The Use Of Inorganic And Organic Acids As Short Duration Antimicrobial Dips On Mitigating Pathogens Present On Commercial Chicken During Peri-Harvest, Dana Kristen Dittoe

Graduate Theses and Dissertations

With poultry being the most consumed meat in the United States, poultry processors must provide consumers with safe, wholesome products. As a consequence, poultry processors are faced with the challenge of reducing the presence of foodborne pathogens such as Salmonella spp. and Campylobacter jejuni among raw poultry products. Though multi-hurdle approaches using antimicrobials are placed throughout processing to reduce these pathogens, Salmonella and C. jejuni still persist among raw poultry. Thus, it was the objective of the current dissertation to investigate various antimicrobials, organic and inorganic acids, as short duration dips and sprays as means to reduce common pathogens (Salmonella, …

Research Tools And Their Uses For Determining The Thermal Inactivation Kinetics Of Salmonella In Low-Moisture Foods, Soon Kiat Lau

Department of Food Science and Technology: Dissertations, Theses, and Student Research

The reputation of low-moisture foods as safe foods has been crumbling over the past decade due to repeated involvement in foodborne illness outbreaks. Although various pasteurization technologies exist, a majority are thermal processes and have not been well-characterized for pasteurizing low-moisture foods. In addition, the nature of a low-moisture food matrix introduces various experimental complications that are not encountered in high-moisture foods. In this dissertation, the development, building instructions, and characterization of various open source tools for studying the inactivation kinetics of microorganisms in low-moisture foods are described. The first tool is the TDT Sandwich, a dry heating device for …

Regulatory Disclosure Policies And Potential Induced Changes In Behavior: An Outcome Evaluation Of Santa Clara County’S Enhanced Food Safety Program Elements, Christian Cruz

Master's Projects

Despite countless advances in food microbiology and public health regulations, foodborne illness continues to be a major strain on public health outcomes and a costly economic burden. In the United States, many agencies are responsible for ensuring the quality of food, both domestically produced and imported. States and localities are delegated the responsibility of identifying and ensuring sound practices in the latter stages of the food production process, namely the retail distribution of food products to consumers.

Regulatory policies across the nation have only recently incorporated the evidenced-based principles of hazard risk management (Law, 2003). Still, food-related acute gastrointestinal illnesses …

Microbial Safety, Shelf Life Stability, Quality Preservation, And Consumer Acceptance Of Vacuum-Infused, Irradiated Chicken Breast Meat Treated With Natural Plant Extracts And Organic Acids, Kenneth Franklin Over

Graduate Theses and Dissertations

Contamination of poultry products with food borne pathogens is a consistently recurring problem in the United States and the world. Recalls associated with chicken contamination are responsible for considerable economic losses to the poultry industry. Many decontamination steps are currently in place to reduce the likelihood of contaminated products reaching the consumer, but despite these safeguards, contamination events are still uncomfortably frequent. Irradiation is a safe and effective means of ensuring the safety of both ready-to-cook and ready-to-eat poultry but is not utilized in the United States. This is due, in part, to certain irradiation dose-dependent quality characteristic defects associated …

Seasonal Prevalence Of Shiga-Toxin Producing Escherichia Coli On Beef Cattle Farms In Eastern Arkansas, Tiffani Elizabeth Breckenridge

Student Theses and Dissertations

Sixty-five million U.S. citizens become ill from foodborne bacteria annually; 73,000 of these bacterial illnesses are caused by Shiga-toxin producing Escherichia coli (STEC) O157. Cattle are a reservoir of STEC; therefore, STEC contamination of beef is a significant food safety concern in the U.S. On-farm STEC control measures may reduce the incidence of contamination in processing facilities. The objective of this study was to determine prevalence of O157 and non-O157 STEC on beef cattle farms in eastern Arkansas, and to possibly identify farm management and/or environmental risk factors associated with STEC prevalence in cattle. Rectal swab samples (10 cows per …
