ONGOING RESEARCH

Update on Tuesday, September 1, 2015

This research will explore the concept of "internalized" Salmonella contamination in ground poultry components and the role of lymphoid tissue as harborage sites for this pathogen.

Update on Tuesday, September 1, 2015

This research intends to develop a reliable and quantitative method that can measure the impact of interventions designed to reduce the carriage of Salmonella in peripheral lymph nodes of cattle.

Funded in part by The Beef Checkoff

Update on Tuesday, September 1, 2015

The project is designed to provide a better understanding and address the lack of scientifically-supported tools available to the industry to define lethal cooking processes and establish validated regulatory compliance for different ready-to-eat meat products.  

Update on Tuesday, April 1, 2014

This project will evaluate the effectiveness of partial dehairing from various solutions and mechanical scraping as a hide-on carcass intervention to reduce Salmonella and E. coli.

Update on Tuesday, April 1, 2014

This project will demonstrate the sensitivity and specificity of droplet digital PCR as an enumeration assay for Salmonella enterica in pure culture and in mixed microflora cultures as well as inoculated ground beef of different fat contents

Update on Tuesday, April 1, 2014

This project will determine if food animal isolates of the top ten Salmonella serovars associated with human infections are resistant to chemical antimicrobial interventions used in processing. The resistance elements associated with human infections will be compared to those found in animals to determine if some chemical interventions used during processing may be selecting for the serovars that most often cause human infections

COMPLETED RESEARCH

Final report submitted on Tuesday, March 1, 2016

This study will investigate the impact of compositional, physical, and intrinsic factors on pathogen lethality and the relationship between relative humidity and wet bulb control to determine if wet bulb could be utilized as a more effective and suitable lethality tool. This project builds on previous AMIF-funded research.

Final report submitted on Wednesday, October 1, 2014

Research determined the relationship between Salmonella contamination levels in bone marrow, neck skin, and spleen of turkey carcasses to that in ground product.

Final report submitted on Sunday, June 1, 2014

This white paper defined multi-drug resistance as related to different bacterial pathogens; discusses sources of multi-drug resistance and how resistance genes are transmitted among different strains and different species of bacteria; identifies multi-drug resistant bacteria associated with different foods and food production animals; evaluates efficacy of interventions to prevent development of multidrug resistance and to prevent contamination of foods with multidrug resistant pathogens; and recommends risk mitigation strategies in a preventive food safety process management system.

Final report submitted on Thursday, August 1, 2013

The study developed methodology to allow the Rti-PCR reaction to detect low numbers (5 cells/g) of Salmonella in ground beef of 7, 15, and 27% fat.
