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.

  1. Spectinomycin, gentamicin, and routine disc diffusion testing: An alternative for the treatment and monitoring of multidrug-resistant Neisseria gonorrhoeae?

    • Sat, 05/07/2022 - 04:00
    • Journal of Microbiological Methods
    • Introduction

      Neisseria gonorrhoeae is a major concern of public health due to its extraordinary capacity to develop and acquire resistance to different antimicrobials used to treat gonorrhoea. Limited treatment options and uncontrolled transmission have raised the need to assess the antimicrobial susceptibility profile of the isolates and to establish affordable alternatives for laboratory diagnosis.

  2. Multiple sgRNAs for one-step inactivation of the duplicated acetyl-coenzyme A carboxylase 2 (ACC2) genes in Brassica napus

    • Wed, 05/04/2022 - 05:00
    • Plant Physiology
    • Efficient plastid transformation in Arabidopsis (Arabidopsis thaliana) requires genetic lines that are hypersensitive to spectinomycin due to the absence of a chloroplast acetyl-coenzyme A carboxylase (ACCase) encoded in the acetyl-coenzyme A carboxylase 2 (ACC2) nuclear gene. To obtain plastid transformation-competent oilseed rape (Brassica napus), we inactivated all nuclear encoded, chloroplast targeted ACCase copies using CRISPR–Cas9.

  3. Dioxin Disrupts Thyroid Hormone and Glucocorticoid Induction of klf9, a Master Regulator of Frog Metamorphosis

    • Wed, 04/27/2022 - 04:00
    • Toxicological Sciences
    • Frog metamorphosis, the development of an air-breathing froglet from an aquatic tadpole, is controlled by thyroid hormone (TH) and glucocorticoids (GC). Metamorphosis is susceptible to disruption by 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), an aryl hydrocarbon receptor (AHR) agonist. Krüppel-like factor 9 (klf9), an immediate early gene in the endocrine-controlled cascade of expression changes governing metamorphosis, can be synergistically induced by both hormones.

  4. Effects of 1,3,7-tribromodibenzo-p-dioxin, a natural dioxin on chicken embryos: Comparison with effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin

    • Wed, 04/27/2022 - 04:00
    • Ecotoxicology and Environmental Safety
    • Several naturally occurring dioxins, including 1,3,7-tribromodibenzo-p-dioxin (1,3,7-TriBDD), synthesized by red algae, have been detected in the marine environment. As 1,3,7-TriBDD is accumulated in mussels and fish, predators, such as marine birds, are exposed to this congener, similar to anthropogenic dioxins (including 2,3,7,8-tetrachlorodibenzo-p-dioxin TCDD).

  5. Occurrence and fate of Adsorbable Organic Halogens (AOX) in two WWTPs from Romania

    • Wed, 04/20/2022 - 04:00
    • Archives of Environmental Contamination and Toxicology
    • Absorbable organic halogens (AOX) are a global parameter which refers to a group of chemical compounds that contain one or more chlorine, bromine or iodine atoms in their molecule and can easily adsorb on activated carbon. The global concern related to the occurrence of the AOX compounds in the environment is due to their toxic and mutagenic effects on aquatic organisms and their potential role as inhibitors of microorganism growth, even at AOX low concentrations.

    • Sat, 04/02/2022 - 04:00
    • Ecotoxicology and Environmental Safety
    • Exposure to environmental pollutants, including dioxin-like pollutants, can cause numerous health issues. A common exposure route to pollutants is through contaminated foods, and thus the gastrointestinal system and gut microbiota are often exposed to high amounts of pollutants. Multiple studies have focused on the imbalance in intestinal microbiota composition caused by dioxin-like pollutants.
