The Persistence Of Human Norovirus Surrogate In Leafy Greens Production System, Wenjun Deng
The Persistence Of Human Norovirus Surrogate In Leafy Greens Production System, Wenjun Deng
Graduate Theses and Dissertations
Since mostly consumed raw, foodborne pathogen contamination of leafy greens has led to a large number of foodborne disease outbreaks and illnesses each year in the United States. Human noroviruses (hNoV) are the most common viral pathogen transmitted by leafy greens. In this dissertation, the persistence of the hNoV surrogate Tulane virus (TV) on pre-harvest lettuce and microgreens was investigated. Lettuces are the most studied leafy green model, while previous hNoV research has mainly focused on the post-harvest stage of production. Here, pre-harvest hydroponically grown lettuce were used to determine TV persistence on leafy greens. After inoculation on leaves at …
Risky Business: Millennials’ Protection Motivation Factors For Norovirus Outbreaks On College Campuses, Dylan Conrad Martinez
Risky Business: Millennials’ Protection Motivation Factors For Norovirus Outbreaks On College Campuses, Dylan Conrad Martinez
Graduate Theses and Dissertations
The risk and severity of hNoV transmission is obscurely recognized to foodservice millennial customers. Most commonly associated with cruise ships, consumers are not aware of its full potential to strike at other locations, especially college campuses. For the foodservice industry and the university community, it is imperative that a proactive method for increasing millennials’ motivation to practice mitigation methods emerges to reduce future hNoV outbreaks on college campuses. Research has shown that students can play a major role in the spread of hNoV on college campuses. Therefore, the purpose of these studies is to examine motivations for health protective behaviors …
Acanthamoeba Spp. As Reservoirs For Transmission Of Norovirus, Tun-Yun Hsueh
Acanthamoeba Spp. As Reservoirs For Transmission Of Norovirus, Tun-Yun Hsueh
Graduate Theses and Dissertations
Human noroviruses (HuNoV) are the most common cause of foodborne disease outbreaks in the United States and the most common food commodities implicated in HuNoV outbreaks are leafy greens; however, the vehicle of transmission and point of contamination are often unknown. Here, we hypothesize that common free-living amoebae (FLA) ubiquitous in the environment may act as reservoirs of HuNoV and facilitate the transmission of these pathogens to fresh produce. The objective of this research was to first evaluate the interaction/association between HuNoV surrogates and Acanthamoeba by incubating them together and analyzing virus titer associated with amoeba through an 8 day …
