Food and Machinery
[Objective] To establish a rapid detection method for viable Salmonella based on specific phage infection and recombinase polymerase amplification (RPA) in response to the key challenge that traditional molecular biological detection methods have difficulty in conveniently distinguishing between viable and non-viable foodborne pathogens. [Methods] Taking advantage of the characteristic that O-1 phage only proliferates in viable bacteria, the phage is added to the enriched sample. After further incubation, total DNA is extracted. Fluorescent RPA is used to determine whether the phage has significantly proliferated, so as to judge the presence of viable Salmonella in the original sample. [Results] After optimization, …

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 …

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 …
