Infectivity of Norovirus in Shellfish Treated With High Hydrostatic Pressure Processing-Human Challenge Study (Shellfish)
Norwalk virus and related "Norwalk-like viruses" are the most common cause of outbreaks of stomach sickness (nausea, vomiting, diarrhea) in older children and adults in the United States. These viruses are sometimes found in drinking water, ice, shellfish and in other foods. They can be spread easily from contact with water, food, objects or hands that have even small amounts of feces from someone who was sick.
The purpose of this research study is to the effectiveness of high hydrostatic pressures processing (HPP) treatment on norovirus infected shellfish. Norwalk virus can survive in shellfish and still be able to cause sickness. HPP inactivates microorganisms living both on the surface and on the interior of the food. The goal of the study is to determine whether HPP treatment on oysters spiked with norovirus will reduce infection rates in people consuming raw infected oysters.
|Study Design:||Intervention Model: Single Group Assignment
Masking: Double Blind (Participant, Care Provider, Investigator)
Primary Purpose: Prevention
|Official Title:||Norwalk Virus Inactivation by High Hydrostatic Pressure Processing: A Comprehensive and Integrated Program for Research and Outreach|
- Infection with norovirus [ Time Frame: Throughout participation in study ]
|Study Start Date:||September 2007|
|Study Completion Date:||March 2010|
|Primary Completion Date:||October 2009 (Final data collection date for primary outcome measure)|
Experimental: Shellfish with Norovirus
We dosed shellfish with Norovirus and challenged human volunteers with Shellfish that had norovirus
Procedure: High Hydrostatic Pressure Processing
High Hydrostatic Pressure Processing is a technology, used in the food service industry, where foods are subjected to high pressure. These high pressures kill many pathogens without affecting the quality of the food.
Other Name: HPP
