Harmful Algal Blooms: Risks For Food In Utah, Jose Brandao, Sarah Erwin, Stephanie Vaughn, Clare Entwistle Jul 2026

Harmful Algal Blooms: Risks For Food In Utah, Jose Brandao, Sarah Erwin, Stephanie Vaughn, Clare Entwistle

All Current Publications

Harmful algal blooms (HABs) are a problem because they can produce toxins that make water unsafe for people, animals, and the environment. In recent years, HABs have emerged as a growing concern in freshwater systems throughout Utah, including irrigation canals, reservoirs, and livestock ponds. HABs in freshwater are caused by cyanobacteria, also called blue-green algae. These microorganisms can release dangerous toxins that can harm swimmers, pets, and the food supply. Unlike foodborne pathogens, these toxins cannot be removed by boiling, cooking, or washing the food. Therefore, regular monitoring is essential to detect HABs early and reduce exposure risks. This fact …

From Insight To Impact: Segmenting Consumers By Their Regenerative Agriculture Priorities, Lourival Carmo Monaco Neto, Gustavo Stevanin De Souza, Owen Jerome Zakrzewski, Allan Wayne Gray Jul 2026

From Insight To Impact: Segmenting Consumers By Their Regenerative Agriculture Priorities, Lourival Carmo Monaco Neto, Gustavo Stevanin De Souza, Owen Jerome Zakrzewski, Allan Wayne Gray

Department of Agricultural Economics Faculty Publications

Regenerative agriculture is gaining traction in agrifood value chains, yet its definitional ambiguity and the heterogeneity of consumer priorities create strategic challenges for commercialization. Firms commonly assume a homogeneous ‘sustainable consumer’ motivated by environmental outcomes, but research on consumer food values suggests that economic attributes often outweigh environmental concerns when trade-offs are required. This study segments U.S. consumers based on how they prioritize seven core attributes of regenerative agriculture: soil health, biodiversity, greenhouse gas emissions, water use, food prices, crop yield, and farmer profitability. Using forced-ranking data from 1231 nationally representative U.S. consumers surveyed in August 2024, we apply a …

Food systems are a major contributor to exceeding planetary boundaries1,2,3 and poor quality diets are a key mortality risk globally4. Projected population and income growth could exacerbate these challenges5. In response, there are calls for transformation towards healthy and sustainable food systems6,7,8. However, the scale and distribution of the impacts of this transformation on agriculture are underexplored. Here we show that, by 2050, the transformation of food systems towards healthy diets (adoption of the EAT–Lancet reference diet), improved productivity and halving of food waste results in a fundamental restructuring of global agriculture, aspects of which break with historical trends.

Interactive Mechanism Of Food Packaging Design And Children's Health Consciousness, Yang Qian Jul 2026

Interactive Mechanism Of Food Packaging Design And Children's Health Consciousness, Yang Qian

Food and Machinery

Food packaging can establish an “entertainment–knowledge–action” interactive closed-loop mechanism for children, effectively guiding them to practice healthy behaviors, overcoming the low efficiency of conventional text- and image-based instruction, and continuously strengthening their health awareness. At present, interactive design for cultivating children’s health awareness through food packaging is constrained by superficial forms of interaction, insufficient integration of entertainment functions, fragmented system construction, and the absence of educational mechanisms in the implementation stage. The “entertainment–knowledge–action” closed-loop design can specifically address the limitations of traditional packaging, including fragmented interaction, superficial cognition, and weak behavioral guidance. Specifically, entertainment serves as the entry point by …

Consumer Judgment, Choice, And Meaning-Making In Food Packaging Design From The Perspective Of Consumption Alienation, Guo Jingzhi, Xu Ming Jul 2026

Consumer Judgment, Choice, And Meaning-Making In Food Packaging Design From The Perspective Of Consumption Alienation, Guo Jingzhi, Xu Ming

Food and Machinery

In the context of contemporary food consumption, food packaging has gradually shifted from a tool for product protection and information transmission to an important cognitive interface that influences consumer perception, judgment, and choice. Existing studies in this field mainly focus on functional optimization, behavioral guidance, and cultural expression, while insufficient attention has been paid to how packaging design affects consumer cognitive processes. This paper introduces the theoretical perspective of consumption alienation and employs literature analysis and comparative case studies to construct a three-layer analytical framework of “judgment–choice–meaning.” Furthermore, it proposes a regression-based analytical pathway centered on comprehensibility, choice support, and …
