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. Efficacy of slightly acidic electrolyzed water on inactivation of Cronobacter sakazakii and biofilm cell

    • Journal of Food Protection
    • The disinfection efficacy and mechanism of slightly acid electrolyzed water (SAEW) on Cronobacter sakazakii were investigated. SAEW solutions in three concentrations were carried on C. sakazakii which decreased in a range of 23%-55% in 2 minutes. The propidium iodide (PI) uptake and electronic microscopy (SEM) images indicated that SAEW treatment damaged cell integrity and changed membrane permeability with leaking nucleic acid (109.7%), intercellular protein (692.3%) and K + (53.6%).

  2. Synergistic Effects of Butyl Para-Hydroxybenzoate and Mild Heating on Foodborne Pathogenic Bacteria

    • Journal of Food Protection
    • ABSTRACT While high temperature heat treatments can efficiently reduce pathogen levels, they also affect the quality and nutritional profile of foods, as well as increase the cost of processing. The food additive butyl para-hydroxybenzoate (BPB) was investigated for its potential to synergistically enhance the thermal inactivation at mild heating temperatures (54 – 58 ºC).

  3. Prevalence of Cronobacter spp. and Salmonella in Milk Powder Manufacturing Facilities in the United States

    • Journal of Food Protection
    • The U.S. Food and Drug Administration (FDA) conducted a sampling assignment in 2014 to ascertain the prevalence of Cronobacter spp. and Salmonella in the processing environment of facilities manufacturing milk powder.Cronobacter was detected in the environment of 38 (69%) of 55 facilities.

  10. Reevaluation of a Suspected Cronobacter sakazakii Outbreak in Mexico

    • Journal of Food Protection
    • Jackson, Emily E. et al. In 2010, two infants became ill at a hospital in Mexico. Subsequently, a range of clinical, environmental, and powdered and rehydrated infant formula isolates were identified by using a combination of phenotyping and PCR probes. The strains were clustered according to pulsed-field gel electrophoresis. The causative agent was reported as Cronobacter sakazakii, with powdered infant formula (PIF) identified as the likely source of the infections.

  11. Development of Bioluminescent Cronobacter sakazakii ATCC 29544 in a Mouse Model

    • Journal of Food Protection
    • Wang, Xiwen et al. Cronobacter sakazakii is an emerging pathogen that causes severe and life-threatening conditions including meningitis, bacteremia, and necrotizing enterocolitis. An animal model study for extrapolation of C. sakazakii infection can provide a better understanding of pathogenesis. However, methods for real-time monitoring of the course of C. sakazakii infection in living animals have been lacking. We developed a bioluminescent C.

  12. Comparison of Desiccation Tolerance among Listeria monocytogenes, Escherichia coli O157:H7, Salmonella enterica, and Cronobacter sakazakii in Powdered Infant Formula

    • Journal of Food Protection
    • Koseki, Shigenobu et al. Bacterial pathogens such as Listeria monocytogenes, Escherichia coli O157:H7, Salmonella enterica, and Cronobacter sakazakii have demonstrated long-term survival in/on dry or low–water activity (aw) foods. However, there have been few comparative studies on the desiccation tolerance among these bacterial pathogens separately in a same food matrix.
