White Castle Frozen Food Division Announces Voluntary Recall of a Limited Production of Frozen Sandwiches Sold in Select Grocery Outlets Due to Possible Presence of Listeria Monocytogenes

White Castle has initiated a voluntary recall of a limited number of frozen 6 pack cheeseburgers, frozen 6 pack hamburgers, frozen 6 pack jalapeno cheeseburgers, and 16 pack hamburgers, 16 pack cheeseburgers for the possible presence of Listeria monocytogenes.

Publication date: Available online 18 January 2020Source: IDCasesAuthor(s): Shawn Gerstein, Pranisha Gautam-Goyal, Sameer GoyalAbstractListeria monocytogenes is a gram-positive bacillus known to cause various human infections including central nervous system infections. The most common central nervous system manifestations are meningitis and rhomboencephalitis, however rare complications including hydrocephalus and intracerebral hemorrhage can occur and are associated with increased mortality and incidence of lasting neurologic sequelae. The mortality ranges from 17 % to greater than 30% in patients with neurological invol...

Springfield Smoked Fish of Springfield, Ma.is recalling its 1lb. packages Prescliced Nova Salmon because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea.

Springfield Smoked Fish of Springfield, MA is expanding their voluntary recall of smoked fish products because they have the potential to be contaminated with Listeria monocytogenes, an organism which can cause serious infections in young children, frail or elderly people, and others with weakened immune systems. Although healthy individuals may suffer only short-term symptoms such as high fever, severe headache, stiffness, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

Publication date: Available online 18 January 2020Source: Food ChemistryAuthor(s): Dongdong Jiao, Ying Liu, Ying Liu, Ruchun Zeng, Xiaoqin Hou, Guochao Nie, Lijun Sun, Zhijia FangAbstractA novel bacteriocin CAMT2, produced by Bacillus amyloliquefaciens ZJHD3-06, has potential as a natural biopreservative for the control of food-borne spoilage and pathogenic bacteria. To avoid interaction of CAMT2 with components of food that may adversely impact its antibacterial activity, CAMT2 was encapsulated into nanovesicles prepared from soybean phosphatidylcholine. The encapsulation of CAMT2 exhibited a limited impact on functional ...

This study demonstrates that there are limitations associated with the technology, and as a result the system may be unsuitable for measuring microbial growth rates in complex food matrices under the environmental conditions tested and within the time duration of the study.

The objectives of this study were to examine the stability of L. monocytogenes in non-fat dry milk (NFDM) during extended storage and further analyze thermal resistance of L. monocytogenes in NFDM under different water activities (aw) and its thermal stability after 1-year storage. We observed approximately 1.75 and 2.93 log CFU/g reduction of L. monocytogenes in aw 0.25 NFDM over 1-year storage at 4 and 22 °C, respectively. Thermal resistance of L. monocytogenes was inversely related to aw, and the inactivation kinetic curves of L. monocytogenes in NFDM at target aw showed a log-linear trend under all tested cond...

The objective of this study was to develop a unique quadruplex real-time quantitative PCR (qPCR) method able to differentiate the four most predominant and worrying L. monocytogenes serotypes (1/2a, 1/2b, 1/2c and 4b) in isolates from meat processing plants and ready-to-eat (RTE) dry-cured meat products. The design of specific primers and probes was based on the lmo0737, lmo0308, ORFC (locus genomically equivalent to gltA-gltB) and ORF2110 genes. A qPCR based on a fragment of the 16S rRNA gene was used to ensure the amplification of Listeria spp. genomic DNA. The standard curves showed efficiency values ranging between 92....

The objective of this work was to investigate the effect of stress conditions frequently encountered in food-associated environments on virulence-associated characteristics of eight strains of Listeria monocytogenes. Strains were grown at low (11 °C, cold stress) and optimal (37 °C) temperatures and in high NaCl concentrations (6% NaCl, 11 °C; cold-osmotic stress) and tested for their ability to invade the human intestinal epithelial Caco-2 cells. Results demonstrate that the correlation between exposure to cold stress and increased invasion phenotype is strain-dependent as strains investigated exhibite...

Abstract In the present study, we investigated whether cold plasma activation affected the efficacy of aerosolized hydrogen peroxide against S. Typhimurium and L. innocua. Stem scars and smooth surfaces of grape tomatoes, surfaces of Granny Smith apples and Romaine lettuce (both midrib and upper leaves) and cantaloupe rinds were inoculated with two-strain cocktails of S. Typhimurium and 3-strain cocktails of L. innocua. The inoculated samples were treated with 7.8% aerosolized H2O2 with and without cold plasma for various times. For all fresh produce items and surfaces, cold plasma significantly (P

Abstract We evaluated the bactericidal efficacy of the simultaneous application of ultraviolet-A (UV-A) irradiation and fumaric acid (FA) against Escherichia coli O157:H7, Salmonella enterica serovar Typhimurium, and Listeria monocytogenes in apple juice and as well as investigated the effects of this treatment on product quality. Further, we elucidated the mechanisms underlying their synergistic bactericidal action. Simultaneous UV-A light irradiation and 0.1% FA treatment for 30 min resulted in 6.65-, 6.27-, and 6.49-log CFU/ml reductions in E. coli O157:H7, S. Typhimurium, and L. monocytogenes, respectivel...
