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. In Vitro Metabolism of Azaspiracids 1–3 with a Hepatopancreatic Fraction from Blue Mussels (Mytilus edulis)

    • Journal of Agricultural and Food Chemistry
    • Azaspiracids (AZAs) are a group of biotoxins produced by the marine dinoflagellates Azadinium and Amphidoma spp. that can accumulate in shellfish and cause food poisoning in humans. Of the 60 AZAs identified, levels of AZA1, AZA2, and AZA3 are regulated in shellfish as a food safety measure based on occurrence and toxicity. Information about the metabolism of AZAs in shellfish is limited. Therefore, a fraction of blue mussel hepatopancreas was made to study the metabolism of AZA1–3 in vitro.

  2. Conversion and Stability of New Metabolites of Paralytic Shellfish Toxins under Different Temperature and pH Conditions

    • Journal of Agricultural and Food Chemistry
    • A number of new C-11 hydroxyl metabolites (so-called M-toxins) of paralytic shellfish toxins (PSTs) have been discovered in contaminated shellfish, and trace amounts have also been detected in some strains of PST-producing microalgae.

  3. [ASAP] Magnetic Separation-Based Multiple SELEX for Effectively Selecting Aptamers against Saxitoxin, Domoic Acid, and Tetrodotoxin

    • Journal of Agricultural and Food Chemistry
    • In this study, a novel magnetic separation-based multiple systematic evolution of ligands by exponential enrichment (SELEX) was applied to select aptamers simultaneously against three kinds of marine biotoxins, including domoic acid (DA), saxitoxin (STX), and tetrodotoxin (TTX). Magnetic reduced graphene oxide (MRGO) was prepared to adsorb unbound ssDNAs and simplify the separation step.

  4. Proposed Biotransformation Pathways for New Metabolitesof Paralytic Shellfish Toxins Based on Field and Experimental MusselSamples

    • Journal of Agricultural and Food Chemistry
    • A seafood poisoning event occurred in Qinhuangdao, China, in April 2016. Subsequently, the causative mussels (Mytilus galloprovincialis) were harvested and analyzed to reveal a high concentration [∼10 758 μg of saxitoxin (STX) equiv kg–1] of paralytic shellfish toxins (PSTs), including gonyautoxin (GTX)1/4 and GTX2/3, as well as new metabolites 11-hydroxy-STX (M2), 11,11-dihydroxy-STX (M4), open-ring 11,11-dihydroxy-STX (M6), 11-hydroxy-neosaxitoxin (NEO) (M8), and 11,11-dihydroxy-NEO (M10).

  5. Development and Validation of a Lateral Flow Immunoassayfor the Rapid Screening of Okadaic Acid and All Dinophysis Toxinsfrom Shellfish Extracts

    • Journal of Agricultural and Food Chemistry
    • A single-step lateral flow immunoassay was developed and validated to detect okadaic acid (OA) and dinophysis toxins (DTXs), which cause diarrhetic shellfish poisoning. The performance characteristics of the test were investigated, in comparison to reference methods (liquid chromatography tandem mass spectrometry and/or bioassay), using both spiked and naturally contaminated shellfish.
