Research Publications (Food Safety)

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. Inhibition of Bacterial Adhesion and Antibiofilm Activities of a Glycolipid Biosurfactant from Lactobacillus rhamnosus with Its Physicochemical and Functional Properties

    • Sat, 12/18/2021 - 00:00
    • Antibiotics
    • Biosurfactants derived from different microbes are an alternative to chemical surfactants, which have broad applications in food, oil, biodegradation, cosmetic, agriculture, pesticide and medicine/pharmaceutical industries. This is due to their environmentally friendly, biocompatible, biodegradable, effectiveness to work under various environmental conditions and non-toxic nature.

    • Journal of Agricultural and Food Chemistry
    • A multifunctional surface, subsurface and systemic therapeutic (MS3T) formulation comprised of two bactericides, both didecyldimethylammonium chloride (DDAC) and a zinc (Zn)-chelate, was developed as an alternative to copper pesticides for crop protection. Agricultural grade chemicals were used to prepare MS3T formulations.

  3. Characterization of Emerging Pathogens Carrying blaKPC-2 Gene in IncP-6 Plasmids Isolated From Urban Sewage in Argentina

    • Tue, 08/24/2021 - 16:00
    • Frontiers in Cellular and Infection Microbiology
    • Untreated wastewater is a reservoir for multidrug-resistant bacteria, but its role in the spread of antibiotic resistance in the human population remains poorly investigated. In this study, we isolated a KPC-2-producing ST2787 Klebsiella quasipneumoniae subsp. quasipneumoniae (WW14A), recovered from raw sewage at a wastewater treatment plant in Argentina in 2018 and determined its complete genome sequence. Strain WW14A was resistant to all β-lactams, ciprofloxacin and amikacin.

    • Fri, 05/07/2021 - 04:02
    • Journal of Food Protection
    • Edible insects are a novel food in most countries; their popularity is growing because of their high protein/low fat content, ease of cultivation, and small environmental impact. To our knowledge, this is the first report that addresses both microbiological and chemical hazards in edible insects. Samples were collected from retail stores or purchase through e-commerce. A total of 51 samples of dried whole insects or insect powders were tested for generic Escherichia coli ( E.

    • Journal of the Science of Food and Agriculture
    • ABSTRACT Background Fruit and vegetable consumption has increased among masses due to their tremendous health benefits. However, recent studies have shown that contaminated products may serve as a vehicle for foodborne pathogens and harmful chemicals. Therefore, fresh vegetables must be decontaminated before consumption to ensure food safety.

  9. Selection for Resistance to a Glyphosate-Containing Herbicide in Salmonella enterica Does Not Result in a Sustained Activation of the Tolerance Response or Increased Cross-Tolerance and Cross-Resistance to Clinically Important Antibiotics

    • Wed, 11/25/2020 - 10:01
    • Applied and Environmental Microbiology
    • Evolution of bacterial tolerance to antimicrobials precedes evolution of resistance and may result in cross-tolerance, cross-resistance, or collateral sensitivity to other antibiotics. Transient exposure of gut bacteria to glyphosate, the world’s most widely used herbicide, has been linked to the activation of the stress response and changes in susceptibility to antibiotics.

    • Fri, 09/11/2020 - 04:02
    • Journal of Agricultural and Food Chemistry
    • To reduce the use of conventional chemical pesticides, naturally occurring biopesticides such as bacteriophages have emerged as a promising solution, but effectiveness of these biopesticides can be limited because of their UV and desiccation instability. This study developed a biopolymer formulation to improve the phage stability, enhance the antimicrobial activity of phages, and prevent bacterial contaminations on a leaf surface in the presence of UV-A.

    • Journal of Food Processing and Preservation
    • Two medicinal plants, African Locust Bean (Parkia biglobosa) and Lonicera japonica, traditionally used in West Africa and China were investigated against four spoilage microorganisms: Bacillus subtilis, Cronobacter dublinensis, Pantoea agglomerans, and Bacillus sp., isolated from mulberry fruit. The aqueous extract of the P. biglobosa (ALB) was potent with average inhibitory zones against four spoilage microorganisms recorded as (Means ± SD) 6.5 to 19.5 mm as well as 6.5 to 15.5 mm for L.
