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. 85 Evaluation of a Saccharomyces cerevisiae fermentation product on performance, plasma metabolites, rumen parameters, and fecal pathogen shedding in feedlot steers

    • Journal of Animal Science

    • The objective of the experiment was to evaluate a commercial Saccharomyces cerevisiae fermentation product (SCFP; NaturSafe, Dimond V, Cedar Rapids, IA) on performance, plasma metabolites, rumen parameters, and fecal pathogen shedding in feedlot steers. Crossbred steers (n = 61; 271 ± 48.1 kg) were sourced from 3 different research units at Oklahoma State University and assigned to 1 of 3 experimental treatments in a randomized complete block design.

  2. 34 Assessing the Ability to Immunomodulate the Innate Immune System and Oxidative Status of Weaned Pigs Through a Prenatal Lipopolysaccharide Challenge

    • Journal of Animal Science

    • Gastrointestinal immunity and antioxidant defenses may be bolstered in young animals through prenatal immune system stimulation (PIS), but this is largely uninvestigated in swine. The objective of this experiment was to determine if a low dose of lipopolysaccharide (LPS) administered to late-gestating sows would alter the immune response and oxidative status of subsequent offspring.

  3. 218 Evaluation of a Direct-Fed Microbial Product (DIRECTä) on Fecal Shedding of Shiga Toxin-Producing Escherichia Coli in Finishing Cattle in a Commercial Feedlot

    • Journal of Animal Science

    • Shiga toxin-producing Escherichia coli (STEC), particularly seven serogroups O26, O45, O103, O111, O121, O145, and O157, are major food borne pathogens. Cattle are a major reservoir in which STEC colonize the hindgut and are shed in the feces. Most cattle shed the organisms at low concentrations and a small proportion, called super shedders, shed at high concentrations (≥ 104 per g).
