Antibiotic Resistant Enterobacteriaceae In Milk Alternatives, Winnie Mukuna, Abdullah Ibn Mafiz, Bharat Pokharel, Aniume Tobenna, Agnes Kilonzo-Nthenge

Human Sciences Faculty Research

The consumption of non-dairy milk is on the rise due to health benefits. Although there is increasing inclination towards milk alternatives (MA), there is limited data on antibiotic resistant bacteria in these substitutes. The aim of this study was to investigate antimicrobial resistance of bacteria isolated from MA. A total of 138 extracts from almonds (n = 63), cashew nuts (n = 36), and soybeans (n = 39) were analyzed for Enterobacteriaceae. The identification of the bacteria was based on biochemical and PCR methods. Antibiotic sensitivity was determined by using the Kirby-Bauer disk diffusion technique. Overall, 31% (43 of 138) …

The Effects Of Various Carbon Sources And The Presence Of Vitamin B-12 On The Production Of 1,3-Propanediol By L. Reuteri., Kayden Stevenson

Fall Student Research Symposium 2021

Dairy product preservation has evolved over thousands of years and has been a major benefit to humanity by creating stable, nutrient-dense food sources. Today the lactic acid bacteria Lactobacillus reuteri is important in preserving fermented dairy products through the production of the compound reuterin. Reuterin (1,3-propanediol) demonstrates antibiotic properties that prevent the fermentation of dairy products by undesirable bacteria. The purpose of this study is to determine if L. reuteri can produce 1,3-propanediol from a variety of carbon sources. Bacterial strains were incubated in the presence of a carbon source with vitamin B-12 or without B-12 for seven days with …

Pilot Development Of A Critical Food Safety Message Visual Communication Tool For Farmers’ Market Vendors, Lilly W. Jan, Shannon M. Coleman, Anirudh Naig

Journal of Human Sciences and Extension

Farmers’ markets are popular sources of fresh and ready-to-eat foods for consumers in the United States. However, research indicates that food safety practices of vendors and their employees serve as a concern for customers. This pilot study focused on assessing a visual-based, minimal-text educational tool that was disseminated to farmers’ market vendors and employees (n = 27) in Iowa. The tool was evaluated using a post-intervention survey of vendors’ and employees’ knowledge of food safety practices and their attitudes towards the educational tool. The results did not show a statistically significant increase in attitude and knowledge scores of farmers’ market …

United States Food Law Update: Food Safely Planning, Attribute Labeling, And The Irradiation Debate, Bryan Endres

Journal of Food Law & Policy

This article summarizes significant changes and developments in food law throughout the second half of 2007. The previous edition of the Food Law Update noted the recent increase in imported food and the resulting stress placed on food safety agencies and customs officials. Detailed inspections of every food shipment entering the United States would quickly exhaust limited agency resources and cripple efficient international trade of food products. On the other hand, after several well-publicized food scares and the ongoing threat of international contamination, the public increasingly demands high levels of physical surveillance. As a part of this ongoing discussion, this …

Produce Exceptionalism: Examining The Leafy Greens Marketing Agreement And Its Ability To Improve Food Safety, Varun Shekhar

Journal of Food Law & Policy

Isolated food safety crises are not uncommon occurrences in the United States. Indeed, the history of public scares indicates a pattern of deficiencies in the safety of the American food supply. In the early 20th century, the public learned of the squalid conditions of meatpacking facilities through muckraking publications such as Upton Sinclair's The Jungle. In the 1980s, a 60 Minutes report documented research finding carcinogenic properties of a widespread pesticide, traces of which were commonly found in apple-based products. In the 1990s, widespread media reports of beef tainted with E. coli led to both product recalls unprecedented in scope …

United States Food Law Update: Moving Toward A More Balanced Food Regulatory Regime, A. Bryan Endres, Nicholas R. Johnson

Journal of Food Law & Policy

For decades, the federal government has played a significant role in promoting healthy eating. In the early 1900s, the United States Department of Agriculture (USDA) promoted a foundational diet of milk, proteins, fruits and vegetables, and grains. Most Americans are at least somewhat familiar, although perhaps confused, with the more nuanced healthy eating recommendations contained in the food pyramid - first employed in 1992. And virtually every American has experienced the federally supported school lunch program. In the first half of 2011, these two iconic programs underwent significant change as part of a stepped-up effort to improve the health of …

Toward A Constructive Engagement: Agricultural Biotechnology As A Public Health Incentive In Less-Developed Countries, Chidi Oguamanam

Journal of Food Law & Policy

Discourses on global public health crises, especially as they impact the less-developed world, focus mostly on the issue of access to life-saving drugs for needy populations. Also, they implicate the misalignment of global pharmaceutical research and development (R&D) agenda with the health needs of the poor. Equally attracting significant attention is the role of intellectual property in driving up the cost of drugs and exacerbating the drug access freeze to needy populations. More often, the conceptual strings of these discussions are woven around a complex interaction of themes, including those of globalization, the development narrative, and strategic changes in international …

The Market For Drug-Free Poultry: Why Robust Regulation Of Animal Raising Claims Is The Right Prescription To Combat Antibiotic Resistance, Dorinda L. Peacock

Journal of Food Law & Policy

Since their introduction in the mid-twentieth century, antibiotics have become a mainstay of poultry production for purposes ranging from growth promotion to disease treatment and control. Nevertheless, for almost as long, there have been concerns about the role that these agricultural uses play in the development of antibiotic resistant bacteria. The issue of antibiotic resistance in general is fast becoming a public health crisis and scrutiny of agriculture as a contributing cause continues. Nevertheless, to date, neither regulatory efforts to curb agricultural usage nor private sector actions in response to consumer demand and public-interest campaigns have led to significant changes …

Food Law & Policy: An Essay, Peter Barton Hutt

Journal of Food Law & Policy

Food has been the driving preoccupation of humans since the dawn of evolution. Exactly when food processing began and when the original hunter-gatherers settled down to develop agriculture-or even the question of which of these occurred first-remain issues of scholarly pursuit and debate. It is clear, however, that these events occurred millennia before the advent of recorded history; therefore, we must rely on largely adventitious discoveries of archeological artifacts to advance our developing knowledge of these events.

Evaluation Of Food Safety Practices At Louisiana Summer Feeding Sites And Food Safety Communication Via Social Media During Crises, Peyton E. Haynes

LSU Master's Theses

The United States Department of Agriculture’s Summer Food Service Program (SFSP) provided children under the age of 18 in low-income areas 145 million free meals in 2018 through summer feeding sites. Food safety issues arise for Louisiana feeding sites due to time-temperature controlled foods served, weather patterns in Louisiana, seasonal staff and short operation time, and lack of equipment. The purpose of this study was to assess food safety practices at Louisiana feeding sites through observational study with intention to compare food practices at institutional and noninstitutional sites. A rubric following USDA food safety guidelines based on categories: hot holding, …

Consumer Food Waste Behaviors In Relation To Open Date Label Misinterpretation, Daniel Hutchings, Elisabeth Seliga, Anya O'Meara, Anna Blank

Thinking Matters Symposium

In the United States, the legal framework for product date labeling is minimal and varies across states. Manufacturers have the discretion to use any date label that they deem appropriate, and this lack of uniformity leaves room for misinterpretation by both retailers and consumers. Previous studies have examined consumer misinterpretation of date labels and how this lack of knowledge correlates to food waste behaviors. This study was aimed at understanding how consumers apply their knowledge about date labels to make decisions about purchasing and discarding food. The research was conducted via an intercept survey outside of a grocery store to …

Narrow And Brittle Or Broad And Nimble? Comparing Adaptive Capacity In Simplifying And Diversifying Farming Systems, Margiana Petersen-Rockney, Patrick Baur, Aidee Guzman, S. Franz Bender, Adam Calo, Federico Castillo, Kathryn De Master, Antoinette Dumont, Kenzo Esquivel, Claire Kremen, James Lachance, Maria Mooshammer, Joanna Ory, Mindy J. Price, Yvonne Socolar, Paige Stanley, Alastair Iles, Timothy Bowles

Fisheries, Animal and Veterinary Sciences Faculty Publications

Humanity faces a triple threat of climate change, biodiversity loss, and global food insecurity. In response, increasing the general adaptive capacity of farming systems is essential. We identify two divergent strategies for building adaptive capacity. Simplifying processes seek to narrowly maximize production by shifting the basis of agricultural production toward centralized control of socially and ecologically homogenized systems. Diversifying processes cultivate social-ecological complexity in order to provide multiple ecosystem services, maintain management flexibility, and promote coordinated adaptation across levels. Through five primarily United States focused cases of distinct agricultural challenges—foodborne pathogens, drought, marginal lands, labor availability, and land access and …

United States Food Law Update, A. Bryan Endres

Journal of Food Law & Policy

Michael T. Roberts and Margie Alsbrook noted in the Journal's inaugural Food Law Update that "[t]he one constancy about food law in the United States is change, especially in a rapidly-developing food industry." This observation holds true today and also augurs a change in authorship of this section of the Journal. I hope to follow my colleagues' lead and provide timely and cogent updates of the federal (and occasionally state) statutes, regulations, and judicial decisions impacting food law and policy. It is both an honor and a duty, as food and its legal implications remain in many respects "the world's …

Heuristic And Hierarchical-Based Population Mining Of Salmonella Enterica Lineage I Pan-Genomes As A Platform To Enhance Food Safety, Joao Carlos Gomes-Neto, Natasha Pavlovikj, Carmen Cano, Baha Abdalhamid, Gabriel Asad Al-Ghalith, John Dustin Loy, Dan Knights, Peter C. Iwen, Byron D. Chaves, Andrew K. Benson

Department of Food Science and Technology: Faculty Publications

The recent incorporation of bacterial whole-genome sequencing (WGS) into Public Health laboratories has enhanced foodborne outbreak detection and source attribution. As a result, large volumes of publicly available datasets can be used to study the biology of foodborne pathogen populations at an unprecedented scale. To demonstrate the application of a heuristic and agnostic hierarchical population structure guided pan-genome enrichment analysis (PANGEA), we used populations of S. enterica lineage I to achieve two main objectives: (i) show how hierarchical population inquiry at different scales of resolution can enhance ecological and epidemiological inquiries; and (ii) identify population-specific inferable traits that could provide …

Evaluating Compliance With The Produce Safety Rule And Managing Mycotoxins, Yvette May Molajo

Walden Dissertations and Doctoral Studies

Foodborne diseases are the cause of many illnesses that occur from foods that contain mycotoxins. Mycotoxins are produced from fungi and are environmental and carcinogenic agents that contaminate agricultural foods during preharvest and postharvest conditions. While researchers have conducted many studies on mycotoxin occurrence and production, there is a significant gap in the current literature regarding which environmental factors could put farmers’ ability to remain in compliance with the Food Safety Modernization Act’s Produce Safety Rule at risk. Therefore, the purpose of this quantitative study was to investigate which environmental factors could put farmers’ ability to remain in compliance with …

Articles

: Salmonellosis is the second most reported gastrointestinal disorder in the EU resulting from the consumption of Salmonella-contaminated foods. Symptoms include gastroenteritis, abdominal cramps, bloody diarrhoea, fever, myalgia, headache, nausea and vomiting. In 2018, Salmonella accounted for more than half of the numbers of foodborne outbreak illnesses reported in the EU. Salmonella contamination is mostly associated with produce such as poultry, cattle and their feeds but other products such as dried foods, infant formula, fruit and vegetable products and pets have become important. Efforts aimed at controlling Salmonella are being made. For example, legislation and measures put in place reduced …

Proteome Analysis And Epitope Mapping In A Commercial Reduced-Gluten Wheat Product, Mitchell G. Nye-Wood, Angela Juhasz, Utpal Bos, Michelle L. Colgrave

Research outputs 2014 to 2021

Gluten related disorders, such as coeliac disease, wheat allergy and baker's asthma are triggered by proteins present in food products made from wheat and related cereal species. The only treatment of these medical illnesses is a strict gluten-free diet; however, gluten-free products that are currently available in the market can have lower nutritional quality and are more expensive than traditional gluten containing cereal products. These constraints have led to the development of gluten-free or gluten-reduced ingredients. In this vein, a non-GMO wheat flour that purports to contain “65% less allergenic gluten” was recently brought to market. The present study aims …
