Validation of Gold Nanoparticle DNA-based Biosensors for the Detection of Non-PCR Amplified Bacterial Food Borne Pathogens in Food Matrices

Principal Investigator: 
Sylvia Vetrone
Since the intentional distribution of Bacillus anthracis spores through the US postal system in 2001, the prospect of bioterrorism in food, water, and agriculture has identified critical needs in prevention, protection, and mitigation for homeland security. Towards that end, we recently...

Food Product Tracing Technology Capabilities and Interoperability

Principal Investigator: 
Tejas Bhatt; Jennifer (Previous PI) McEntire
Despite the best efforts of food safety professionals, contaminated food continues to enter the food supply. It is imperative that contaminated food be removed from the supply chain as quickly as possible to protect public health and stabilize markets. In addition to findings highlighted in the...

Validation of Agent Inactivation and Isolation from Food Systems

Principal Investigator: 
Alvin Lee
Validation of a process needed to eliminate a microbiological or chemical hazard in food can be difficult. Processing technologies that have shown efficacy in eliminating a hazard under laboratory conditions, usually under well controlled parameters, may not be effective against the threat agent...

Application of Surface Enhanced Raman Spectroscopy in Detection of Chemical and Biological Terror Agents in Food Matrices II

Principal Investigator: 
Theodore Labuza
The objectives of this continuing project are to apply, improve, and validate developed SERS immunoassays to detect real ricin and anthrax spores in milk, Both antibody and aptamer will be used as capturers. The DNA aptamer is expected to give more distinct SERS patterns compared with protein...

Validation and optimization of biologically modified electrically-active magnetic nanoparticles (nano-BEAMs) for direct capture and concentration of bioterrorism agents in various food matrices

Principal Investigator: 
Evangelyn Alocilja
The existing project focuses on the synthesis and novel application of biologically modified electrically-active magnetic nanoparticles (nano-BEAMs) for sample acquisition and pre-analytical processing to render representative samples of food products ready for rapid agent detection in multiple...

Social Media Constraints and Opportunities Case Studies and Industry White Paper Project

Principal Investigator: 
Michael Palenchar
Social media is the number one use on the Internet, offering an opportunity to take advantage of the power of social media to reduce the consequences of food-related events, while gaining a better understanding of the psychological and social aspects of stakeholders’ relationships to such events...

Modeling Sampling Strategies for Detecting Intentional Contamination of Imported Food Systems

Principal Investigator: 
Randall Singer
Significant quantities of fresh and frozen food are imported into the U.S. each year. In particular, fruits, vegetables and seafood are imported from countries around the world, and once these products arrive into the U.S., they are broadly distributed and either consumed directly or used as...

Chemical Inactivation of Protein Toxins on Food-Contact Surfaces

Principal Investigator: 
Jack Cappozzo
Ricin and abrin are potent plant toxins found in seeds of the castor bean plant and rosary pea plant, respectively. Both toxins have potential for being used as biological weapons since they are relatively easy to isolate and purify and can be disseminated as food contaminants. In the case of a...

Impact of Select Rodenticides on the Coagulation Properties of Milk Proteins

Principal Investigator: 
Salam Ibrahim
During enzymatic coagulation of milk, three separate but overlapping processes occur: (1) enzymatic hydrolysis, (2) aggregation, and (3) gelation. These processes must occur successfully in order to produce a desirable milk coagulum for cheese production. Key to the success of these processes is...
