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. Novel subtypes and unexpected heterogeneity of hepatitis E viral strains in wild boar captured in a small area in Central Italy

    • Tue, 05/17/2022 - 04:00
    • Transboundary and Emerging Diseases
    • Transboundary and Emerging Diseases, Accepted Article. Wild boar is the main sylvatic reservoir of the genotype 3 of hepatitis E virus (HEV). The occurrence of HEV-3 human cases has been linked to the consumption of raw or undercooked pig and wild boar meat and liver. The zoonotic transmission of HEV-3 has been confirmed by sequencing identical or strictly related viral strains in humans, wild boar, and derived food.

    • Transboundary and Emerging Diseases
    • Transboundary and Emerging Diseases, Accepted Article. Zoonotic hepatitis E, mainly caused by swine hepatitis E virus (sHEV), is endemic in China, causing great economic disruption and public health threats. Although recombination is critical for the evolution of viruses, there is a limited assessment of its occurrence among sHEVs.

    • Transboundary and Emerging Diseases
    • Transboundary and Emerging Diseases, Volume 69, Issue 3, Page 943-957, May 2022. Toxoplasmosis is one of the most frequent food-borne infections in humans caused by an obligate intracellular protozoan parasite, Toxoplasma gondii. Rodents, as intermediate and reservoir hosts, play key role in the epidemiology of toxoplasmosis; because they are the main source of infection for the Felidae family members and establish the parasite life cycle. Hence, the infectious isolates of T.

    • Transboundary and Emerging Diseases, Volume 69, Issue 2, Page 286-296, March 2022. Hepatitis E is a significant liver disease caused by infection with hepatitis E virus (HEV). The risk factors for hepatitis E in developed countries include blood transfusion and ingestion of undercooked meat or meat products derived from HEV-infected animals. Since 2000, there has been increased human hepatitis E incidence reported in Singapore.

    • Transboundary and Emerging Diseases, Volume 69, Issue 2, Page 195-203, March 2022. In humans, co-infection of hepatitis B and C viruses (HBV, HCV) is common and aggravates disease outcome. Infection-mediated disease aggravation is poorly understood, partly due to lack of suitable animal models. Carnivores are understudied for hepatitis virus homologues. We investigated Mexican carnivores (ringtails, Bassariscus astutus) for HBV and HCV homologues.

    • Transboundary and Emerging Diseases
    • Transboundary and Emerging Diseases, Accepted Article. Campylobacter infection is an important cause of genital failure in ruminants in developed countries. Although historically Campylobacter fetus subspecies fetus has been the main cause of abortion in sheep, C. jejuni is also increasingly associated with sheep abortions. However, limited information is known on Campylobacter-associated abortions in China.
