Modeling the Public Health System Response to a Terrorist Event

Principal Investigator: 
Don Schaffner
The objective of this project was to conduct simulation modeling of the public health system, specifically focusing on the detection of deliberate food contamination events by the public health system, and the response of that system to such events. The simulation model can be used to evaluate the...

Use of Plasma Technology to Decontaminate Surfaces and Air in Food Processing Environments

Principal Investigator: 
Amy Wong
The overall goal of the proposed research is to use plasma-aided technologies to disinfect surfaces and air in food processing environments that have been contaminated with Bacillus cereus spores, a surrogate for Bacillus anthracis. This proposal specifically addresses Aim D.1.2 "Test specific...

Extraction, Concentration, and Detection of Toxins in Solid Food Systems using Molecular Imprinted Polymer Films

Principal Investigator: 
Keith Warriner
An integrated system to extract, concentrate and detect Staphylococcus aureus exterotoxin B (SEB) has been developed. The main focus of the work was to deliver a robust, low cost system that could be automated to permit on-site toxin screening capabilities. Since biological affinity agents are...

Chemical stability of ricin under conditions that mimic pasteurization of beverages

Principal Investigator: 
Peter Varelis
Ricin and abrin are two plant-derived proteins that have been identified as potential bioterrorism agents because of their acute toxicities and the quantities that can be readily isolated from the seeds of two ubiquitous plants (Ricinus communis and Abrus pecatorius, respectively). Whilst several...

Evaluation of Methods for Decontamination of Food Processing Equipment and Facilities Deliberately Contaminated with Bacillus Spores

Principal Investigator: 
Martin Cole
To validate the effects of various cleaning and liquid/gaseous sanitizing protocols for decontamination of food processing equipment and facilities with spores of several potential surrogate Bacillus species including B. anthracis Sterne strains, with validation under controlled conditions using B...

Concentrating Bacterial Spores from Milk and Juices using Dielectrophoresis-Based Microfluidic Capture Systems

Principal Investigator: 
Suresh Pillai
A microscale prototype device that can be ultimately scaled up for concentrating bacterial spores from large volumes of milk and apple juice is developed. Dielectrophoresis (DEP) is utilized to concentrate Clostridium sporogenes as surrogates of Bacillus anthracis and Clostridium botulinum spores...

Public Health Investigation of Multistate Foodborne Outbreaks

Principal Investigator: 
Craig Hedberg
Purpose: These CIFOR multi-jurisdictional guidelines are intended to help improve communication and coordination between agencies investigating multi-jurisdictional outbreaks at all levels of governmental organization. The guidelines are proposed to help agencies identify multijurisdictional...


Principal Investigator: 
Craig Hedberg
FoodSHIELD ( is a Web-based platform designed to facilitate communication and coordination among the various food and agricultural sector laboratories and regulatory agencies. Two comprehensive databases are being developed to support FoodShield: Food&AgDIR, which...
