Monitoring West Virginia Wastewater For Norovirus: A Test Case For Tracking Foodborne Illness Outbreaks In Rural Communities Using Wastewater, Haley M. Phillippi

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foodborne illnesses are a global public health challenge. Foodborne illnesses, like norovirus, often have a large disease and societal burden. Norovirus is a single-stranded, positive-sense RNA virus, with 10 identified genogroups (GI-GX). Genogroups GI and GII are responsible for nearly all human cases of acute gastroenteritis worldwide. In the United States, HuNoV is not notifiable case-by-case. Instead, outbreaks are reported to national surveillance systems when two or more cases are epidemiologically linked. Most norovirus outbreaks occur during Winter to early Spring, however, certain individuals may still shed and transmit the virus without being detected or reported. Wastewater monitoring is a …

ABSTRACT

Improving Food Safety Practices Among FSMA-Exempt Small-Scale Produce Growers: A Manuscript-Based Dissertation on Risk, Adoption, and Practical Barriers

Jesica Temple

Foodborne illness outbreaks associated with fresh produce continue to pose a public health risk in the United States. Although the Food Safety Modernization Act (FSMA) Produce Safety Rule (PSR) established science-based standards to prevent contamination, many small-scale farms are exempt from these requirements. Consequently, voluntary adoption of Good Agricultural Practices (GAP) varies widely across regions. Strategies to improve engagement among FSMA-exempt growers are key to advancing postharvest food safety and reducing contamination. This manuscript-based dissertation examined how knowledge, attitudes, …
