Amyloid Fibrils: Potential Food Safety Implications, Michael Greger

Michael Greger, MD, FACLM

The demonstration of oral Amyloid-A (AA) fibril transmissibility has raised food safety questions about the consumption of amyloidotic viscera. In a presumed prion-like mechanism, amyloid fibrils have been shown to trigger and accelerate the development of AA amyloidosis in rodent models. The finding of amyloid fibrils in edible avian and mammalian food animal tissues, combined with the inability of cooking temperatures to eliminate their amyloidogenic potential, has led to concerns that products such as pâté de foie gras may activate a reactive systemic amyloidosis in susceptible consumers. Given the ability of amyloid fibrils to cross-seed the formation of chemically heterologous …

The Shifting Landscape Of Amish Agriculture: Balancing Tradition And Innovation In An Organic Farming Cooperative, Matthew J. Mariola, David L. Mcconnell

All Faculty Articles

In the context of the recent proliferation of alternative operations and marketing schemes across the agricultural landscape, this article examines an Amish organic farming cooperative in northeast Ohio. Contrary to popular perception, the large majority of Amish are not full-time farmers, and those who do farm typically use conventional, chemical-intensive methods. The adoption of certified organic among the Amish is a pragmatic decision that stems from concerns over the sociocultural effects of losing their agrarian heritage, but it also raises challenges that require a careful balance between market imperatives and cultural traditions. We investigate these challenges and the Amish response …

Animal Welfare And Food Safety Aspects Of Confining Broiler Chickens To Cages, Sara Shields, Michael Greger

Agribusiness Collection

In most areas of the world, broiler chickens are raised in floor systems, but cage confinement is becoming more common. The welfare of broiler chickens in cages is affected by movement restriction, poor bone strength due to lack of exercise, and prevention of key behavioral patterns such as dustbathing and ground scratching. Cages for broiler chickens also have a long history of causing skin and leg conditions that could further compromise welfare, but a lack of controlled studies makes it difficult to draw conclusions about newer cage designs. Cage environments are usually stocked at a higher density than open floor …

Public-Private Regime Interactions In Global Food Safety Governance, Ching-Fu Lin

Transnational Business Governance Interactions Working Papers

In response to an apparent decline in global food safety, numerous public and private regulatory initiatives have emerged to restore public confidence. This trend has been particularly marked by the growing influence of private regulators such as multinational food companies, supermarket chains and non-governmental organizations (NGOs), who employ private standards, certification protocols, third-party auditing, and transnational contracting practices. This paper explores how the structure and processes of private food safety governance interact with traditional public governance regimes, focusing on Global Good Agricultural Practices (GlobalGAP) as a primary example of the former. Due to the inefficiency and ineffectiveness of public regulation …

Time To Cry Over Spilled Milk: An Investigation Into China's Food Safety System, Rachel Baker

Honors Theses

China is plagued with food safety scandals ranging from contamination of dairy, to exploding watermelons in the countryside. This thesis explores the four main reasons that China has many food safety regulatory issues: the wide dispersion of farms in China, the fragmentation of the food safety regulatory system, weakness of local implementation, and the poor structure of commerce. Using the case studies of the dairy and pork industries this thesis examines these four proposed flaws and proposed solutions for improving food safety in China. Governmental flaws and mistakes are mostly responsible for these problems, but the current structure of government …

Intention To Comply With Food Safety Messages In A Crisis As A Function Of Message Source And Message Reliability, Karen June Freberg

Doctoral Dissertations

A key role of public relations is to manage crises, unexpected yet unpredictable events that cause emotional and physical harm (Coombs, 2007). Among the challenges in handling a crisis effectively is dealing with the various media in which information is presented. Because the use of social media in a crisis is a relatively new phenomenon, further understanding of the challenges and opportunities of these media is warranted. Part of meeting this challenge requires precise modeling of consumer responses to safety messages. To remedy gaps in our understanding of social media and food safety crisis communications, consumer intent to comply with …

An Hsi Report: Food Safety And Cage Egg Production, Humane Society International

HSI REPORTS

Governments have begun legislating against cage egg production and a growing number of major food retailers, restaurant chains, and foodservice providers worldwide are switching to cage-free eggs. Extensive scientific evidence strongly suggests this trend will improve food safety. All fifteen scientific studies published in the last five years comparing Salmonella contamination between caged and cage-free operations found that those confining hens in cages had higher rates of Salmonella, a leading cause of food poisoning worldwide. This has led prominent consumer advocacy organizations, such as the Center for Food Safety, to oppose the use of cages to confine egg-laying hens.

Awareness And The Perceived Effects Of The New Livestock And Meat Industries Act Of 2006: A Case Study Of Kgatleng And Kweneng Districts, Botswana, Patrick Malope, Elizabeth Ransom

Sociology and Anthropology Faculty Publications

The objective of this study was to determine whether butchery owners in rural Botswana are aware of the New Livestock and Meat Industries Act of 2006 and their perceptions as to how it will affect their businesses. The study further sought to determine whether the present slaughter facilities were compliant with the New Act. A structured questionnaire was administered to butcheries in selected villages of Kgatleng (n=9) and Kweneng (n=4) districts to get butchery owners’ views about the New Act and how it will affect their businesses. Data was analysed using frequencies.

The study found that the majority (77%) of …

Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li

Agribusiness Collection

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 …

Optimal Choice Of Voluntary Traceability As A Food Risk Management Tool, Dm Souza Monteiro,, Julie Caswell

Julie Caswell

Traceability systems are information tools implemented within and between firms in food chains to improve logistics and transparency or to reduce total food safety damage costs. Information about location and condition of products is critical when food safety incidents arise. This paper uses a principal-agent model to investigate the optimal choice of voluntary traceability in terms of precision of information on a given attribute at each link of a food chain. The results suggest that four scenarios may emerge for the supply chain depending on the costs of a system and whether or not the industry can internalize total food …

Food Fears: A National Survey On The Attitudes Of Australian Adults About The Safety And Quality Of Food, P. G. Williams, E. Stirling, N. Keynes

Peter Williams

A national telephone survey of a representative sample of 1200 Australian adults was conducted in March 2002 in order to identify the factors of greatest concern to consumers in relation to the safety and quality of food, to measure recent trends in views about hazards in the food supply, to explore beliefs about the safety of additives and to discover whether consumers use food labels to check for ingredients of concern. Forty five percent of Australians responded that they were more concerned about the safety and quality of food than they were five years previously, while only 5% were less …

Expanding The Focus Of Cost-Benefit Analysis For Food Safety: A Multi-Factorial Risk Prioritization Approach, Julie Caswell

Julie Caswell

A pressing need in the area of food safety is a tool for making overall, macro judgments about which risks should be given priority for management. Governments often seek to base this prioritization on public health impacts only to find that other considerations also influence the prioritization process. A multi-factorial approach formally recognizes that public health, market-level impacts, consumer risk preferences and acceptance, and the social sensitivity of particular risks all play a role in prioritization. It also provides decision makers with a variety of information outputs that allow risk prioritization to be considered along different dimensions. Macro-level prioritization of …

Consumer Demand For Quality: Major Determinant For Agricultural And Food Trade In The Future?, Julie Caswell

Julie Caswell

The impact of consumer demand for quality on the agricultural and food system is an increased emphasis on quality differentiation but not all in the direction of upgrading quality. The more elite market segments are thriving and reaching growing numbers of consumers but the basic price/quality markets remain strong. Most recent economic studies find that consumers are willing to pay for food safety and other quality attributes, and for information about them. The magnitude of the valuations varies by food product, attribute, country, and study design. This literature and a case study of genetically modified foods suggest that consumer demand …

Food Safety Innovation In The United States Evidence From The Meat Industry, Elise Golan, Tanya Roberts, Elisabete Salay, Julie Caswell, Michael Ollinger, Danna Moore

Julie Caswell

Recent industry innovations improving the safety of the Nation’s meat supply range from new pathogen tests, high-tech equipment, and supply chain management systems, to new surveillance networks. Despite these and other improvements, the market incentives that motivate private firms to invest in innovation seem to be fairly weak. Results from an ERS survey of U.S. meat and poultry slaughter and processing plants and two case studies of innovation in the U.S. beef industry reveal that the industry has developed a number of mechanisms to overcome that weakness and to stimulate investment in food safety innovation. Industry experience suggests that government …

The Genius Of The Nation Versus The Gene-Tech Of The Nation: Science, Identity, And Gmo Debates In Hungary, Krista Harper

Krista M. Harper

Introduction In the late 1990s, Hungarian politicians, environmentalists, and agricultural lobbyists weighed the pros and cons of allowing genetically modified (GM) food and seeds to enter the Hungarian market. Starting around 1994, a small group of Hungarian environmentalists began researching GM issues. Initially, they feared that as a post-socialist country seeking foreign investment, Hungary would become prey to multinational corporations seeking an ‘emerging market’ with a lax regulatory environment. The terms of the debate were reframed over time, notably following 1998, when a number of European Union member states banned the imports of GM foods and when Hungarian expatriate geneticist …

Food Safety Knowledge And Practices Of Food Recovery Agency Workers Before And After Food Safety Training, Sara Katherine Waggoner

LSU Master's Theses

Many food recovery agencies depend on donated food, and its safety is critical for the health of vulnerable populations. A food safety curriculum was developed for agency volunteers and paid staff of the Lower Mississippi Delta region. Examples of topics in the curriculum included: personal hygiene, food storage, transporting food safely, and HACCP. Food Safety Knowledge Pre- and Posttests (20 questions) were identical, and validity and reliability were established prior to use. Paired t-tests were performed to determine the effectiveness of the curriculum (n=190). A Food Safety Practices Survey (10 questions) demonstrating attitudes and behaviors regarding food safety practices in …

Public Perceptions Of Food Safety: Assessing The Risks Posed By Genetic Modification, Irradiation, Pesticides, Microbiological Contamination And High Fat/High Calorie Foods, Michael D. Mehta

The University of New Hampshire Law Review

[Excerpt] "In general, people in the developed world have access to a safe and varied supply of food. Instead of systemic hunger, many developed countries have problems with obesity and other kinds of eating disorders among their citizenry. It is within this context that some find public concerns about the safety of food both paradoxical and misplaced. Nevertheless, understanding how people perceive the risk associated with food is an important exercise in demonstrating accountability and in setting priorities for regulation. With the advent of technologies for producing genetically modified foods, and the development of fat blockers like Olestra, the public …

Using Informational Labeling To Influence The Market For Quality In Food Products, Julie Caswell

Julie Caswell

In the United States, the federal government is increasingly using requirements for informational labeling on food products to influence 1) consumers' knowledge and purchasing patterns and 2) manufacturers' product offerings and marketing practices. We discuss the economic rationale behind these regulations and issues related to judging their success or failure.
