Food Safety Publications

The Food Safety Publications tracks research that is published across national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. The research publications are tracked across six categories: Bacterial Pathogens, Chemical Contaminants, Natural Toxins, Parasites, Produce Safety, and Viruses. Articles produced by USDA Grant Funding Agencies and FDA Grant Funding Agencies are also tracked.

  1. Capsaicin Potently Blocks Salmonella typhimurium Invasion of Vero Cells

    • Mon, 05/16/2022 - 04:00
    • Antibiotics
    • Salmonella typhimurium (S. typhimurium) is one of the major food and waterborne bacteria that causes several health outbreaks in the world. Although there are few antibiotics against this bacterium, some of these drugs are challenged with resistance and toxicity. To mitigate this challenge, our group explored the ethnomedicinal/herbalism knowledge about a certain spice used in Northern Ghana in West Africa against bacterial and viral infection. This plant is Capsicum chinense (C. chinense).

  2. Surface-anchored liquid crystal droplets for the semi-quantitative detection of Aflatoxin B1 in food samples

    • Mon, 05/16/2022 - 04:00
    • Food Chemistry
    • Aflatoxin B1 (AFB1) is a common food mycotoxin that can cause various diseases. Therefore, reliable detection methods are required to ensure food safety against mycotoxins. In this study, we design a liquid–crystal (LC)-based assay for rapid detection of AFB1 in food samples. The surface-anchored LC droplets on glass (5CBSADrop) are obtained via a solvent evaporation method.

Generally, soil microbiota is classified as autochthonous or zymogenous organisms, based on their ability to survive in soil.

    • Mon, 05/16/2022 - 04:00
    • Food Chemistry
    • Mycotoxins contamination, especially aflatoxin B1 (AFB1) in edible oils, is a health hazard. Therefore, AFB1 trace analysis methods are urgently needed. Electrochemiluminescence (ECL) is a popular sensing method because of its low background interference and high sensitivity. However, existing ECL assays for AFB1 detection are based on aqueous rather than oil systems.

  6. Trivalent arsenic impairs the effector response of human CD4+ and CD8+ T cells to influenza A virus ex vivo

    • Mon, 05/16/2022 - 04:00
    • Food and Chemical Toxicology
    • Arsenic is a persistent environmental contaminant that humans are exposed to primarily through contaminated water supplies. Arsenic has been shown to have numerous immunomodulatory effects, including deleterious effects on T cell function. However, the effect of arsenic on human T cell function in the context of influenza infection remains poorly characterized.

  7. The impact of environmental pH on the gut microbiota community structure and short chain fatty acid production

    • Sun, 05/15/2022 - 04:00
    • FEMS Microbiology Ecology
    • Environmental pH is a critical parameter for maintenance of the gut microbiota. Here, the impact of pH on the gut microbiota luminal and mucosal community structure and short chain fatty acid (SCFA) production was evaluated in vitro, and data compiled to reveal a donor-independent response to an increase or decrease in environmental pH. The results found that raising environmental pH significantly increased luminal community richness and decreased mucosal community evenness.

    • Fish & Shellfish Immunology
    • As a kind of environmental pollutant, heavy metal Cadmium (Cd) exists widely in the environment. It is well known that Cd can accumulate and cause damage in liver, kidney and other organs. However, there are few studies on the immune cytotoxicity of Cd to fish. In particular, there are few studies on the toxicity of Cd to the head kidney lymphocytes of common carp. In order to further explore these mechanisms, we established an Cd exposure model in vitro.

    • Diagnostic Microbiology and Infectious Disease
    • The aim of the study was to describe the heterogeneity of the humoral immune response and pregnancy outcomes in infected women during an outbreak of toxoplasmosis. Forty-two pregnant women referred to the University Hospital of Santa Maria (HUSM), RS, Brazil in 2018 and 2019, were evaluated. Clinical symptoms were reported in 33.3% of the patients. The majority (64.3%) of symptomatic pregnant women had anti T. gondii IgM antibodies index >7.0.

  13. Vibrio cholerae Chromosome Partitioning without Polar Anchoring by HubP

    • Sat, 05/14/2022 - 04:00
    • Genes
    • Partition systems are widespread among bacterial chromosomes. They are composed of two effectors, ParA and ParB, and cis acting sites, parS, located close to the replication origin of the chromosome (oriC). ParABS participate in chromosome segregation, at least in part because they serve to properly position sister copies of oriC. A fourth element, located at cell poles, is also involved in some cases, such as HubP for the ParABS1 system of Vibrio cholerae chromosome 1 (ch1).

  14. Local and Global Protein Interactions Contribute to Residue Entrenchment in Beta-Lactamase TEM-1

    • Sat, 05/14/2022 - 04:00
    • Antibiotics
    • Due to their rapid evolution and their impact on healthcare, beta-lactamases, protein degrading beta-lactam antibiotics, are used as generic models of protein evolution. Therefore, we investigated the mutation effects in two distant beta-lactamases, TEM-1 and CTX-M-15. Interestingly, we found a site with a complex pattern of genetic interactions. Mutation G251W in TEM-1 inactivates the protein’s function, just as the reciprocal mutation, W251G, does in CTX-M-15.

    • New strategies are needed to fight the emergence of multidrug-resistant bacteria caused by an overuse of antibiotics in medical and veterinary fields. Due to the importance of biofilms in clinical infections, antibiofilm peptides have a great potential to treat infections. In recent years, an increased interest has emerged in antimicrobial peptides (AMPs). One of the richest sources of AMPs is represented by amphibian skin.

    • Direct-acting antivirals (DAAs) achieve high hepatitis C virus (HCV) cure rates and are forgiving to missed doses, but adherence–efficacy relationships have not been well defined. Traditional adherence measures (e.g. pill counts, self-report and pharmacy refills) over-estimate medication adherence. Newer technology-based tools have been used to provide more objective adherence data.

    • Duck salmonellosis is a common acute septic infectious disease that spreads rapidly, with serious harm to the duck breeding industry and public health. To date, there are few reports about the epidemiological characteristics of drug resistance in Salmonella from ducks. In this study, an epidemiological investigation was conducted on drug resistance of 110 Salmonella strains isolated from multiple duck farms in Shandong Province and surrounding areas, China.

    • Microbes and Infection
    • As a pathogenic microorganism, Listeria monocytogenes is widely used in the research of bacterial pathogenesis and host defense. The phagosomal escape of Listeria monocytogenes is essential for its replication in the cytoplasm of the host. Here, we reported that the protein abundance of the Six-transmembrane epithelial antigen of the prostate 3 (Steap3) was decreased upon Listeria monocytogenes infection compared to uninfected cells in macrophages.

    • International Journal of Food Microbiology
    • This study was aimed to examine the membrane damage mechanism of gallic acid (GA) on Yersinia enterocolitica BNCC 108930, and to explore whether GA can prolong the shelf life of pork. The minimal inhibitory concentration (MIC) of GA against Y. enterocolitica was determined by adopting the broth microdilution method. Second, an investigation was conducted on the morphological and physiological variations of Y. enterocolitica after the GA treatment.

    • In 2020, a new serotype of Vibrio parahaemolyticus O10:K4 emerged and caused several outbreaks and sporadic cases in Guangxi, China. Phylogenetic analysis indicated that those strains are new variants of the sequence type 3 pandemic clone. The new serotype may become dominant, warranting enhanced investigations and surveillance.
