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.

  6. Metal Accumulation in American Sycamores in a Mining-Contaminated River in Southeastern Missouri

    • Sun, 04/03/2022 - 04:00
    • Water, Air, & Soil Pollution
    • The Big River, in the Old Lead Belt, southeast Missouri, experienced large-scale contamination of channel sediments and floodplain soils from over 200 years of lead mining pollution. Sediments of gravel bars downstream of mining in Big River are contaminated with Pb and Zn and have higher metal concentrations than upstream sites. Plants on these contaminated gravel bars are thus exposed to high metal concentrations and can accumulate metals.

    • Water, Air, & Soil Pollution
    • This paper describes a simple, quick, and solvent-free multi-residue method to determine 90 pesticides in groundwater samples from 30 different chemical groups. The extraction was carried out by solid-phase microextraction in direct immersion mode (DI-SPME) using a polydimethylsiloxane/divinylbenzene fiber (65 µm thickness) followed by GC–MS detection. The main parameters affecting the DI-SPME process were studied in detail: temperature, NaCl addition, stirring rate, and extraction time.

    • Water, Air, & Soil Pollution
    • Polycyclic aromatic hydrocarbons (PAHs) are harmful to the health of people and other organisms due to their high toxicity, difficult degradation, and wide distribution. At present, the removal of PAHs from the environment is still an urgent challenge. In this study, silica-coated magnetic nanoparticles were conjugated with DNA and then used to remove 1, 2-benzoanthracene (BaA) from aqueous solution due to the intercalation between BaA and DNA.

  25. Effect of Residual Pesticides in Recycled Nursery Runoff on Growth and Physiology of Six Ornamental Shrubs

    • Thu, 12/23/2021 - 02:00
    • Water, Air, & Soil Pollution
    • Nursery runoff may contain pesticide residues, which, if released off-site, could impair surrounding ecosystems. As a solution, nursery growers can retain runoff water on-site and recycle retained water to irrigate plants. However, concerns related to potential phytotoxicity caused by residual pesticides in recycled water can discourage growers from recycling water.
