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.

    • Food Control
    • Coix seed is a minor cereal that has been used as a functional food in the Chinese diet due to its high nutritional value and health effects. These claimed health benefits include antioxidation, anti-cancer, anti-inflammation and enhancing immunological activity. But coix seed is easily contaminated by various mycotoxin, of which aflatoxin B1 (AFB1) is one of major threat to human and animal health.

  10. Detoxifying aflatoxin contaminated peanuts by high concentration of H2O2 at moderate temperature and catalase inactivation

    • Fri, 07/08/2022 - 04:00
    • Food Control
    • H2O2 treatment fulfills the requirement of environmentally friendly and safety concerns since it can be easily removed or decomposed into water and oxygen. Even though the high efficiency in detoxifying aflatoxins (AF) in foods by H2O2 was reported by some studies, the information to utilize this reagent for practical application is very limited. This study aimed at investigating the effect of 30 g/hg H2O2 at 50 °C on catalase-inactivated peanuts.

    • Fri, 07/08/2022 - 04:00
    • Food Control
    • The zearalenone (ZEN) lactonase from Gliocladium roseum (ZENG), possessing high activity but poor thermostability, is insufficient to meet the requirements of the feed industry. In this study, two potential hotspots, S162 and S220 in ZENG, were obtained through molecular dynamic (MD) simulations. In the first round, two mutants including S162P and S220R with increased thermostability were screened.

  14. Comparison of QuEChERS and Liquid–Liquid extraction methods for the simultaneous analysis of pesticide residues using LC-MS/MS

    • Tue, 06/28/2022 - 10:00
    • Food Control
    • In 2004, the Food Code of Korea adopted a multi-class multi-residue pesticide analysis method, which employed liquid–liquid extraction (LLE) and solid-phase extraction for sample purification. After several modifications, the LLE stage was replaced by the QuEChERS method in October 2021. Thus, in the current study a comparison was carried out between the new QuEChERS method and the conventional LLE method for the simultaneous analysis of multiple pesticide residues.

    • In this study, we analyzed enterotoxin genes, biofilm formation, and resistance to sixteen antimicrobials and chlorine dioxide (ClO2) in Bacillus cereus group isolates (n = 76) from samples (leaves, seeds, water and nutrients, and soil) from microgreen primary producing farms. Most isolates possessed at least one enterotoxin gene, as well as resistance to β-lactam antimicrobials, and more than half of the isolates showed moderate to strong biofilm-forming ability.

  19. The impacts of biosecurity measures on Campylobacter contamination in broiler houses and slaughterhouses in the Netherlands: A simulation modelling approach

    • Thu, 06/02/2022 - 04:00
    • Food Control
    • Intestinal campylobacteriosis, caused by Campylobacter ingestion, is the most reported zoonosis in the EU; it is societally costly and can lead to more severe sequelae. To reduce Campylobacter infections, biosecurity measures at both farms and slaughterhouses are warranted. However, the potential improvements achieved by these interventions have not been quantified.

  20. Use of β-cyclodextrin and milk protein-coated activated charcoal for rapid detection of Listeria monocytogenes in leafy greens by PCR without pre-enrichment

    • Thu, 05/26/2022 - 04:00
    • Food Control
    • Listeriosis outbreaks caused by contaminated leafy greens leaf have increased in recent years, which can pose a serious threat to public health. Thus, a rapid, precise, and effective detection method is urgently needed. We reported a novel sample pre-treatment that utilizes β-cyclodextrin and milk protein-coated activated charcoal to remove PCR inhibitors in leafy green matrices and facilitate the recovery of L. monocytogenes, which can be coupled with PCR subsequently.

    • Food Control
    • Listeria monocytogenes is a foodborne pathogen for humans. It can be found in ready-to-eat (RTE) products and its presence represents one of the biggest food safety concerns. Most of the cases of cheese contamination reported by the Rapid Alert System for Food and Feed (RASFF) in the last 10 years did not involve Mozzarella di Bufala Campana (MBC) Protected Designation of Origin (PDO) cheese.
