The food production environment introduces many potential points of contamination risk from the soil to the table. Consumer demand for food safety practices along with new government regulations for fresh produce have raised grower awareness of the need for best practices to reduce microbial risks during the production and processing of nuts, fruits and vegetables.
Produce Safety Courses Available in Northern California
Produce safety training courses offered through the Western Institute for Food Safety and Security (WIFSS) are informing the farming community about Good Agricultural Practices (GAPS) to reduce microbial risks and meet Food Safety Modernization Act (FSMA) training requirements. The FSMA Produce Safety Rule requires vegetable, nut, and fruit growers, to have at least one supervisor or responsible party on the produce farm who has successfully completed food safety training. The training courses are offered in English and Spanish and run through June 2019.
What to expect
The Produce Safety Alliance team at Cornell University developed the curriculum for the PSA Grower Training Courses working together with many growers, researchers, extension educators, produce industry members, and state and federal regulatory personnel.
Trainers, such as lead trainer David Goldenberg, food safety and security training coordinator at WIFSS, provide approximately seven hours of instruction time, which includes table top exercises and question and discussion time.
- An introduction to produce safety
- Worker health, hygiene, and training
- Soil amendments
- Wildlife, domesticated animals and land use
- Agricultural water, production water and post-harvest water
- Post harvest handling and sanitation, and how to develop a farm food safety plan
The Produce Safety Alliance Grower Training courses, underway since January of 2019, have been attended by vegetable, nut, and fruit growers from Butte County to Monterey County. David Goldenberg along with Aparna Gazula, farm advisor for small farms and specialty crops, with UC Agriculture and Natural Resources Cooperative Extension in Santa Clara County, conducted the first WIFSS training class. Assisting in the training with Goldenberg and Gazula were Avery Cromwell with the California Department of Food and Agriculture, and Donna Pahl, Cornell University, Produce Safety Alliance Extension Associate, with the Southwest Region, Riverside.
Benefits from attending the course
Course participants will be eligible to receive a certificate from the Association of Food and Drug Officials (AFDO) that verifies training course completion. To receive the certificate, you need to be present for the entire one-day course and submit the paperwork to your trainer at the end of the course.
Costs to attend
Sign up now for training courses to obtain a certificate of completion for the mandatory training to comply with the FSMA Produce Safety Rule. This is a chance to learn about foodborne illness and its impacts to the produce industry and consumers, different types of foodborne illness organisms, why prevention of contamination is critical to produce safety, how to conduct basic risk assessment, and steps involved in monitoring, record keeping, and corrective actions. CDFA, through a contract with the U.S. Food and Drug Administration (FDA), is subsidizing the cost of the training. A $30 cost per registrant will be charged to provide a lunch, beverages and the course manual and certificate completion.
Winter is the time when many backyard citrus trees and roadside fruit stands are laden with mandarins, lemons, navel oranges and limes. A UC Cooperative Extension expert is traveling the state to teach how the fresh taste of citrus can be preserved for year-round enjoyment.
UC Cooperative Extension Master Food Preserver coordinator Sue Mosbacher recently taught a roomful of attentive Mariposa County residents how to safely make marmalade jam, preserve lemons in salt to add flavor to savory dishes, and can grapefruit and orange sections with a little sugar to produce a fresh-tasting citrus cocktail high in vitamin C.
Mosbacher is a community education specialist based in El Dorado and Sacramento counties. But she has been driving up and down Highway 99 to bring research-based food preservation lessons to residents as far south as Madera County as part of a special project that was funded with a $140,000 specialty crops block grant from the California Department of Food and Agriculture.
Mosbacher has made dozens of appearances at county fairs and community meetings.
“It's been fabulous,” Mosbacher said. “People want the information and are using what they are learning.”
The series began last year with lessons focused on preserving summer fruit. The citrus classes are being offered in the winter. And in late spring 2019, Mosbacher will be on the road again to teach more fruit preservation classes and, in summer and fall of 2019, she will offer vegetable preservation lessons. The project is slated to conclude in 2020.
Mosbacher said she is energized for this journey by knowing that she is making a difference in California communities. She shared a telling story from a Georgetown vegetable preservation class. A participant said she had canned peas using the boiling water method; the Master Food Preserver Program guidelines require the use of a pressure canner for low-acid vegetables to prevent the growth of bacteria that produce the botulism toxin.
“She said she always canned peas in a water bath, and no one had ever died. But she came back the next week and told us she decided not to risk it and to throw the veggies to her chickens,” Mosbacher said. “And the next day, half her chickens died.”
Mosbacher has a background in computer science and the financial industry. During the 2008 downturn, she was laid off and spent time as a 4-H volunteer in the UC Cooperative Extension Office. While there, she learned about a part-time job opportunity working with UC Master Gardeners and UC Master Food Preservers.
At the time, she had no food preservation experience, so she took Master Food Preserver training.
“I learned everything I know from our own Master Food Preservers,” Mosbacher said.
Master Food Preservers are volunteer food preservation enthusiasts who have been trained in research-based preservation methods. Every food preserver training begins with a food safety primer with proven methods to decontaminate kitchen surfaces and tools, detoxify canned low-acid food and guard against spoilage.
At the citrus training, Mosbacher demonstrated canning a delicious orange jelly spiced with cinnamon, allspice and cloves. After cooking the juice with sugar and pectin, she canned the jelly using the boiling water method and with a steam canner. Either option is okay with high-acid citrus fruit.
Options for preserving lemons abounded. The juice can be frozen in an egg carton or ice cube tray, and used throughout the year in salad dressings, fruit salads, soups and ice cream. Slices of lemon can be dried to flavor ice water, seafood and casseroles. Mosbacher demonstrated preserving lemon wedges in salt water seasoned with bay leaves, cinnamon sticks and whole black peppercorns. She provided a recipe for a gourmet chicken tagine and roasted fingerling potatoes with preserved lemons to give participants guidance for using their preserved fruit.
At all the classes, participants are surveyed at the beginning and end to document the impact of the training. The preliminary results calculated with responses from 75 participants reflect positive results. After the class, nearly half of participants intended to preserve more fruit at home than they previously preserved. Two-thirds of participants intended to dehydrate more fruit than before.
"The results are great," said Katie Johnson, UC Cooperative Extension nutrition, family and consumer sciences advisor in the Central Sierra. "We never see results this high with regard to health behaviors, so I think it's pretty exciting."

Why do you love fruits and vegetables? Is it their bright colors? Their many shapes and varieties, the way they can makeover your plate with the seasons? The opportunity to taste local terroir in a very fresh bite of fruit or forkful of salad?
Is it more about the juiciness, crunchiness or succulence?
Or do you think more about nutrition? About vitamins, micronutrients and fiber, after decades of being encouraged to eat “5 A Day” to be healthy? Is it about that feeling of righteous virtue when you fill half your plate with fruits and vegetables — and know you're earning a gold star for eating right?
The importance of eating fruits and vegetables has been making headlines again recently, with studies refocusing on the concept of “nutrition security” in a changing climate and pushing for an emphasis on nutrient consumption. The EAT-Lancet commission — while mostly garnering headlines in the United States related to reduced meat consumption — also recommended a diet that would require almost every global region to increase its consumption of fruits and vegetables to meet healthy diet goals.
But there's another reason to love fruits and vegetables that might not be as obvious. Here's a 30-second video clip of what a young farmer in Uganda had to tell me about vegetables, when I had the chance to meet him last year:
“There's no quicker source of getting money in town,” Boaz Otieno explained, when discussing why he chose to farm instead of going to town to find a job. He also talked about the concept that he could grow vegetables like tomatoes on a smaller plot of land and earn as much for those tomatoes as a larger plot of corn or cassava.
"You might even grow (tomatoes) twice while the cassava is not yet harvested, so there's a lot of money in horticulture," he said.
Otieno is a farmer who was also working as a site coordinator for a research project led by Kate Scow in Uganda, which was supported by the Horticulture Innovation Lab, the USAID-funded research program that I work for at UC Davis. Elizabeth Mitcham, director of the Horticulture Innovation Lab and a UC Cooperative Extension specialist, often talks about the “double-duty impacts” of fruits and vegetables, as these crops can be a tool to achieve two major global goals: improving nutrition and reducing poverty.
And it's not just one farmer's opinion that horticultural crops can yield higher incomes. In a white paper about aligning the food system to meet fruit and vegetable dietary needs, the authors pointed out that data from Africa and Asia have shown farmer profits per hectare 3-14 times higher when growing vegetables versus growing rice. The paper also points out that USDA estimates fruits and vegetables account for 23 percent of production value in American agriculture, grown on less than 3 percent of the country's agricultural land. And here in California, fruits and vegetables are a $20 billion industry.
Later this month, the Horticulture Innovation Lab will be hosting a conference in Washington, D.C., focused on making the case for fruits and vegetables with the theme, “Colorful Harvest: From Feeding to Nourishing a Growing World.” The conference will bring together decision makers, international development practitioners, and researchers from universities across the United States, Africa, Asia and Central America to discuss how horticultural innovations can advance global issues of food security, food waste, gender empowerment, youth employment, malnutrition, and poverty reduction.
While the conference speakers and participants will be diverse, we're also working to bring farmers' voices — like Otieno's — into the conference with video clips from our partners in Nepal, Honduras, Rwanda and elsewhere, to explain what exactly it is that makes them love fruits and vegetables.

Eating healthy on a limited budget is possible, but any cuts in SNAP or rise in food costs make it harder
The affordability of healthy food is often cited as a barrier to low-income families eating nutritious meals. A new study published in the Journal of Nutrition Education and Behavior found that with menu planning and access to stores selling items in bulk, the average daily cost for serving healthy meals to a family of four was $25 in 2010 dollars. This cost was consistent with the US Department of Agriculture (USDA) low-income cost of food meal plan, but higher than the cost of the USDA Thrifty Food Plan. The Thrifty Food Plan is the meal plan used by the USDA to determine food assistance benefits.
“This study determined the likelihood that families living in low-income households could create meals that meet the USDA dietary guidelines presented in MyPlate nutrition education materials,” said lead author Karen M. Jetter, Ph.D., of the UC Agricultural Issues Center, which is part of UC Agriculture and Natural Resources. “In addition to food cost, the other factors considered were access to stores, time for meal preparation, and whether the menus included culturally appropriate foods.”
Jetter also cautioned that any reduction in SNAP, the federal Supplemental Nutrition Assistance Program for people with qualifying low incomes, or increase in food costs would make it hard for economically vulnerable families to eat healthy foods.
This project was conducted in collaboration with Northern Valley Indian Health, Inc, and the Mechoopda Indian Tribe of Chico Rancheria where 88 percent of the population surveyed lived in households with an income of less than or equal to $35,000 a year. The menus were created to feed a household with a father, mother, and children ages 7 and 10 with foods the Mechoopda Indian Tribe community liked to eat, met USDA guidelines for healthy eating, and had realistic portions. Menus did not rely on processed foods to reduce the amount of fat and salt in the family diet, were varied so the family would not become bored eating the same foods, did not always require hot meal preparation, and were affordable.
By working closely with the Mechoopda Indian Tribe community researchers, two-weeks of daily menus were developed using meal plans provided by the Mechoopda Indian Tribe community. Although these plans did not meet the nutritional guidelines every day, all categories achieved the recommended levels on average at the end of a two-week period.
“These menus showed that a healthy diet on a budget was achieved by balancing daily targets over two weeks, not every day. This focuses healthy eating on balance rather than being deprived,” said Jetter.
Once the menus were determined, the Mechoopda Indian Tribe community researchers visited 13 grocery stores in Chico to ascertain menu costs. The stores visited were within a 10-minute car ride of 76 percent of the Mechoopda Indian Tribe members and were classified as bulk supermarket, general supermarket, discount market, or specialty market such as a local co-op.
Both bulk and general supermarkets had the highest availability of the items needed for a two-week shopping list, whereas specialty and discount markets lacked as many as 52 of the items needed. Bulk and discount market baskets had the lowest average daily cost of $25, while the specialty market had the highest average cost of $39 per day.
One limitation of the study was the focus on the actual cost of food without considering transactional costs such as the time needed to plan menus, develop shopping lists, research store advertisements, and travel to the bulk supermarket that offered the lowest cost. All of these factors influence a family's ability to sustain a healthy eating plan.
“This research demonstrates that menus that meet USDA guidelines can be purchased by a family of four when shopping at a bulk supermarket, but any reduction in SNAP benefits or increase in food costs would make it difficult for these economically vulnerable families to maintain a healthy lifestyle,” stressed Jetter.
This project was part of a larger project funded by a National Institutes of Health grant.
U.S. honey industry contributes more than $4.7 billion to economy, according to Ag Issues Center report
The U.S. honey industry is thriving, according to a new study from the University of California Agricultural Issues Center (AIC). The research found that the U.S. honey industry in 2017 was responsible for more than 22,000 jobs and its total economic output was $4.74 billion. Total economic output includes direct effect, such as workers hired to move beehives, indirect effect, like packaging supply companies for honey products, and induced effects, the wages honey industry workers spend at local businesses.
The study was directed by Daniel A. Sumner, an economist and director of the AIC, an institute which has studied the economic impacts of many farm commodities. The U.S. honey industry is made up of beekeepers, importers, packers and processors.
"The U.S. honey industry contributed significantly to jobs and economic activity across many states and regions in the United States," Sumner said. "In addition to its direct economic contributions, as an important ingredient, honey contributes flavor to a wide variety of food products and stimulates demand across the food industry."
The honey industry contributed approximately $2.1 billion in value added to the U.S. gross domestic product (GDP) in 2017. For scale, Vermont Maple contributed $34 million to the Vermont economy in 2013.
"While beekeeping is a labor of love and the true essence of a craft industry, the honey industry's size and scope shows that honey production makes a significant impact on our nation's economy," said Margaret Lombard, CEO of the National Honey Board. "From beekeepers in Washington state to packers in Maine, the honey industry's impact is evident across the country—as well as in the overall U.S. GDP."
In 2017, the honey industry employed more than 22,000 individuals across the U.S. in production, importation and packing jobs. The Vermont Maple industry employed 4,021 in 2013.
In addition to a thriving industry, the American appetite for honey is growing. In 2017, Americans consumed 596 million pounds of honey or about 1.82 pounds of honey per person, which represents a 65 percent increase in consumption from 2009 to 2017.
