Modeling For Thermal Resistance Of Non-O157 Shiga Toxin Producing Escherichia Coli In Ground Beef, Jagpinder S. Brar
Modeling For Thermal Resistance Of Non-O157 Shiga Toxin Producing Escherichia Coli In Ground Beef, Jagpinder S. Brar
Open Access Dissertations
Predictive models in microbiology are used for estimating the growth or survival of microorganism in a set of environmental conditions. A validated predictive model provides an alternative to extensive survival and shelf life studies. In this study, a predictive inactivation model for non-O157 shiga toxin producing Escherichia coli (STEC) in ground beef was developed. Six strains of non-O157 STEC; E. coli O26:H1, E. coli O45:H2, E. coli O103:H2, E. coli O111:H8, E. coli O121:H9, and E. coli O145: nonmotile, has similar pathogenicity as E. coli O157:H7 and can cause serious food borne illnesses. These pathogens are considered as an adulterant …
The Effects Of Using Cinnamon Leaf And Bark Essential Oils On Listeria Monocytogenes (L.M.), Salmonella Typhimurium (S.T.), In Model System, Strawberry Shake And Fresh Celery, And Sensory & Shelf Life Studies, Wafaa Brnawi
Graduate Theses and Dissertations
Essential oils derived from the bark and leaves of the cinnamon plant have long been used as natural preservatives and flavoring agents in different types of foods. In this study, we evaluated the antimicrobial effects of cinnamon essential oils (CEOs), obtained from cinnamon leaf or bark, against two foodborne pathogens i.e., Salmonella Typhimurium (S.T.) and Listeria monocytogenes (L.m.). Two different concentrations of microbial loading were used i.e.,109 and 104, cultured in nutrient media broth, strawberry shakes, and on celery sticks. Both CEOs of leaf and bark at 0.5% and 1% were found to completely inhibit S.T. and L.m., immediately after …
Development Of Bacteriophage Based Detection Technique For Food Safety And Environment Monitoring, Ziyuan Wang
Development Of Bacteriophage Based Detection Technique For Food Safety And Environment Monitoring, Ziyuan Wang
Doctoral Dissertations
Foodborne or waterborne pathogens which are responsible for numerous worldwide outbreaks of disease have caused serious health problems and enormous economic cost. Development of new bacterial detection technologies with high sensitivity and specificity is of great importance for food safety and public health. This has highlighted the significance of developing rapid and effective techniques for pathogen screening. Thus we aim to explore a bacteriophage mediated detection system for foodborne or waterborne bacteria monitoring. Bacteriophage as a novel recognition probe has been applied in various biosensor by immobilizing phage particles on solid sensor surface. They possess high specificity for targeted microorganism …

Farm-To-Fork Fresh Produce Food Safety: An Evaluation Of Perceptions, Knowledge, And Implementation Of Good Agriculture Practices In Kentucky, Daniel J. Sinkel
Farm-To-Fork Fresh Produce Food Safety: An Evaluation Of Perceptions, Knowledge, And Implementation Of Good Agriculture Practices In Kentucky, Daniel J. Sinkel
Masters Theses & Specialist Projects
Farmers’ markets have increasingly become a popular venue for purchase of fresh, locally-grown produce, with the number of farmers’ markets in Kentucky reaching an all-time high of 159 in 2016. Good Agriculture Practices (GAPs) is a program created by the USDA’s Agriculture Marketing Service to function as a food safety audit for small-scale fresh produce growers, such as those who sell fresh produce at local farmers’ markets. However, under the provisions of the Food Safety Modernization Act of 2011, small-scale farmers who sell an average of $25,000 in annual fresh produce sales across the span of three years are exempt …
Food Leftover Practices Among Consumers In Selected Countries In Europe, South And North America, Kadri Koppel, Federica Higa, Sandria Godwin, Nelson Gutierrez, Roman Shalimov, Paula Cardinal, Brizio Di Donfrancesco, Miriam Sosa, Angel A. Carbonell-Barrachina, Loreida Timberg, Edgar Chambers Iv

Foodborne illnesses may be related to many food production factors with home practices of consumers playing an important role in food safety. Consumer behavior for handling food leftovers has been studied, however little work on comparisons among countries has been published. The objective of this study was to investigate home food leftover practices of people from North American, South American, and European countries. Surveys were conducted with approximately 100 or more consumers in Argentina, Colombia, the United States, Estonia, Italy, Russia, and Spain. The participants responded to questions related to the length of time different types of food leftovers; such …
Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li
Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li
Peter J. Li, PhD
Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political …
Enzymatic Digestion Improved Bacteria Separation From Leafy Green Vegetables, Danhui Wang
Enzymatic Digestion Improved Bacteria Separation From Leafy Green Vegetables, Danhui Wang
Masters Theses
An effective and rapid method for the separation of bacteria from food matrix remains a bottleneck for rapid bacteria detection for food safety. Bacteria can strongly attach to the food surface or internalize within the matrix which makes their isolation extremely difficult. Traditional methods of separating bacteria from foods routinely involve stomaching, blending and shaking, however these methods may not be efficient at removing all the bacteria from complex matrices. Here, we investigate the benefits of using enzyme digestion followed by immunomagnetic separation to isolate Salmonella from spinach and lettuce. Enzymatic digestion using pectinase and cellulase was able to break …
