Costs Of Improving Food Safety In The Meat Sector, 2016 Iowa State University
Costs Of Improving Food Safety In The Meat Sector, Helen H. Jensen, Laurian J. Unnevehr, Miguel I. Gomez
Recently enacted food safety regulations require processors to meet product standards for microbial contamination in meat products. An analysis of the cost-effectiveness of several technological interventions for microbial control in beef and pork processing shows that marginal improvements in food safety can be obtained, but at increasing costs. The additional food safety intervention costs represent about 1% of total processing costs for beef and pork. Some interventions and combinations are more cost-effective than others.
Discounting Spotted Apples: Investigating Consumers' Willingness To Accept Cosmetic Damage In An Organic Product, 2016 University of Minnesota - Twin Cities
Discounting Spotted Apples: Investigating Consumers' Willingness To Accept Cosmetic Damage In An Organic Product, Chengyan Yue, Frode Alfnes, Helen H. Jensen
The appearance of organic produce is often less than perfect because of limited methods of avoiding plant diseases. We combine hypothetical and real auction mechanisms to investigate how cosmetic damage affects Consumers' willingness to pay for apples. We find that 75% of the participants are willing to pay more for organic than for conventional apples given identical appearance. However, at the first sight of any imperfection in the appearance of the organic apples, this segment is significantly reduced. Furthermore, the cosmetic damage has a larger impact on the willingness to pay for organic apples than for conventional apples.
Assessing Food Security In Ethiopia With Usda Ers’S New Food Security Modeling Approach, 2016 United States Department of Agriculture
Assessing Food Security In Ethiopia With Usda Ers’S New Food Security Modeling Approach, Karen Thome, Birgit Meade, Stacey Rosen, John C. Beghin
Purpose: We analyze several dimensions of food security in Ethiopia, taking into account projected population growth, economic growth, and price information to estimate future food consumption by income decile. The analysis looks at the potential impact of large consumer price increases on food security metrics. Methodology: We use USDA ERS’s new modeling framework for its annual International Food Security Assessment. The modeling approach captures economic behavior by making food demand systematically responsive to income and price changes—a demand specification wellgrounded in microeconomic foundations. The projected change in food consumption can be apportioned to population growth, income growth, and ...
More Than Just Food: The Diverse Effects Of Food Assistance Programs, 2016 Iowa State University
More Than Just Food: The Diverse Effects Of Food Assistance Programs, Helen H. Jensen, Parke E. Wilde
For decades, from the 1940s to the 1970s, the goal of U.S. food and nutrition assistance programs seemed clear: to make sure low-income Americans could afford enough food. By pursuing this goal, the programs would protect program participants from hunger and also support demand for farm products. Today, about one in five Americans receives benefits from at least one of the U.S. Department of Agriculture’s (USDA) food programs. The major programs include the Supplemental Nutrition Assistance Program (SNAP), Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), school meals programs—lunch and breakfast, and the Child ...
Consumer Issues And Demand, 2016 Iowa State University
Consumer Issues And Demand, Helen H. Jensen
Consumers worldwide are driving changes in animal agriculture. Rising consumer income, changing demographics and lifestyles, and shifting preferences due to new information about the links between diet and health all contribute to new demands for foods. At the same time, technological changes in production, processing and distribution, structural change and growth in large-scale retailing, and expansion of trade worldwide have contributed to a rapidly changing market for food products. Changes in demand for meat and other animal products reflect these developments.
Mexico's Changing Pork Industry: The Forces Of Domestic And International Market Demand, 2016 Iowa State University
Mexico's Changing Pork Industry: The Forces Of Domestic And International Market Demand, S. Patricia Batres-Marquez, Roxanne L. Clemens, Helen H. Jensen
Once dominated by traditional and small-scale production systems with little regulation, Mexico's pork industry now includes modern, vertically integrated production systems and federal inspection of packing and processing plants. Recent structural changes have resulted in three distinct segments within the production and processing sectors as the industry works to adjust to international and domestic demand for better product quality, stricter sanitary practices, and increased supplies yet continue to meet the needs of low-income consumers. As the structural changes continue, the industry faces several challenges that will affect its ability to become both internationally and domestically competitive. To meet these ...
Challenges For China’S Agricultural Exports: Compliance With Sanitary And Phytosanitary Measures, 2016 Iowa State University
Challenges For China’S Agricultural Exports: Compliance With Sanitary And Phytosanitary Measures, Fengxia Dong, Helen H. Jensen
In the food safety arena, a clear role for government is to adopt sanitary and phytosanitary (SPS) measures to protect human, animal, and plant life or health. Relative to developing countries, developed countries tend to adopt more stringent food safety standards and regulations with a broader scope and to rely increasingly on certification and traceability. The additional costs of compliance for meeting international SPS requirements are higher for firms operating in developing countries because they must take additional steps to meet international food safety regulations and standards. Therefore, their comparative advantage, achieved through lower production costs, will tend to be ...
Strategies To Improve The Dietary Quality Of Supplemental Nutrition Assistance Program (Snap) Beneficiaries: An Assessment Of Stakeholder Opinions, Susan J. Blumenthal, Elena E. Hoffnagle, Cindy W. Leung, Hayley Lofink, Helen H. Jensen, Susan B. Foerster, Lilian Wy Cheung, Marion Nestle, Walter C. Willett
Objective: To examine the opinions of stakeholders on strategies to improve dietary quality of Supplemental Nutrition Assistance Program (SNAP) participants. Design: Participants answered a thirty-eight-item web-based survey assessing opinions and perceptions of SNAP and programme policy changes. Setting: USA. Subjects: Survey of 522 individuals with stakeholder interest in SNAP, conducted in October through December 2011. Results: The top three barriers to improving dietary quality identified were: (i) unhealthy foods marketed in low-income communities; (ii) the high cost of healthy foods; and (iii) lifestyle challenges faced by low-income individuals. Many respondents (70 %) also disagreed that current SNAP benefit levels were adequate ...
Us And German Consumer Preferences For Ground Beef Packaged Under A Modified Atmosphere – Different Regulations, Different Behaviour?, Carola Grebitus, Helen H. Jensen, Jutta Roosen
New technologies in food processing can provide advantages to consumers and producers but often the technologies are applied in different, country-specific regulatory climates. Modified atmosphere packaging extends the shelf life of fresh meat and, with the inclusion of carbon monoxide, stabilizes colour. These packaging technologies can be used in the US and Europe, although a modified atmosphere package that includes carbon monoxide is allowed only in the US. This study applies choice experiments to analyse preferences of US and German consumers towards the meat attributes enhanced by the packaging. Results show that longer shelf life is preferred in the US ...

This article charts the progress of CenUSA Bioenergy, a USDA-NIFA-AFRI coordinated agricultural project focused on the North Central region of the US. CenUSA’s vision is to develop a regional system for producing fuels and other products from perennial grass crops grown on marginally productive land or land that is otherwise unsuitable for annual cropping. This article focuses on contributions CenUSA has made to nine primary systems needed to make this vision a reality: feedstock improvement; feedstock production on marginal land; feedstock logistics; modeling system performance; feedstock conversion into biofuels and other products; marketing; health and safety; education, and outreach ...
Designing For Food Security: Portability And The Expansion Of User Freedoms Through The Corepds In Chhattisgarh, India, Prashant Rajan, Shweta Chopra, A. K. Somasekhar, Chad M. Laux
Food insecurity is a complex global problem, with approximately one in eight humans struggling with insufficient ac-cess to adequate nutrition. India accounts for the largest share of the world’s food-insecure population despite more than four decades of subsidized food production, distribution, and consumption. We report on the public distribu-tion of food through the COREPDS (centralized online real-time public distribution system), an ICT intervention in the public distribution system of Chhattisgarh, India. COREPDS is a theoretically driven ICT intervention that empowers households in Chhattisgarh by offering them the freedom to choose when, where, and how they wish to exercise their ...
Consumer Demand For Cholesterol-Lowering Enhanced Margarine Products, 2016 Iowa State University
Consumer Demand For Cholesterol-Lowering Enhanced Margarine Products, Sonya K. Huffman, Helen H. Jensen, Abebayehu Tegene
The development and introduction of nutritionally enhanced margarines in the mid-1990s offered the opportunity to improve public health through the use of a cholesterol-lowering food product. Product approval in the USA followed that in Europe. The public approval and market acceptance of the nutritionally enhanced product illustrate the challenges faced by offering improved health attributes through food product innovation. Although the product Benecol received public endorsement and was relatively quickly accepted by Finnish consumers, public acceptance has been slower in the USA. Our study traces consumer response to the introduction of nutritionally enhanced margarine products in the US market. Household ...

To Label Or Not To Label, That Is The Question, 2016 Iowa State University
To Label Or Not To Label, That Is The Question, Giancarlo Moschini
Genetically modified organisms (GMOs) have been welcomed by US agriculture and by a number of other countries (notably Canada and Argentina). Transgenic crops were virtually unkn own before 1996 but have experienced breathtaking adoption rates. For example, in 1999 more than 50 percent of the soybean crop grown in the United States is genetically modified (at least -+0 percent of U.S. com and 50 per cent of U.S. cotton are also transgenic). For the next crop yea r, it is estimated that 100 percent of the soybeans grown in Argentina will be herbicide resistant. But GMOs have struck ...

Reducing Antibiotic Use In Animal Production Systems, 2016 Iowa State University
Reducing Antibiotic Use In Animal Production Systems, Helen H. Jensen
Antimicrobial drugs are commonly used for animals raised in food production for treatment, control, and prevention of disease as well as growth promotion or increased feed efficiency in many production systems. A recent report from the USDA Economic Research Service (Sneeringer et al. 2015) indicates that the share of hogs, broilers, and beef cattle that have been raised without the use of antibiotics has increased, although a significant share of animals do receive antibiotics for growth promotion or disease prevention (e.g., 59 percent of finishing hogs in 2009 and 52 percent of broilers in 2011). Furthermore, many producers reported ...
The Rise Of Obesity In Transition: Theory And Empirical Evidence From Russia, 2016 Iowa State University
The Rise Of Obesity In Transition: Theory And Empirical Evidence From Russia, Sonya K. Huffman, Marian Rizov
Since the early 1990s series of political and economic reforms have been implemented in transition economies. As a result, the population experienced dramatic changes in lifestyle and a significant decline in life expectancy. The adverse effects of transition were most severe in the Former Soviet Union. Several studies examine the reasons for the mortality crisis in Russia and other former Soviet republics (Brainerd and Cutler, 2005; Shkolnikov et al., 2004). Greater alcohol consumption and increased stress from the transition to a market economy had dramatically affected the lifestyle and diet of the population, and led to higher mortality in Russia ...
The Rise Of Obesity In Transition Economies: Theory And Evidence From The Russian Longitudinal Monitoring Survey, 2016 Iowa State University
The Rise Of Obesity In Transition Economies: Theory And Evidence From The Russian Longitudinal Monitoring Survey, Sonya K. Huffman, Marian Rizov
This study integrates theoretical and empirical models to facilitate understanding of human obesity and the factors contributing to rising obesity in Russia during the transition from a planned to a market economy. Recent individual level data from the Russian Longitudinal Monitoring Survey for 1994 and 2004 show that diet/caloric intake, smoking, gender and education are important determinants of obesity in Russia. Empirical results strongly support our model for production of BMI and demand for inputs in the BMI production function. The analysis provides information on the link between dietary patterns and other factors of obesity in Russia which is ...
Consumer Choices And Welfare Gains From New, Healthy Products: A Virtual Prices Approach, 2016 Iowa State University
Consumer Choices And Welfare Gains From New, Healthy Products: A Virtual Prices Approach, Sonya K. Huffman, Ariun Ishdorj, Helen H. Jensen
This paper models consumer food choices with respect to different margarine and spread brands that include a new healthy brand. The results show that the older and smaller size households with higher income and higher education are more likely to purchase the healthy brand. An Almost Ideal Demand System for six brands was estimated and the coefficients were used to calculate price and brand expenditure elasticities in order to examine the responsiveness of the consumers to economic variables.
