Rework Practices in the Dairy Industry and Their Potential Contribution to Microbial Spoilage

Creator:: Rush, Casey E.
Abstract:: Rework is a common practice in the dairy industry as a way for processors to minimize waste while recovering costs for dairy products that are unsaleable. The regulations available for reworking fluid dairy products only outline product eligibility requirements with a focus on repasteurization of the products containing rework as...

Mitigation of Microbiological Water Quality by Last Irrigation-to-Harvest Intervals

Creator:: Emch, Alexander W.
Abstract:: Foodborne outbreaks involving fresh produce have been on the rise since the late 1990's. Pathogens such as Salmonella spp. and Escherichia coli are prevalent in agricultural environments and commonly travel between farms via irrigation water. The Food Safety Modernization Act (FSMA) has placed an increased emphasis on microbiological standards of...

The Examination of Escherichia coli Contamination via Agricultural Water Applications and Survival During Pre-Harvest Field Curing of Dry Bulb Onions

Creator:: Racine, Jason R.
Abstract:: 2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...

An Exploration of Cheese Safety Parameters and Aging as Mitigation Strategy for Foodborne Pathogens in Cheese

Creator:: Riesgaard, Brandon
Abstract:: Pasteurization is an effective method of reducing risks associated with foodborne pathogens in raw milk. Cheese made from raw milk has a higher potential to harbor harmful bacterial pathogens. However, some cheesemakers prefer to use unpasteurized milk to preserve the natural microflora present in the raw milk and to prevent...

Influence of Processing Parameters on the Inactivation of Salmonella spp. During the Cooking Step of Jerky Production Using a Commercial-Scale Dehydrator

Creator:: Minarsich, Joey
Abstract:: United States Department of Agriculture-Food Safety and Inspection Service (USDA-FSIS) guidelines for beef jerky processing support producers' ability to satisfy the performance standard requirements for achieving a 5-log reduction in Salmonella and E. coli O157:H7. The first compliance guide for jerky processors was created in response to several Salmonella outbreaks...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

Important Considerations for Food Process Validations : Strain Selection, Contamination Level, and Relevant Treatment Conditions

Creator:: Pearson, Eva
Abstract:: Reports of foodborne outbreaks have increased in the last decade, posing a public health risk to consumers. In an attempt to mitigate this risk, the newly established Food Safety and Modernization Act (FSMA) takes a preventive rather than reactive approach to food safety. Under FSMA, producers are required to validate...

Validation of Baking to Reduce Coliform Counts and Salmonella in Cookie Dough

Creator:: Wilson, Julia M.
Abstract:: This study aimed to determine the efficacy of baking to reduce bacterial populations (an unknown contaminant or Salmonella) in cookie dough. Baking conditions (time and temperature parameters) were selected based on conditions commonly used in industry. The first study (Chapter 2), “Baking as Validation for Control of Coliform Counts in...

Investigating Potential Environmental Sources for Coliforms in Cheddar Cheese Production

Creator:: Selover, Brandon J.
Abstract:: The production of Cheddar cheese is a complex process with multiple potential sources of undesirable bacteria, including those that have negative impacts on product quality (spoilage organisms) and those that are used to evaluate sanitary conditions in the production environment (indicator organisms). The dairy industry commonly uses coliform bacteria as...

Further Optimization of Controlled Depuration for Eliminating Vibrio parahaemolyticus from Raw Oysters for Safe Consumption

Creator:: Ming, Ziwen
Abstract:: Vibrio parahaemolyticus infections in the United Stated have been linked to consumption of raw shellfish, particularly oysters, with symptoms of headache, abdominal pain, nausea, diarrhea, vomiting. Depuration, as a post-harvest process, has a long history of being applied in shellfish industry to reduce sewage bacteria. In order to reduce the...
