Research Publications (Food Safety)

This page tracks research articles published in national and international peer-reviewed journals. Recent articles are available ahead of print and searchable by Journal, Article Title, and Category. 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 (requires login) and FDA Grant Funding Agencies (requires login) are also tracked in Scopus.

  1. Preparation and antibacterial performance of bacterial nanocellulose sachet containing Zataria multiflora essential oil loaded halloysite nanotubes on Escherichia coli O157:H7 in cheese

    • LWT

    • This study aimed to develop antimicrobial sachets by encapsulating Zataria multiflora essential oil (ZMEO) within halloysite nanotubes (HNTs) at different mass ratios (3:1, 2:1, and 1:1) and incorporating them into bacterial nanocellulose (BNC) films at two concentrations (10 % and 20 %) for cheese applications.

  2. Comparison of plasma-activated water and free chlorine in disinfecting Escherichia coli O157:H7- and Salmonella Typhimurium-inoculated blueberry, cherry tomato, fresh-cut lettuce, and baby spinach

    • LWT

    • The concentration of reactive oxygen and nitrogen species (RONS) in plasma-activated water (PAW) can be increased by increasing the input power, discharge voltage, and discharge time under a constant discharge frequency. However, knowledge regarding RONS concentration prepared under different discharge frequencies is lacking. This study investigated how decreasing the discharge frequency affects the chemical and physical properties of PAW.

  3. Isolation and characterization of a novel Salmonella bacteriophage JNwz02 capable of lysing Escherichia coli O157:H7 and its antibacterial application in foods

    • LWT

    • The topic of bacteriophage as an alternative to antibiotics to control pathogenic bacteria has attracted attention. Here, a novel virulent Salmonella bacteriophage JNwz02 capable of cross-infecting E. coli O157:H7 was isolated and characterized. The complete genome of JNwz02 was composed of 114390 bp double-stranded DNA molecules encoding 164 open reading frames (ORFs) with a G + C content of 40.22%.

  4. Accurate detection of Escherichia coli O157:H7 and Salmonella enterica serovar typhimurium based on the combination of next-generation sequencing and droplet digital PCR

    • LWT

    • Shiga-toxin producing Escherichia coli O157:H7 and Salmonella enterica serovar Typhimurium are important foodborne pathogens which are threatened to human health seriously.

  5. Molecular cloning, expression and characterization of a bacteriophage JN01 endolysin and its antibacterial activity against E. coli O157:H7

    • LWT

    • Endolysins encoded by bacteriophages are considered bacteriostatic agents for the prevention of pathogenic bacteria proliferations. In this study, a possible endolysin from bacteriophage JN01, namely LysJN01, belonging to the lysozyme-like superfamily, was cloned, expressed and characterized. Meanwhile, the bactericidal activity of recombinant LysJN01 (rLysJN01) against E. coli O157:H7 was evaluated in Tris-HCl buffer and on lettuce.

  6. Growth evaluation of Escherichia coli O157:H7, Salmonella typhimurium, and Listeria monocytogenes in fresh fruit and vegetable juices via predictive modeling

    • LWT

    • Fresh juices are often exposed to microbial contamination due to their minimal processing, which can lead to foodborne disease.

  7. Insight into the antibacterial activity of lauric arginate against Escherichia coli O157:H7: Membrane disruption and oxidative stress

    • LWT

    • Lauric arginate (LAE), an amino acid-based cationic surfactant, has recently attracted great attentions for applications in food preservation due to its antimicrobial properties. This work aimed to unravel the possible antibacterial mechanisms of LAE against Escherichia coli O157:H7. After exposure to LAE at 50 μg/mL for 10 min, the microbial load decreased by 6.25-log units.

  8. Adaptation of O157:H7 and non-O157 Escherichia coli strains in orange juice and subsequent resistance to UV-C radiation

    • LWT

    • This study assessed the acid-adaptation of pathogenic and non-pathogenic strains of Escherichia coli in orange juice and the microbial resistance to the subsequent UV-C radiation treatment. Nine Shiga toxin-producing E. coli (STEC) and one strain of a non-pathogenic surrogate E. coli were used in this study. Each E.
