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. Quantitative differential analysis of norovirus outbreak samples using RT‐ddPCR

    • Letters in Applied Microbiology

    • Letters in Applied Microbiology, Accepted Article. Noroviruses cause acute gastroenteritis with symptoms of diarrhea and vomiting, and their high infectivity allows outbreaks to readily occur. Quickly identifying and isolating potential contaminants is an effective method to prevent the spread of outbreaks.

  2. Continuous detection of norovirus and astrovirus in wastewater in a coastal city of China in 2014–2016

    • Letters in Applied Microbiology

    • Letters in Applied Microbiology, Accepted Article. Norovirus (NoV) and human astrovirus (HAstV) are important causative agents of acute gastroenteritis in children and adults. They comprised of multiple genotypes and attention should be paid to genotype changes or emergence of new genetic variants. To study the prevalence and diversity of NoV GI, GII and HAstV circulating in eastern China, we conducted a three-year environmental surveillance in a coastal city of Yantai.

  3. Efficacy of alcohol‐based hand sanitizers against human norovirus using RNase‐RT‐qPCR with validation by human intestinal enteroid replication

    • Letters in Applied Microbiology

    • Successful human norovirus (HuNoV) cultivation in stem cell‐derived human intestinal enteroids (HIE) was recently reported. The purpose of this study was to evaluate the anti‐HuNoV efficacy of two alcohol‐based commercial hand sanitizers and 60% ethanol by suspension assay using RNase‐RT‐qPCR, with subsequent validation of efficacy by HuNoV cultivation using the HIE model.

  4. Virus inactivation in groundwater in postglacial lava field in arctic climate

    • Letters in Applied Microbiology

    • Outbreaks of viral gastroenteritis are often connected to contaminated drinking water. The assessment of the water quality relies on cultivation of indicator bacteria, and little is known of the fate of viruses in groundwater, especially in arctic regions. In Iceland, the groundwater temperature is between 3°C and 6°C. The aim of this study was to determine virus inactivation at low temperature in a groundwater microcosm and in a borehole in a postglacial lava field.

  5. Tungsten carbide nanoparticles show a broad spectrum virucidal activity against enveloped and nonenveloped model viruses using a guideline‐standardized in vitro test

    • Letters in Applied Microbiology

    • Significance and Impact of the Study: The present study investigates the virucidal activity of tungsten carbide nanoparticles using the quantitative suspension test in accordance with the European norm EN 14476+A1 and the German DVV/RKI guidelines. Due to highly standardized assay conditions, results of this test are considered very reliable for evaluation of the virucidal activity of disinfectants.

  9. The impact of anthropogenic pressure on the virological quality of water from the Tiber river, Italy

    • Letters in Applied Microbiology

    • Abstract

      The objective of the present study was to assess the occurrence of major waterborne enteric viruses (enterovirus, norovirus, adenovirus, rotavirus, hepatitis A and E virus) along the Tiber River in Italy, in areas affected by different kinds of anthropogenic pressure (agricultural, urban, industrial, and pristine). Moreover, in light of the recent abundant detection of human bocavirus in urban wastewater samples in Italy, the occurrence of this virus was also assessed.

  12. Transfer of Acanthamoeba spp. to Fresh Produce from Water and Environmental Surfaces

    • Letters in Applied Microbiology

    • Human noroviruses (HuNoV) are the primary cause of foodborne disease outbreaks in the United States. The most frequent commodities implicated in HuNoV outbreaks are leafy greens where contamination may occur during production and harvesting practices. With respect to transmission of HuNoV to fresh produce, one hypothesis is that free-living amoebae that are ubiquitous in the environment (soil, sediments, water) can serve as vehicles of contamination through interaction with viruses.
