Non Technical Summary
The long-term goal of this Collaborative Education and Training Project is to decrease potential food safety risks related to the production and distribution of microgreens--an emerging salad crop for which minimal information is available. First, we will characterize production and distribution aspects of the microgreens industry. Next, we will develop i) novel food safety training curriculum targeting the niche group of microgreens producers and ii) guidance documents for buyers and regulators of microgreens. The add-on curriculum facilitates integration of the FSMA Produce Safety rule among microgreen growers across the U.S. The proposed research will fill gaps in our current knowledge regarding production practices and operational characteristics of microgreens producers. Microgreens operations are more likely to implement recommended practices customized to meet their specific needs as opposed to generic produce safety recommendations available through PSA grower training courses. Moreover, guidance materials to assist consumers, buyers, and regulators navigating through the emerging microgreens industry will be created. The proposed work specifically addresses the Food Safety Outreach program priority to deliver "customized training to very specific target audiences."

Goals / Objectives
The long-term goal of this Collaborative Education and Training Project is to decrease potential food safety risks related to the production and distribution of microgreens--an emerging salad crop for which minimal information is available. A first step to achieving this goal is to characterize production practices, facilities, and distribution aspects of the microgreens industry. An intermediate step will be to develop i) novel food safety outreach 'add-on' curriculum targeting the niche group of microgreens producers and ii) guidance documents for buyers and regulators of microgreens. The add-on curriculum aims to facilitate integration of the Food Safety Modernization Act (FSMA) Produce Safety rule among microgreen growers across the United States. The five primary objectives to achieve our long-term goal are:Characterize production and distribution aspects of the microgreens industry.Determine barriers to implementation of risk management practices within microgreens operations using environmental assessments.Utilize science-based evidence to develop commodity-specific training for producers of microgreens.Utilize science-based evidence and regulatory standards to develop commodity-specific guidance documents for buyers and regulators of microgreens.Deliver and evaluate novel outreach materials targeting producers, buyers, and regulators of microgreens.
Project Methods
Activities and Sequence ProposedCharacterize production and distribution aspects of the microgreens industry: Initially, a comprehensive list of microgreens growing operations and producers will be created. To do this we will utilize members of the Project Management Team which include organizations that provide forums for microgreens producers (i.e., iGrow and Microgreens Facebook group) to exchange information, and word of mouth through cooperating producers and posting information with organizations. To recruit producers for our study, we will email producers, explaining the purpose of the study. Next, we will call producers to screen for eligibility and secure their participation. Data about production practices, farm characteristics, employee training requirements, and commonly used and preferred sources for food safety information will be collected from participating producers. We will also collect data about characteristics of the business operation, (i.e. growing operation start date, agricultural products grown, number and demographic characteristics of employees, structure (full/part-time), and average tenure of employees, sales, sales activity), operating costs, and sustainability. Combined, these data will allow for an in-depth characterization of microgreens growing operations.Determine barriers to implementation of risk management practices within microgreens operations using environmental assessments: Global GAP, and USDA Audit checklists to create an environmental assessment (EA) form specifically tailored to microgreens growing operations. We will also incorporate the GAP guidelines for greenhouse vegetable crops developed by the Food and Agriculture Organization of the United Nations (FAO), although it is not specific to microgreens production. Last, we will consider the Greenhouse Audit Guidelines checklist provided by PrimusLabs. The instrument will be designed to describe and assess characteristics and practices associated with implementation of risk management strategies. The EA tools will be informed by our findings from the producer surveys and interviews (Objective 1). For example, potential modifications or customization will be developed for the type of production system (fully indoors, greenhouse, split system) as well as type of operation (growing operation, home, restaurant, combination).Utilize science-based evidence to develop commodity-specific training for producers of microgreens: Based on the results of the survey/interviews and the environmental assessments, we will create a commodity-specific curriculum to facilitate integration of the FSMA Produce Safety Rule among microgreens growers in the United States. An English-language, commodity-specific curriculum (lesson plan, interactive activities, evaluation tools) will be developed for use with microgreens growers. The training sessions will be online and include video demonstration and animation, as we believe this approach is more conducive to the needs of microgreens growers.Utilize science-based evidence and regulatory standards to develop commodity-specific guidance documents for buyers and regulators of microgreens: Based on the results of the survey/interviews and the environmental assessments, we will create commodity-specific guidance to assist buyers with understanding microgreens production, quality, and safe handling practices. We will create guidance to disseminate to state health officials and regulatory agencies to use in periodic inspector training. A national webinar will be held in partnership with national regulators to provide clarification on the body of regulations that impact this industry, and these materials will be offered to state health officials for periodic training. During the webinar and accompanying the materials to state departments of health, a short survey will be provided to get baseline data on regulators' perception of practices allowed or prohibited by state and federal food policy.Deliver and evaluate novel outreach materials targeting producers, buyers, and regulators of microgreen: To evaluate curriculum effect, we will employ a randomized experimental design using a waitlist control group to determine effect of the commodity-specific training materials (Objective 3). We will recruit at least 100 microgreens growers, who will agree to complete the training. Using a random assignment process, one-half of participating producers will be assigned to receive training during the study period. This group will receive the commodity-specific training and will serve as the treatment group. The remaining growers will be placed on a waitlist and receive the training at the end of the study period, serving as the control group. Both groups will complete pre- and post-test surveys. Tests of the effect of training on risk management practices will be conducted by measuring self-reported changes in key risk management practices pre- to post-intervention in the treatment group against changes in key risk management practices pre- to post-intervention among the control group, with the null hypothesis of no difference between groups. State Restaurant Associations will be contacted to identify personnel responsible for communicating policy changes, business opportunities, or marketing programs to member restaurants. These personnel typically provide support to restaurant owners, operators, and managers. These personnel will be asked to disseminate guidance documents and promote participation in the online educational sessions. In addition, state Departments of Health or other appropriate state entities will be contacted to identify the supervisors of environmental health programs responsible for working with direct-to-consumer, retail, and manufacturing food businesses that are monitored or regulated by the state. These departments typically receive requests for technical assistance about proper food safety practices related to produce, harvest, processing, and food sales. The Association of Food and Drug Officials (AFDO) will also aid in engagement of regulators. Supervisors of these programs will be asked to disseminate guidance documents and promote participation in the online educational sessions and webinar to the field inspectors and clientele. Similar to the training materials created for microgreens producers, the corresponding guidance documents will be reviewed by a sample of buyers and regulators. Using a survey methods approach, we will ask questions about clarity, accuracy, practicality, and overall ease of use. Multimedia tools -which may include infographics, animations, videos, or interactive modules - will be distributed via multiple methods: at mobile demonstration events, through university Extension networks, and through direct engagement of stakeholders at industry and professional meetings. As well as at the project website, media tools will be posted at YouTube and on social media and contributed to educational portals such as eXtension and Cal State's MERLOT.

Target Audience:Microgreens producers or potential producers, regulators responsible for produce safety, buyers of microgreens, and consumers of microgreens. Changes/Problems: Nothing Reported What opportunities for training and professional development has the project provided?Graduate students have been involved in research, publications, and presentations. How have the results been disseminated to communities of interest?The results have mainly been communicated through presentations, publications, social media, and the website which includes trianing and outreach materials. What do you plan to do during the next reporting period to accomplish the goals? Nothing Reported

Impacts
What was accomplished under these goals? Objective 1: Conducted 48 interviews with microgreens growers to collect data about challenges with implementation of risk management practices. Key reported challenges included temperature/humidity; mold growth; no need for handwash signage as most are single worker operations; few had formal traceability systems; minimal recordkeeping; lack of understanding about the difference between sanitizing, cleaning, and disinfection. Objective 2: Explored the ability to conduct remote environmental assessments and developed a checklist. However, due to COVID19 and logistics, we chose to not pursue this objective. However, during the grower interviews, we were able to see several microgreens growing spaces. Objective 3:We have developed various training tools/messaging for growers and consumers which are housed on the all-about-microgreens.org website. The tools for growers include 1) Video -Cleaning and sanitizing microgreens equipment; 2) Interactive module -Keep surfaces clean; 3) Video - choosing a sanitizer; 4) Resource -Are you covered by the Produce Rule?; 5) Resource - Record Keeping (how to and templates); 6) Resource- Labeling (how to and templates); 7) Resource - Farm food safety plan (how to and templates); 8) Resource -On-farm decision tree project; 9) Resource - Standard operating procedures (SOP)(how to and templates); and 10) Resource - Where to get help.The information for consumers includeshow to handle and prepare micogreens and is hosted on the all-about-microgreens.org website. Objective 4:We were not able to develop specific guidance documents, but we have provided best practices on the website. Objective 5:We will continue to evaluated trianing materials as they are accessed.

Target Audience:Microgreens producers or potential producers, regulators responsible for produce safety, buyers of microgreens, consumers of microgreens. Changes/Problems:We have decided not to move forward with the environmental assessments of microgreen grower facilities. However, we have several collaborators across the grower scale who have allowed us to see their facilities virtually to be understand the "norm". What opportunities for training and professional development has the project provided?This project has provided multiple opportunities for mentorship and professional development of students. Undergraduate and graduate students have worked on research methods and manuscript writing which has enhanced their career and job prospects in the industry. Several members of the NMSU design team have begun exploring Microgreens educational forums, digital resources and online tools; have scheduled a trip to a microgreens facility and have explored Farmer's Markets and other distribution sites. The LRSF Team has provided TA to 7 microgreens growers during this reporting period. How have the results been disseminated to communities of interest?During interviews with growers, there were many discussions about information that we have collected and future diseemination efforts. Consumer survey has been published. Microgreens safety articles have been highlighted by lead institution. What do you plan to do during the next reporting period to accomplish the goals?We plan to: Partner with AFDO to host a national webinar providing education on regulations and practices related to the microgreens industry. Publish study on microgreen interviews. Design and provide educational training tools for microgreens growers.

Objective 2: Explored the ability to conduct remote environmental assessments and developed a checklist. Objective 3: In person collaboration meeting with PIs and Game Lab at NMSU to design training tools for microgreen growers and other stakeholders using the data collected in Objective 1 to determine specific gaps and needs for grower community. Determine critical areas of relavance specific to the microgreen grower community to focus training and design efforts; example: cleaning and sanitizing, preventing cross-contamination. Based on this, we have strategy for training adn education tool development. Objective 4: Train the Regulatory Virtual Forum, August 23, 2022; The UADA Local, Regional, and Safe Foods (LRSF) Team hosted a virtual forum for Environmental Health Officials and County Agents on understanding how to provide technical information to home-based food producers and microgreens growers. There were 72 paricipants. Survey (46 respondents); 72% of respondents did not know the regulations on microgreens or where to find information to provide to clients requesting technical assistance; 26% of respondents had received request for starting and operating microgreens operations. Hosted 3 planning sesssions with food safety specialists, Arkansas Department of Health Environmental Health Administrators, and National Ag Law Center to design an educational forum to update county level service providers on regulations and practices and to seek feedback on challenges with technical requests. The LRSF Team participated in 3 planning meetings during this period with the Microgreens project team to advise on curriculum and outreach material design. Objective 5: Survey-based study on consumer practices and perceptions was completed and accepted for publication in Food Control. The survey was designed by graduate students and data was collected with the help of Qualtrics Inc. Data was collected from 660 individuals across 50 states. Consumers were confident in their ability to safely store and handle microgreens safely 38.9 and 39.8% of the time, respectively, and nearly three-quarters (71.3%) of all consumers washed microgreens. Consumers were mostly ambiguous on whether eating microgreens could result in foodborne illness (24.7%) and felt that microgreens were as safe as fresh produce (37.9%) in general. Based on the above, a social media campagin targeting consumers was launched and all-about-microgreens.com

Outputs
Target Audience:Microgreens producers or potential producers, regulators responsible for produce safety, buyers of microgreens, consumers of microgreens. Changes/Problems:Because of the COVID-19 pandemic, we are having to rethink how we will conduct the on-site environmental assessments. What opportunities for training and professional development has the project provided?Two undergraduate students have been part of this project at the University of Houston as part of an internal food safety scholarship. One helped with survey design, and the other student was involved with data dissemination. One PhD student from the University of Arkansas lead teh microgreens consumer survey design and data analysis. At NMSU, several members of the design team have begun exploring Microgreens educational forums, digital resources and online tools, have scheduled a trip to a microgreens facility, and have explored Farmer's Markets and other distribution sites. How have the results been disseminated to communities of interest? Nothing Reported What do you plan to do during the next reporting period to accomplish the goals?University of Houston will assist the University of Arkansas on designing and getting the microgreens' consumers manuscript ready for submission to a scientific publication. A student at UH will assist with these effort providing additonal professional development opportunities. We will be completing the semi-structures interviews with microgreens growers as well as the environmental assessments. Once complete, we will begin design of training materials. We also plan to enage regulators to understand any potential regualtory grey areas or knowledge gaps related to microgreens growing practices.

Impacts
What was accomplished under these goals? Objective 1: We have completed a content analysis of over 200 Google and YouTube microgreens training materials. Analysis of accuracy and quality of over 200 Google and YouTube microgreens training materials. Most materials were of acceptable quality but few explicitly addressed food safety issues. A manuscript describing the results has been drafted and is currently being edited. Objective 2: We are currently establishing a protocol to perform remote or virtual environmental assessments. These will be completed in Summer 2022. Objective 3: This will be developed based on Objectives 1 and 2. Objective 4: We have established a process for refining research into educational objectives for a social media campaign. We have begun message development and secured a new employee to guide production of social media resources. As part of Objective 4, a microgreen specific consumer food safety, handling, and perception survey was disseminated to consumers using the Qualtrics tool. A total of 681 valid data points were collected across the U.S (divided into 4 regions). The results showed that of all survey participants: 93% buy , 66% grow their own , and 71% wash their microgreens. In general, consumers do not believe that microgreens can cause foodborne illness and have strong social desirability bias regarding the likelihood of getting fooborne illness due to contaminated microgreens. The data were collated and feedback on data analysis has been provided. We are currently in the process of working on the manuscript for submission to a scientific journal. Objective 5: We will develop the training in Objective 3 first.
