The present study systematically investigated the effects of warehouse and greenhouse aquaponic growing conditions on consumer acceptability of different basil cultivars. A total of 105 consumers rated their liking of three basil cultivars (Nufar, Genovese, and Eleonora), each grown in three conditions (aquaponically in a greenhouse, aquaponically in a warehouse, both with Cyprinus carpio, Koi fish, and grown in soilless medium). We used linear random effect models to investigate consumer preferences for attributes of basil plants grown in different environments by controlling for individual-specific random effects. Participants generally liked the soilless medium–grown and greenhouse aquaponically grown basil plants more than the warehouse aquaponically grown plants. The soilless medium–grown basil had the highest appearance liking and flavor intensity, followed by the greenhouse aquaponic grown and then by the warehouse aquaponic grown. Aquaponically grown cultivars were rated less bitter than soilless medium–grown cultivars.

Aquaponics, the combination of hydroponics and aquaculture into one growing system, is a controlled environment production system that potentially has increased environmental and consumer benefits over traditional production methods. There are many different ways to configure aquaponics systems that include different fish species, water circulation, lighting, plant species/density, and more. We tested three cultivars of lettuce, a common aquaponically produced crop, for yield in multiple aquaponic systems and conditions over a 13-month period in Minnesota. Four different aquaponic configurations and four types of fish were tested over the course of the experiment. There was no addition of supplemental nutrients to the systems to evaluate the differences between treatments and set a baseline. There was no difference in yield between lettuce produced aquaponically and those grown in soilless medium. However, there was a difference in yield between lettuce grown with different fish treatments. The tilapia treatment produced higher average yield than yellow perch. There was a difference between cultivars, with higher average yield from loose-leaf bunch cultivars (Salanova, Skyphos) than the bibb type (Rex). Average yield for all but one treatment was above that of reported commercial field production, making lettuce a competitive aquaponic crop in most systems.

The United States Food and Drug Administration and the Department of Agriculture jointly published the "Guide to Minimize Microbial Food Safety Hazards for Fresh Fruits and Vegetables," which is used as a basis for Good Agricultural Practices (GAP) audits. To understand barriers to incorporation of GAP by Minnesota vegetable farmers, a mail survey completed in 2008 was validated with visits to a subset of the farms. This was done to determine the extent to which actual practices matched perceived practices. Two hundred forty-six producers completed the mail survey, and 27 participated in the on-farm survey. Over 75% of the on-farm survey respondents produced vegetables on 10 acres or less and had 10 or fewer employees. Of 14 questions, excellent agreement between on-farm interviews and mail survey responses was observed on two questions, four questions had poor or slight agreement, and eight questions had no agreement. Ninety-two percent of respondents by mail said "they took measures to keep animals and pests out of packing and storage buildings." However, with the on-site visit only 45% met this requirement. Similarly, 81% of respondents by mail said "measures were taken to reduce the risk of wild and/or domestic animals entering into fruit and vegetable growing areas." With direct observation, 70% of farms actually had taken measures to keep animals out of the growing areas. Additional, on-farm assessments were done regarding employee hygiene, training, presence of animals, water sources, and composting practices. This validation study demonstrated the challenge of creating nonleading and concise questions that are not open to broad interpretation from the respondents. If mail surveys are used to assess GAP, they should include open-ended questions and ranking systems to better assess farm practices. To provide the most accurate survey data for educational purposes or GAP audits, on-farm visits are recommended.

To learn what areas should be emphasized in future educational good agricultural practices (GAPs) training efforts, a survey on usage of GAPs was mailed to 855 vegetable growers in Minnesota. We received a 32% response rate and a 43% cooperation rate. Over 65% of respondents reported compliance to proper worker hygiene practices, harvest container and tool sanitization and cleaning, water treatment to reduce the potential for microbial contamination, and protection of growing and stored vegetables from contamination. Small acreages and a diverse array of vegetables are typical characteristics of the majority of Minnesota vegetable farms. Seventy-seven percent of respondents farmed 15 acres or less. Most farms grew 10 or more different vegetable crops, and farmers markets, u-pick operations, and roadside stands were the most common marketing outlets. Overall responses to this study indicated that farmers currently believe they adhere to many recommended food safety best practices, but are lagging in key areas such as treating wash and processing water, taking measures to keep animals out of production fields, and cleaning and disinfecting harvesting tools and containers on a scheduled basis.

A partnership with the Hmong American community produced “The Wildlife and Wilderness Exploration Show,” a DVD that puts a modern twist on traditional Hmong storytelling. Key educational messages in the DVD were identified through interviews with Hmong natural resource professionals. The messages are delivered in entertaining segments in the DVD, which was created through collaboration with the Hmong arts and theater community. In contemporary Hmong American culture, DVDs are a popular form of entertainment and cultural learning, making the format appropriate for new refugees and elders with limited English proficiency, as well as the broader and multigenerational Hmong community.

Natural resource managers need to understand the cultures and concerns of ethnic minority communities in order to serve them effectively. The Hmong are an Asian ethnic group that is heavily involved in natural resource-related activities but has been largely overlooked by social scientists. We conducted a series of five focus groups with Hmong Americans in Minnesota and Wisconsin, exploring their experiences and perspectives on public lands. Our participants revealed deep cultural and personal connections with the natural world and the importance of public lands to many Hmong. But we also heard about profound problems and concerns. Perceptions of racism, discrimination, and harassment from public land managers and other agency personnel, recreationists, and private landowners are common. Participants had many suggestions for improvement and insights regarding the special needs of new refugees who arrived in the United States in recent years.

Hmong farm children perform different work tasks, have different roles and responsibilities, and are thus exposed to different hazards than most North American farm children. Hmong children perform tasks in four time-related phases: pre-harvest, harvest, post-harvest, and product marketing. Standard health and safety educational materials, including the North American Guidelines for Children's Agricultural Tasks, are not widely accepted by Minnesota Hmong farmers. This qualitative work is a precursor to the creation of culturally and contextually appropriate materials and guidelines to address the health and safety needs of Hmong children working on their family's production acreage. Methods used include literature review, focus groups, semistructured interviews, and field observations.

The industrialization of pork production is a gradual process. While operators are focused increasingly on production which is efficient and of high quality they must also be aware of the potential costs to their employees. The use of confinement facilities exposes workers to health and safety risks, which in turn may increase operating cost through increased health care and insurance costs. In order to protect employees, the employer needs knowledge about these risks, their impact on the operation, and methods of preventing injuries and illnesses. As operations grow in terms of the numbers of individuals employed, they must also be aware and compliant with state and federal health and safety regulations.

The pork production industry has increasing numbers of large producers using cost saving technologies which have the potential to pose health and safety hazards for employees working in these environments. The purpose of this study was to examine the needs of hog production employers related to providing a safe and healthy environment for employees, complying with federal and state health and safety regulations, and sources of outside assistance which are most helpful to these employers. A mailed survey assessing variables associated with demographics of producers, injury and illness experience, and strategies used in the prevention of injuries and illness, was sent to subscribers of National Hog Farmer magazine. In all operations and those with 10 or more employees, producers were most concerned about employees experiencing back/neck injury and slips or falls. Moving and handling animals was the most frequently reported task associated with injury or illness. Veterinarians and pork industry magazines were reported as the most useful sources of employee health and safety information for all producers. Producers report a need for training materials on first aid, animal handling and care techniques, air quality monitoring, and lung function testing for employees. Employee health and safety protection is part of doing business. This study provides important information for individuals and institutions promoting employee health and safety in the pork production industry.

Many Hmong refugees continue their cultural tradition of farming in the United States. The purpose of this project was to evaluate culturally based storytelling as a method to convey farming safety information to Hmong families. Hmong have an oral tradition; spoken stories are used to teach about heritage, as well as personal and social values, and end with a lesson or moral that can apply to their lives. Stories from "Orphan Boy the Farmer" illustrate hazards, behaviors, consequences, and control strategies related to farm work typical of Hmong farming in Minnesota and Wisconsin. The message of the 3 stories is that the successful farmer works safely and keeps his children safe from injury. Three stories were read, in Hmong, at 6 events in Minnesota and Wisconsin. Data were collected from 118 participants using focus group discussions. Transcripts were translated and analyzed to identify ideas and reactions to the stories expressed by participants. Findings indicate that storytelling was an appealing delivery method for most of the participants of this study. Participants were able to recount story content pertaining to farming safety and relate messages to their experiences dealing with hazards; unanticipated findings uncovered barriers to adopting safe practices. Several aspects of the storytelling performance influence its effectiveness. Development of folktale content and implementation of storytelling performances are described.

This literature review synthesizes available studies on Hmong agricultural practices, patterns of childhood growth and development of Hmong children in the context of injury prevention, and potential application or adaptation of the North American Guidelines for Children’s Agricultural Tasks (Lee and Marlenga, 1999) for Hmong children working in the U.S. Data from qualitative interviews, focus groups, case studies, and surveys were collected, categories were determined, and themes were identified. Field tools and practices, gender roles, and reasons for farming were examined, as well as physical and cognitive development of Hmong children and Hmong parenting techniques to describe factors related to farm task assignment of children. Current agricultural practices of Hmong in the U.S. can be described as generally small–scale operations that use mainly hand tools, manual labor, and local direct–marketing techniques. Specific practices include thinning, weeding, and hoeing; carrying tools, buckets, or baskets; setting plant supports; and watering. Hmong children appear to be given greater amounts of responsibility at earlier ages than North American children. Hmong parenting practices, as would be used in task assignment, are somewhat more authoritarian–based and lead to psychosocial skills that are more group–oriented than individual–oriented. Hmong children were found to be shorter than children in the U.S. of the same ages. This review suggests that the NAGCAT cannot be literally translated and disseminated to Hmong farming families as an injury prevention intervention. Further information is needed about what farm tasks Hmong children do and how Hmong parents assign those tasks to children.

Extension educators in 83 of 87 Minnesota counties were surveyed by phone to identify the level of current programming for children about farm safety and health, the program-related needs of the educators, and whether they were familiar with the North American Guidelines for Children’s Agricultural Tasks (NAGCAT). The survey results revealed that over 12,000 children in Minnesota were involved with farm safety and health educational programs through the University of Minnesota Extension Service during the year 2000. Additional resources educators requested included demonstration ideas, videos, and public service announcements. Thirty-four (41%) of the extension educators had heard of the NAGCAT and seven (8%) of them had been promoting the NAGCAT in their counties.

Farm stress is a major health and safety issue for farm families. The goal of this project was to assist people living and working in agricultural communities to develop strategies to protect themselves or others against the negative effects of stress using innovative educational modes and facilitating linkages with local resources.
