Winter season: A time for food safety systems re-evaluation and education for food hubs

The holiday meal season is often a busy time for food hubs – entities that handle the aggregation, distribution and/or marketing of source-identified regional food – as restaurants, retailers and consumers fill their tables and shelves with an abundance of fresh, local products. However, the subsequent winter months can provide a valuable time for reflection and re-evaluation of a food hub's systems and processes. In this spirit, it may be helpful to remind people working at food hubs that University of California Sustainable Agriculture Research and Education Program (UC SAREP)  offers a suite of food-safety resources – in English and in Spanish – on its website. 

Educational resources include: 

• A step-by-step guide for food hubs on how to pursue a third-party food safety audit with guidance on how to navigate buyers' questions.
• Two sample food-safety plans intended as a starting point to be adapted to a food hub's specific operations and practices.
• Example standard operating procedure, or SOP, documents related to 11 common tasks carried out by food hubs.

“We hope these resources can play a role in helping food hubs to adopt best practices and control risks related to food safety,” says Gwenael Engelskirchen, sustainable food and farming coordinator with UC SAREP,  who led the development of these educational tools. 

According to the Centers for Disease Control and Prevention, approximately, 1 in 6 Americans (or 48 million people) gets sick and 3,000 die of foodborne diseases annually. In 2011, to help prevent the occurrence of foodborne illness, the federal government enacted the Food Safety Modernization Act (FSMA), designed to outline actions to be taken at various points along the supply chain for both human and animal food. 

UC SAREP's Food Safety Resources for Food Hubs are intended to help food hubs navigate these food-safety regulations and accompanying best practices. Resources are also available in Spanish at Recursos de seguridad alimentaria para los centros de distribución de alimentos. 

Food safety certification guide

Some buyers verify a supplier's food safety program by requiring an audit performed by a third-party certification body or auditing company. This Guide to Food Safety Certification offers key considerations before deciding to pursue a food safety audit and helps users navigate the food safety certification process. 

Food safety plan

Food hubs that meet the criteria for full compliance with FSMA's Preventive Controls for Human Food Rule are required to have a food-safety plan in place. And for all food hubs, having a shared document describing the facility's operations and how potential risks of food contamination are managed is a good idea. Two sample food safety plans, inspired by the operations of food hubs in California, provide a starting point and can be adapted to a hub's own operations. 

Standard operating procedures

Standard operating procedures provide detailed step-by-step instructions for how to carry out operational tasks within a food facility. The standard operating procedure samples cover common topics such as handwashing, facility cleaning and more, and are intended to be adapted to a food hub's specific operations and practices. 

Jacob Weiss from Spork Food Hub in Davis said, “the templates were a great starting place for us to build the framework of our food safety plan. It helped us figure out what we needed to (and didn't) need to include. I think the SOPs are also really useful because they are broad enough to get you started but flexible enough to add the specific practices of your business or hub.”

These resources and tools were developed in collaboration with various project partners, including Department of Food Science and Technology at UC Davis, Department of Population Health and Reproduction at UC Davis School of Veterinary Medicine, Center for Precision Medicine and Data Science at UC Davis Health, and Community Alliance with Family Farmers.

Desert Research and Extension Center hosts international agriculture student interns

Caring for feedlot cattle, examining onion irrigation practices, and teaching preschoolers about agriculture are not part of the typical college curriculum. But for Desert Research and Extension Center's five college student interns, these activities are what fill their days.

Located on 255 acres of Southern California desert, DREC focuses on advancing irrigated desert agriculture, livestock and feedlot management, and pest management. It is also home to the Farm Smart agricultural education program, reaching approximately 7,800 participants annually.

In February, DREC welcomed the college student interns - creative thinkers working at the intersection of experimental research and agriculture education. During the internship, the students are working on-site under the mentorship of academics and staff members on applied projects. After years of COVID restrictions, the center is excited to welcome the students in person for hands-on engagement with the research and the public.

"Hosting students at DREC helps us to fulfill our mission while training the next generation of professionals," says Jairo Diaz, Director of DREC. "I am particularly motivated to provide experiential learning activities to underrepresented groups in agriculture and STEM careers."

Read on to learn about each of these budding agronomists.

Dianely Alba

Dianely Alba is majoring in agronomy at the Universidad Autonoma de Baja California, Mexico (This university is about 20 miles south of DREC). She is working under the mentorship of Jairo Diaz-Ramirez on a project focused on improving irrigation and nutrient management practices in onion production in Imperial County.

Melina Munoz

Melina Munoz is a student at Imperial Valley College studying elementary education. She is an intern for DREC's Farm to Preschool Festival. Munoz is in charge of developing and translating activities, planning and implementing the festival, and data entry for participant registration and evaluation information.

Lester Nolasco

Lester Nolasco grew up on a farm in Honduras, so he has been involved with animals and agriculture from a young age. He is working under the mentorship of Pedro Carvalho, the Feedlot Management Specialist. Nolasco is currently working on feedlot cattle management and beef cattle nutrition. 

“Although my passion is cattle, when you work with these animals, you indirectly learn about agriculture and crops in general because that is also an important part of cattle nutrition,”says Nolasco. Alongside the other feedlot management interns, Nolasco feeds animals, cleans pens, mixes feed, weighs cattle, and does lab work. “It is such a nice experience for me because I had only worked with dairy cattle in the past and this internship is teaching me a lot. I would like to learn as much as I can about beef cattle nutrition. Hopefully, in the future, I will be a professor and share the knowledge I have learned with other professionals back in my country.”

Heitor Otávio Martins de Oliveira

Heitor Otávio Martins de Oliveira has worked with animals throughout his life, starting with his parents' farm. He attended veterinary school, where he continued to learn about agriculture. At DREC, Otávio Martins de Oliveira is working on beef cattle nutrition management. In addition to daily maintenance tasks, he weighs the cattle monthly and provides any necessary treatments. 

“I would like to get as much knowledge as I can about nutrition in the USA and then return to my home country of Brazil to work there,” says Otávio Martins de Oliveira. “Maybe I will get a master's degree related to reproduction in cattle.”

Willi Meireles

Willi Meireles was introduced to Carvalho by his professor in Brazil. He is working on evaluating the use of feed additives to increase the performance of feedlot cattle.

“My grandparents own a farm where beef cattle are raised, so since I was a child, I have worked with animals and always liked animal science,” reflects Meireles. “I intend to specialize in ruminant nutrition and, after working hard, be able to have my own beef cattle.”

Youth-run garden provides 10,000 pounds of produce for San Diego families

UC SAREP's Sustainable Agriculture and Food Systems grant helps support Second Chance garden

Fifteen-year-old Xavier knows the anger within him will never leave. “I can't ever get rid of it,” he said.

“I've always wanted to just fight for no reason; I just had an anger issue, losing my temper quick with people,” added Xavier, a ninth-grader in San Diego County. “I have high expectations of myself.”

Xavier is working to keep his emotions under control, and he has found a sense of calm through his volunteer work. He was an intern – and then a peer supervisor – in the youth-run garden of Second Chance, a San Diego-based organization that works to break the cycles of poverty and incarceration by providing housing and job training to adults and young people.

Operating their garden as a small farm business, youth in the program, ages 14 to 21, offer produce to the community through their farm stand and a CSA (Community Supported Agriculture) model.

“The project incorporates a ‘farm to fork' approach in which youth not only experience how to grow food, but how to cook and eat healthfully,” said Gail Feenstra, director of the University of California Sustainable Agriculture Research and Education Program, which has a grant program that funds research and education projects – such as the youth garden – supporting sustainable food systems.

“Second Chance works primarily with youth in communities of color, providing them with training and also helping them develop confidence in themselves,” Feenstra said.

Filling a critical need for fresh produce

Caelli Wright, program manager of the Second Chance youth garden, said that grant funds from SAREP – a program of UC Agriculture and Natural Resources – have been used to purchase the supplies needed to sustain the program. The garden has filled a critical need for produce during the COVID-19 pandemic.

“After the pandemic hit, we recognized the increased need for fresh food in our neighborhoods,” Wright said. “That need was already there – southeast San Diego is considered a ‘food swamp' or ‘food apartheid', if you will – and with the onset of COVID, that need just escalated with unemployment and complications in our food production systems.”

Through a partnership with UC San Diego Center for Community Health and Encanto Elementary School (located down the block from the garden), donations enabled the program to give its CSA shares to about 25 families at Encanto. Over the course of the pandemic, the youth have grown 10,000 pounds of produce to donate.

At the same time, the program helps the young participants grow. For Xavier, being outdoors with peers empowered him to develop positive relationships. Previously, as a student in a charter school program, he was not accustomed to interacting with people and groups. Volunteering in the youth garden has given him a fresh perspective and understanding of others.

“Learning to be patient with people and [to] accept sometimes that if I don't know something, I need to ask about it, because I used to be so in my ego that I thought I knew everything,” Xavier explained. “But I don't know everything – I just learned to accept some things…that's just being part of life. And that's something that the garden has helped me with, personally.”

Opportunities for personal, social growth

Developing – and redeveloping – social skills are especially important for students, as they return from the disconnections associated with remote learning.

“Right now, with a lot of students facing the aftermath of COVID and being restricted to learning at home and not getting as much social interaction in their daily lives, it's led to a lot of challenges, mental health-wise, and social and emotional learning-wise,” Wright said. “The garden program provides that opportunity that some youth have been missing out on.”

In southeast San Diego, such crucial opportunities for personal growth and career exploration are harder to come by, and Second Chance started the garden in 2012 to give youth a unique work experience and valuable skills. About 400 young people have participated in the program.

“The youth that we serve are coming from low-income neighborhoods that are underserved with resources,” Wright said. “They just are not exposed to the same opportunities [as those in higher-income areas] to build skills or be ready for the workforce or to reach higher education – so that's where our program comes in and helps deliver those needed services.”

Xavier, who originally came to the garden because he heard that landscaping could be a lucrative career, recently finished his second stint as a peer supervisor in the youth garden. With his new skills, he and his cousin are looking to start a business of their own, cutting grass and doing yardwork in their community.

And, late last month, Xavier transferred to a more traditional high school environment.

“Being in a charter school after two, three years,” he said, “I've realized I miss being around more people.”
