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. Effect of electron beam irradiation on minas frescal cheese artificially contaminated with Shiga toxin-producing Escherichia coli O157:H7

    • International Dairy Journal

    • Minas frescal cheese (MFC) is a potential vehicle for Shiga toxin-producing Escherichia coli (STEC) O157:H7. The effect of electron beam irradiation on the control of STEC O157:H7 in artificially contaminated MFC (5 log cfu g-1) was evaluated. Samples were irradiated at doses of 1.0, 1.5, and 2.0 kGy and evaluated for 40 days at 4 °C. Shelf life extension and the stability of the lipid fraction of the cheeses were also evaluated.

  2. An esterase activity-based biosensor for rapid and sensitive detection of viable Escherichia coli O157:H7 in milk

    • International Dairy Journal

    • Escherichia coli O157:H7 is harmful to humans by producing toxins that cause thrombotic thrombocytopenic purpura and haemolytic uraemic syndrome. Real-time recombinase-aided amplification (rRAA) can generate real-time fluorescence signals to achieve sensitive detection of pathogens within 20 min but cannot distinguish dead bacteria from viable bacteria, leading to false-positive results.

  3. Behaviour of Escherichia coli O157:H7 in raw and mild pasteurised donkey milk treated with high pressure

    • International Dairy Journal

    • The survival of E. coli O157:H7 strain (NCTC 12900) was assessed in raw donkey milk, in mild pasteurised donkey milk (50 ° C for 30 min), in donkey milk processed by HP at 400 MPa at 3 °C for 60 s, and in donkey milk treated with a combination of the two technologies. The results showed that E. coli O157:H7 was able to survive in raw donkey milk for 15 days and in mild pasteurised donkey milk for 4 days.
