Efficacy Of Selected Powdered Floor Treatments And Turmeric Rhizome Powder Against Salmonella, E. Coli, And L. Monocytogenes On Polyurethane-Concrete Flooring Material Carriers, Robert Sidney Fuller Dec 2021

Efficacy Of Selected Powdered Floor Treatments And Turmeric Rhizome Powder Against Salmonella, E. Coli, And L. Monocytogenes On Polyurethane-Concrete Flooring Material Carriers, Robert Sidney Fuller

Graduate Theses and Dissertations

The flooring in a food processing environment can become contaminated with pathogenic bacteria in many ways including foot and equipment traffic, incoming materials, and drain backups. Turmeric (Curcuma longa L.) rhizome powder and seventeen other commercially available powdered floor treatments with a variety of active ingredients including quaternary ammonium compounds (QAC), sodium percarbonate and similar perhydrates (SPC), urea, and borax, were investigated for reducing the levels of pathogens on flooring thereby reducing the risk of cross-contamination from the floor to food contact surfaces. Some of the commercially available floor treatments were Environmental Protection Agency (EPA) registered antimicrobials while others were …


An Impedimetric Aptasensing System For The Rapid Detection Of Salmonella Typhimurium, America Sotero Dec 2020

An Impedimetric Aptasensing System For The Rapid Detection Of Salmonella Typhimurium, America Sotero

Graduate Theses and Dissertations

Salmonella Typhimurium is a foodborne pathogen associated with raw and undercooked eggs, poultry, beef, fruits, and vegetables. In the United States, Salmonella is responsible for approximately 1.2 million illnesses, 23,000 hospitalizations, and 450 deaths annually. For many years, conventional detection methods such as culture-dependent and PCR-based methods have been the “golden standards” for the detection of this pathogen due to their high sensitivity and reliability. However, they still have some disadvantages such as long enrichment steps and high costs that need to be overcome. The development of a rapid and reliable method for the detection of S. Typhimurium is needed …
