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.
