus CECT 8361 was added to alginate-based coatings enriched with inulin and oligofructose and applied on fresh-blueberries. Probiotic viability, microbiological, physicochemical and sensory quality parameters of blueberries were monitored during 21 days of refrigerated storage. Also, L. rhamnosus CECT 8361 was tested for its antagonistic effect against inoculated Listeria innocua and E. coli O157:H7.Advantageously, prebiotic compounds allowed improving probiotic viability with counts above 6.2 log CFU/g for the entire period. Native microbiota counts remained under safe levels...

ete V Abstract It is well established that B cells play an important role during infections beyond antibody production. B cells produce cytokines and are APCs for T cells. Recently, it has become clear that several pathogenic bacterial genera, such as Salmonella, Brucella, Mycobacterium, Listeria, Francisella, Moraxella, and Helicobacter, have evolved mechanisms such as micropinocytosis induction, inflammasome down-regulation, inhibitory molecule expression, apoptosis induction, and anti-inflammatory cytokine secretion to manipulate B cell functions influencing immune responses. In this review, we summarize our cu...

CONCLUSIONS: As in other countries, the local neonatal LM incidence is low. Neonates present in the first week of life with severe disease and a high mortality rate. These data support a change in antibiotic policy, in keeping with international guidelines, limiting empirical ampicillin prescription to infants <1 month of age. PMID: 30645960 [PubMed - in process]

This study investigated the effect of four specific lineage I genes encoding surface proteins with internalin ‐like structures on cellular infection. Despite their association with lineage I, deletion of the four genes did not affect the cellular infection ofL.  monocytogenesST1, indicating that these genes may have other functions, either during the infection process or outside the host. AbstractListeriosis is a severe disease caused by the opportunistic bacterial pathogenListeria monocytogenes (L.  monocytogenes). Previous studies indicate that of the four phylogenetical lineages known, lineage I strains are ...
