Standards as Barriers Versus Standards as Catalysts: Assessing the Impact of HACCP Implementation on U.S. Seafood Imports

The United States mandated a Hazard Analysis Critical Control Points (HACCP) food safety standard for seafood in 1997. Panel model results for the period 1990 to 2004 suggest that HACCP introduction had a negative and significant impact on overall seafood imports from the top 33 suppliers. While the effect for developed countries was positive, the negative HACCP effect for developing countries supports the view of “standards-as-barriers” versus ”standards-as-catalysts.” When the effect is analyzed at an individual country level a different perspective emerges. Regardless of development status, leading seafood exporters generally gained sales volume with the U.S., while most other smaller trading partners faced losses or stagnant sales.

A Multifactorial Risk Prioritization Framework for Foodborne Pathogens

We develop a prioritization framework for foodborne risks that considers public health impact as well as three other factors (market impact, consumer risk acceptance and perception, and social sensitivity). Canadian case studies are presented for six pathogen-food combinations: Campylobacter spp. in chicken; Salmonella spp. in chicken and spinach; Escherichia coli O157 in spinach and beef; and Listeria monocytogenes in ready-to-eat meats. Public health impact is measured by disability-adjusted life years and the cost of illness. Market impact is quantified by the economic importance of the domestic market. Likert-type scales are used to capture consumer perception and acceptance of risk and social sensitivity to impacts on vulnerable consumer groups and industries. Risk ranking is facilitated through the development of a knowledge database presented in the format of info cards and the use of multicriteria decision analysis (MCDA) to aggregate the four factors. Three scenarios representing different stakeholders illustrate the use of MCDA to arrive at rankings of pathogen-food combinations that reflect different criteria weights. The framework provides a flexible instrument to support policymakers in complex risk prioritization decision making when different stakeholder groups are involved and when multiple pathogen-food combinations are compared.

The Benefits and Costs of Proliferation of Geographical Labeling for Developing Countries

Food product attributes related to geographical origins are a topical issue in global food trade. The provision of geographical labelling may occur through geographical indications under the mandated trade rules of the TRIPS Agreement, trademarks, or country-of-origin labelling. The overall effect of the expansion of geographical labelling on developing countries depends on a complex mix of market opportunities that may yield substantial benefits as well as implementation costs. Increasingly, the analysis of this overall effect will need to evaluate the joint impacts of different forms of geographical labelling on the market position of developing countries.

A Multi-Factorial Risk Prioritization Framework for Food-Borne Pathogens

To lower the incidence of human food-borne disease, experts and stakeholders have urged the development of a science- and risk-based management system in which food-borne hazards are analyzed and prioritized. A literature review shows that most approaches to risk prioritization developed to date are based on measures of health outcomes and do not systematically account for other factors that may be important to decision making. The Multi-Factorial Risk Prioritization Framework developed here considers four factors that may be important to risk managers: public health, consumer risk perceptions and acceptance, market-level impacts, and social sensitivity. The framework is based on the systematic organization and analysis of data on these multiple factors. The basic building block of the information structure is a three-dimensional cube based on pathogen-food-factor relationships. Each cell of the cube has an information card associated with it and data from the cube can be aggregated along different dimensions. The framework is operationalized in three stages, with each stage adding another dimension to decision-making capacity. The first stage is the information cards themselves that provide systematic information that is not pre-processed or aggregated across factors. The second stage maps the information on the various information cards into cobweb diagrams that create a graphical profile of, for example, a food-pathogen combination with respect to each of the four risk prioritization factors. The third stage is formal multi-criteria decision analysis in which decision makers place explicit values on different criteria in order to develop risk priorities. The process outlined above produces a ‘List A’ of priority food-pathogen combinations according to some aggregate of the four risk prioritization factors. This list is further vetted to produce ‘List B’, which brings in feasibility analysis by ranking those combinations where practical actions that have a significant impact are feasible. Food-pathogen combinations where not enough is known to identify any or few feasible interventions are included in ‘List C’. ‘List C’ highlights areas with significant uncertainty where further research may be needed to enhance the precision of the risk prioritization process. The separation of feasibility and uncertainty issues through the use of ‘Lists A, B, and C’ allows risk managers to focus separately on distinct dimensions of the overall prioritization. The Multi-Factorial Risk Prioritization Framework provides a flexible instrument that compares and contrasts risks along four dimensions. Use of the framework is an iterative process. It can be used to establish priorities across pathogens for a particular food, across foods for a particular pathogen and/or across specific food-pathogen combinations. This report provides a comprehensive conceptual paper that forms the basis for a wider process of consultation and for case studies applying the framework.

Competition and Credibility of Private Third-Party Certification in International Food Supply

With globalization a number of international food standards and certification systems emerged in modern food supply chains. Third-party certifiers are critical institutions and play a pivotal role in quality assurance. This article investigates how the level of competition among accredited certifiers changes with increasing number of quality assurance schemes and new firms entering the market. Our goal is to understand how structural changes in the third-party certifiers (TPCs) market might impact its competitiveness. This is an issue of increasing significance that, to the best of our knowledge, has received little attention in the agribusiness literature.

The Effects of ITQ Management on Fishermen’s Welfare When the Processing Sector is Imperfectly Competitive

In this paper we use a general model of imperfect competition to predict welfare changes within an open-access fishery after it transitions to individual transferable quota (ITQ) management. Although related research has explored the effects of market power in the harvesting sector on ITQ performance, none has considered the implications of an imperfectly competitive processing sector. Addressing this question, we find that although fishermen should expect to gain from ITQs under perfect competition, they may suffer welfare losses if the processing sector is imperfectly competitive.

Communicating Diabetes Best Practices to Clients: A Preliminary Investigation of Educator Perspectives

Purpose. The majority of people with type 2 diabetes do not meet dietary and physical activity recommendations. It is not well understood how diabetes educators translate diet and physical guidelines for their clients and if diabetes educators have sufficient resources to promote healthy eating and physical activity. This research addressed these questions through exploratory qualitative interviews. Method. A total of 13 diabetes educators who work in Alberta, Canada, were interviewed. Results. The reasons for lack of client uptake of lifestyle recommendations were complex and interwoven. The strongest theme to emerge was the clients’ prior knowledge and skills affecting their ability to uptake knowledge. However, educators recognized that clients are affected by social, environmental, cultural, and personal factors. Conclusions. Health system and societal issues cause a cascade effect resulting in difficulties for both educators and clients. To achieve appropriate treatment of type 2 diabetes, changes need to occur at a health systems level.

Markets segmented by regional-origin labelling with quality control

It is the objective of this paper to provide a methodological framework for the analysis of regional marketing programs which inlclude regional-origin labelling as well as quality assurance and control. Such programs are increasingly being introduced in Europe and other parts of the world as a means against quality uncertainty in globalized markets. An equilibrim – displacement model is developed for a segmented market with differential qualities that can be utilized for a broad variety of marketing programs. It is applied to one selected European case, i.e. “Gepruefte Qualitaet – Bayern”. It is shown that the price impacts on high-quality and low-quality segments depend crucially on substitutive relationships between the markets and the advertising elasticities. Welfare implications for producers in a program depend strongly on advertising elasticities, too, but also on the costs of participation including quality control and on the co-financing mechanism between government and producers.

The international quest for an integrated approach to microbial food‐borne risk prioritization: where do we stand?

This paper provides a review and evaluation of different food‐risk prioritization and management frameworks that have been developed by governmental food‐safety authorities, regulatory agencies and non‐governmental institutions worldwide. It emphasizes the need for a new science‐ and risk‐based system approach to microbial risk prioritization. We find that most studies and projects argue for a systematic and multi‐disciplinary approach to risk prioritization but nevertheless lack it. Human and public health issues have constituted the core focus of food‐risk analysis in food‐borne risk prioritization studies, where the majority of studies use the concept of disease burden. Even though it is widely recognized that economic and market‐level impacts of microbial hazards and preventive interventions to reduce food‐borne risks are crucial to the performance of industries and markets, they are almost never accounted for in risk prioritization frameworks.

Diabetes, Diet-Health Behavior, and Obesity

High-quality diets play an important role in diabetes prevention. Appropriate dietary adherence can improve insulin sensitivity and glycemic control, and thus contribute to lifestyle improvement. However, previous research suggests that dietary adherence is arguably among the most difficult cornerstones of diabetes management. The objectives of this study are (1) to estimate whether and to what extent individuals diagnosed with diabetes show significant differences in diet quality [healthy eating index (HEI)] compared to healthy individuals, (2) to quantify whether and to what extent diabetics experience significantly higher outcomes of body mass index (BMI), and (3) to estimate whether and to what extent dietary supplementation impacts diabetes patient’s diet quality and/or BMI outcomes. We use data from the 2007–2008 U.S. National Health and Nutrition Examination Survey (NHANES). The NHANES is the primary, randomized, and nationally representative survey used to assess the health and nutritional status in the U.S. We apply propensity score matching (PSM) to account for selection bias and endogeneity between self-reported diet and health behavir (treatment) and BMI outcomes. We control for an individual’s BMI as to capture the impact of past dietary behavior in its impact on HEI. Matching results suggest that regular dietary supplement consumption is associated with significant lower BMI outcomes of almost 1 kg/m2. The close relationship between diabetes and obesity has been at the center of the diet-health policy debate across Canada and the U.S. Knowledge about this linkage may help to improve the understanding of the factors that impact dietary choices and their overall health outcomes, which may lead to a more efficient and effective promotion of dietary guidelines, healthy food choices, and targeted consumer health and lifestyle policies.
