Food and Agriculture Features and Impacts

Despite control efforts, Salmonella remains a major cause of foodborne outbreaks in the U.S. resulting in an annual estimated loss of around $4 billion. Anup Johnny and his team are working to discover effective methods to control multidrug-resistant Salmonella to improve the safety of poultry products.

Roger Ruan and his team are developing intense pulsed light (IPL) technology to reduce harmful bacteria and other microorganisms in dry or powdered foods. For the project, they have designed and fabricated a small lab scale system for testing the IPL process in terms of microbial inactivation and physical, chemical and sensory changes under different conditions.

A three-year study looks at the specific fatty acids profile in milk produced from cows fed a 100 percent forage-based diet to cows under both conventional and organic management. 

UMN researchers participated in a multi-year and multistate experiment on soil functional zone management (SFZM) in corn and soybean systems that examined both ridge-till and chisel-plow tillage systems both with and without a rye cover crop and compared plant growth, yield, nutrient status, soil attributes and greenhouse gas emissions.

New wheat varieties and sharing of best practices are helping MN farmers grow more wheat on less acreage. 

A new multivariable model looks at how geographical factors may be a significant factor to help predict the risk of a PRRS outbreak.

Soybean aphid (Aphis glycines) has been wreaking havoc on Midwest soybeans since it was first discovered in 2000. While careful management practices have helped keep yields up, the possibility of aphids having resistance to insecticides remains a key concern. 

Minnesota has seen rapid growth in its wine industry, particularly in the past decade. To continue this growth, vineyard owners are in constant need of new and better products and varieties to boost their industry and keep wine lovers interested.

An analysis of the economic impact of the northern grape industry uncovers continued growth and opportunities.

Insect pollinators provide essential services to growers of US fruits, vegetables, nuts and seeds and honeybees are their star performer accounting for over two-thirds of the agricultural output attributed to insect pollination. Research projects and extension programs are uncovering new information to help Minnesotans protect this essential insect.
