  • CDFA Urges Immediate Reporting of Grapevines Purchased at Costco

    The CDFA is urging anyone who purchased grapevines from Costco stores in Northern California between April 21 and May 21 to contact their local agricultural commissioner after an invasive pest was discovered among the 13,000 vines shipped during that period.

    Grapevines from a Fresno nursery shipped to California Costco stores in April and May were found to be carrying the glassy-winged sharpshooter (GWSS), an insect capable of spreading a potentially lethal vine disease.

    On May 19, the first glassy-winged sharpshooter was detected on vines sold at the warehouse retailer, triggering an immediate and widespread containment effort by CDFA, agricultural commissioners and winegrape growers throughout Northern California. Officials are responding to public reports, conducting inspections and public outreach and trapping near stores and locations where purchased vines were taken. They are also ensuring that potentially infested plants are safely contained and disposed of.

    In addition to destroying infested stock still in Costco warehouses, CDFA is working with agricultural commissioners and conducting public outreach to locate vines sold to consumers across 24 counties, as well as neighboring at-risk counties.

    “While many vines have been intercepted and destroyed, locating the thousands that may still be in customers’ hands remains our top priority,” said California Ag Secretary Karen Ross. “Anyone who purchased these vines should contact their local agricultural commissioner immediately.”

    Costco is offering a full refund to anyone who purchased these vines. Customers do not need to return the vines to receive a refund.

    To prevent the potential spread of the pest, CDFA officials urge customers to:

    •Immediately contact your county agricultural commissioner

    •Keep the plant in its original pot or container and away from other plants

    •If possible, place the plant inside two trash bags, one inside the other, and seal them closed

    •Do not place the plant in the trash or compost bin

    •An agricultural inspector will come, inspect the vine for GWSS and — if necessary — remove and dispose of the vine

    Winegrapes are one of California’s largest cash crops, generating approximately $73 billion annually in economic activity and supporting more than 422,000 jobs statewide. A 2025 economic study estimated that Pierce’s disease, which is spread by the glassy-winged sharpshooter, could cost California approximately $166 million annually if left unchecked.

    California first recognized the full threat of the glassy-winged sharpshooter in 1999, when a major Pierce’s disease outbreak in the Temecula Valley led to the destruction of more than 300 acres of vineyards. Winegrape growers quickly responded by working with the CDFA to create the Pierce’s Disease Glassy-Winged Sharpshooter Board to control the pest and find solutions to the disease it carries. The program has successfully contained GWSS for over 25 years. Visit cdfa.ca.gov/pdcp/PD_GWSS_Board.html. — Story Contributed by the California PD/GWSS Board

  • CDFA Release Final Recommendations on Food Safety, Water Quality Report

    The Newsom administration released the final recommendations from a study that intends to improve food safety and water quality reporting for California’s agricultural community. This interagency collaboration between the California Department of Food and Agriculture (CDFA), California Environmental Protection Agency (CalEPA), and the State Water Resources Control Board was developed with input from farmers, ranchers, and local leaders, and demonstrates California’s continued efforts to build a roadmap for the future.

    “I want to thank the many farmers, ranchers, local leaders and advocates, and agency colleagues who contributed to this work,” CDFA Secretary Karen Ross said. “You have helped us build a roadmap for smarter regulation – one that keeps pace with the complexity of today while preparing for the challenges of tomorrow. We look forward to aligning this report’s recommendations with future opportunities of parallel efforts underway.”

    “Innovative regulatory programs at the intersection of agriculture and water quality are critical to the state’s future,” said State Water Board Chair Joaquin Esquivel. “The State Water Board is proud to work alongside Secretary Ross and Secretary Garcia as we consider key recommendations from the agricultural community and other industry experts for these programs. One thing is clear: we must strengthen our data systems to maximize their value to decision makers and the public while minimizing the cost of compliance for growers. I look forward to working together to advance these programs for the benefit of all Californians.”

    The study evaluated California’s food safety and water quality regulatory requirements for agriculture as part of an effort to streamline administrative processes and optimize information collected by the state. The study was supported by funding in the 2021-22 budget.

    The report identifies 18 recommendations to streamline agency coordination, expand technical assistance, modernize data and reporting systems, and enhance regulatory efficiency while supporting food safety and environmental protection goals.

  • CDFA Accepting Proposals for Biologically Integrated Farming Systems Program

    The CDFA’s Office of Pesticide Consultation and Analysis (OPCA) is now accepting concept proposals for its Biologically Integrated Farming Systems Grant Program (BIFS). The BIFS grant program funds on-farm demonstration and evaluation of innovative, biologically based farming systems that employ sustainable pest management (SPM) strategies. These practices aim to reduce reliance on biologically disruptive pesticides while allowing growers to maintain yields and economic sustainability.

    Past BIFS projects have refined and promoted SPM practices such as areawide mating disruption, biological control via natural enemy releases and habitat planting, non-fumigant soil disinfestation, removing diseased plants, bio-pesticides and more across cropping systems.    

    The 2026-2027 Request for Proposals (RFP) identifies five priority funding areas based on recent or proposed regulatory actions and grower needs:

    • Areawide management
    • Monitoring that informs pest management
    • Post-harvest disease control
    • Neonicotinoid alternatives in tomato
    • Paraquat alternatives

    OPCA does not require BIFS project proposals to address one of the priority topics.

    This funding cycle includes $2 million in available grant funding, with up to $1 million per project. A portion of OPCA’s allocation of the pesticide mill assessment funds this solicitation.

    Following review of concept proposals, OPCA will notify applicants in late July 2026 and invite selected applicants to develop and submit a full proposal. Full proposals are due at the end of August 2026.

    Concept proposals are due by June 30 at 5 p.m. Public or private colleges and universities, local, state, and federal government entities including tribal governments, non-profit organizations, and commodity groups are eligible to apply.

  • Tomato Industry Taking Steps to Stop Spread of Parasitic Weed

    California’s processing tomato industry for the first time this past harvest season agreed to voluntary equipment cleaning and notification guidelines to prevent the spread of branched broomrape, a parasitic weed that attaches to roots and sucks out key nutrients.

    The weed’s tiny can be smaller than finely ground spices, survive dormant in soils for decades and be carried by wind, footwear and other methods. Its resurgence in 2017 in Yolo County threatens the productivity of an industry that brought in $1.6 billion in 2024.

    The University of California, Davis — in conjunction with industry — federal authorities and state regulators, is playing a key research role in the battle against broomrape by testing and developing in-field sanitation guidelines for tomato harvesters and other field equipment. Researchers across campus are also evaluating herbicide treatments, weeding methods, ways to detect the weed and disrupt its ability to affect crops.

    Harvesting with Conditions

    Under former state quarantine rules, any broomrape detection would require a field be destroyed before harvest. With the new guidelines, growers may harvest if they adhere to certain management practices, including equipment cleaning standards developed by the California Broomrape Board, formed in 2024 to advise the California Department of Food and Agriculture.

    “There’s 1,000 acres that are actually reported but we know from observation that it’s probably much greater than that,” said Cassandra Swett, a UC Davis plant pathologist who is leading efforts to sanitize field equipment. “There are two main goals: reduce the economic impacts of broomrape on growers in the affected region by allowing them to harvest, and on the other side, keep broomrape out of the regions that do not currently have it.”

    In 2025, nearly all growers and processors in the state signed on to compliance agreements regarding cleaning and notification, and this year the California Department of Food and Agriculture is expected to require them, said Zach Bagley, managing director of the California Tomato Research Institute, which has been working on broomrape control issues since 2018.

    “It’s overall seen as a positive in the industry,” Bagley said. “The driver for sanitation is not just the biology of this weed and the reality in the field, but it also has regulatory components.”

    Also, this year, all processing tomato canneries in the state have agreed to build on-site wash stations or set up cleaning protocols for the 2026 season to help stop the spread from harvest trailers.

    “We can never have a 100% guarantee that we’re not moving seed, but we can do our best to take it off in the fields where we know we have a problem, and that’s where the research comes in,” said Bagley, whose organization helps fund related UC Davis research.

    Effectiveness and Timing Key 

    Swett, fabricators with the Department of Biological and Agricultural Engineering, a Cooperative Extension farm advisor and others in the industry are working on prototypes of sanitizing equipment, evaluating spray nozzle size, water pressure, aim and other factors.

    Cleaning is no simple task, and it consists of removing debris with physical cleaning and sanitizing. The right combination of debris removal followed by a sanitizer can substantially reduce dispersal risk, Swett said.

    The goal is to reach under and around tractors and remove mud, soil, plant material or anything that can collect and carry broomrape seeds. Some versions of these prototype cleaning systems are in the field and others roll under the equipment.

    “These machines are running 24 hours a day,” Swett said. “Taking that downtime to clean the machine is really messing up harvest schedules.”

    At present, cleaning a tomato harvester can take hours, but industry is hoping it can get to less than an hour to meet labor, costs and logistics needs. “One of the drivers of this work has been, ‘How can we make it faster but still be acceptable at the end of the day?” Bagley said. Agricultural engineer Dan Frank and crop advisor Patricia Lazicki have developed and are testing prototypes of automated systems that can improve cleaning time and coverage, Swett said.

    A Better Picture

    Before the broomrape compliance agreements, it was difficult to determine how many of the 185,000 to 250,000 tomato production acres might be infected because reporting would mean losing a crop and the money invested on planting, irrigation and other efforts with no hope of insurance covering the loss.

    The agreements have changed that, said Brad Hanson, a professor of Cooperative Extension in plant sciences who is an ad hoc member of the Broomrape Control Board.

    “With the risk of crop quarantine off the table for growers under the compliance agreements, we can talk about the problem out in the open,” Hanson said. “The daylighting part of this has been really helpful because for the last five years, we’ve been really in the dark.”

    Now it’s about working toward a common solution, said Neil McRoberts, a UC Davis plant pathologist who researches ways to support plant health and regulations. He is also a non-voting member of the board and familiar with pests that have caused widespread damage to other crops. With broomrape, the attention is focused before the weed has spread widely across fields in California and potentially to other crops like carrots, potato and sunflower.

    “I’m hopeful because the issues are being faced very early on,” he said.  — By Emily C. Dooley, UC Davis

  • Citrus Greening Quarantine Expands in Southern California

    Effective immediately, the Animal and Plant Health Inspection Service (APHIS), in cooperation with the California Department of Food and Agriculture (CDFA), is expanding the area quarantined for citrus greening (Huanglongbing), caused by the Asian citrus psyllid, in California. APHIS is establishing a new quarantined area in the Ramona area of San Diego County of 93 square miles and is expanding the quarantined area in the Loma Linda area of San Bernardino and Riverside Counties by 26 square miles. These measures parallel the intrastate quarantines that CDFA established on March 2, and March 6, 2026, respectively. APHIS is taking this action because of citrus greening detections in plant tissue samples collected from residential properties. There are 25.16 acres of commercial citrus impacted by the new Ramona quarantine and 411.47 acres of commercial citrus impacted by the Loma Linda area expansion.

    APHIS is applying safeguarding measures outlined in 7 CFR 301.76 and Federal Orders pertaining to the interstate movement of regulated articles from the quarantined areas in California. This action is necessary to prevent the spread of citrus greening to non-infested areas of the United States.

    The APHIS Citrus Greening webpage contains specific changes to the quarantined areas in California. APHIS will publish a notice of this change in the Federal Register.

  • CDFA Expands Orange Scab Quarantine Boundary in La Puente

    The California Department of Food and Agriculture (CDFA) announced it is expanding its sweet orange scab (SOS) quarantine in the La Puente area of Los Angeles County (grids 456 and 457). The quarantine is effective as of April 8.

    SOS is believed to be caused by Elsinöe australis, a fungal pathogen. The disease results in the formation of pustules and lesions on the skin of the citrus.

    Regulated articles and conditions for intrastate movement under the quarantine can be found at Title 3 of the California Code of Regulations section 3443. Interested parties and local entities may request to lift the quarantine area designations by submitting a written appeal supported by convincing evidence. Appeals must be filed within 10 working days of the notification. Quarantines will remain in effect during the appeal’s pending. Appeals can be mailed to: CDFA – Citrus Division 1220 N. St. Sacramento, CA 95814.

  • FDA and Partners in the Central Coast Share Findings from Environmental Study

    Today, the U.S. Food and Drug Administration is sharing initial findings from a multi-year environmental study conducted in California’s Central Coast agricultural region that will inform efforts to further improve the safety of produce — an essential component of a healthy diet. The California Longitudinal Study was conducted in partnership with the Western Center for Food Safety at the University of California, Davis, the California Department of Food and Agriculture, and regional agricultural stakeholders.

    The Central Coast of California is farmed year-round and supplies a large volume of produce, which includes more than 400 commodities. However, there have been periodic foodborne illness outbreaks associated with the region, including several that occurred between 2016 and 2020 caused by the same E. coli O157:H7 strain. This study sought to identify environmental factors that significantly contribute to the introduction, persistence, and spread of foodborne pathogens that could contaminate produce prior to harvest. Increasing our understanding of the ecology of this growing region as it pertains to foodborne pathogens is to the benefit of consumers, producers, academia, and food safety officials as it allows for continued improvement in best growing practices to enhance food safety.

    The longitudinal study, which began in 2020, followed an adaptive research design in which sample collection matrices, sites, and frequencies were continually assessed and refined to obtain maximum useful, practical information. Through repeated sample collection, testing, measurement, and analysis, the research team observed trends in pathogen presence in this region over time, providing insightful information on prevalence, location, and potentially influencing factors such as seasonality, weather conditions, and domesticated and wild animal activities on adjacent and nearby land.

    Initial findings related to E. coli O157:H7 and other Shiga toxin-producing Escherichia coli (STEC) have been posted to the FDA’s California Longitudinal Study webpage and are summarized below:

    Animal Sources of Contamination: Fecal samples from rangeland beef cattle, feral pigs, deer, birds, and coyotes were frequent sources of STEC. Viable STEC was recovered from fresh and older, drier feces from livestock and wildlife found in the sampling area. These results suggest that STEC may remain viable in fecal material for extended periods.

    Environmental Sources of Contamination: Surface waters and associated sediments may facilitate STEC persistence, and in the case of water, STEC movement in the region. STEC was not recovered in a substantial amount of soil or air samples, indicating that these are not likely impacting the spread of STEC in the region. However, STEC was observed in water and sediment from rivers and creeks, and to a lesser extent in irrigation tailwater and tailwater sediment (accumulations of field runoff from irrigation practices) collected at field edges.

    STEC Diversity, Persistence, and Movement: Twelve different E. coli O157:H7 strains were isolated from environmental samples; however, the strain responsible for outbreaks between 2016 and 2020 was not recovered. STEC isolated from wildlife feces genetically matched strains from cattle feces, other wildlife feces, and in some cases, water, sediment, and soil. Six different highly pathogenic STEC serotypes were identified and some strains of these serotypes persisted for nearly two years.

    The FDA will engage with stakeholders to further discuss the data and findings from this study and assist stakeholder efforts to develop practices to manage the risks posed by the potential sources of contamination. Additional information and publications will be added to FDA’s California Longitudinal Study webpage as they become available. — By the U.S. Food and Drug Administration

  • Cal Ag Secretary Karen Ross Highlights International Year of the Woman Farmer

    California Secretary of Agriculture Karen Ross highlighted the International Year of the Woman Farmer during the World Ag Expo in Tulare, CA; a campaign prompted by the United Nations and the CA Grown program to raise awareness and promote the essential global role women hold in the agriculture industry, from production to trade. 

    “Women are helping to grow the future of California Agriculture.  The number of dynamic, fearless, accomplished women leading farms, driving innovation and shaping the future of food has grown more than 13 percent in the last decade,” said Karen Ross, California Secretary of Agriculture.  “We need to celebrate their contributions to the global agricultural industry here at the World Ag Expo where we are witnessing cutting edge technology, equipment and educational opportunities, and every day.”

    California is home to over 45,000 women producers who collectively steward more than 11 million acres of farmland.  Women play essential roles across the food system that are critical to food security, nutrition and economic resilience.  Their essential role in every facet of the food and farming system is celebrated at the World Ag Expo, where more than 100,000 visitors from 70 countries are scheduled to visit.  The event hosts over 1,200 exhibitors displaying state-of-the-art technology and equipment over a three-day period, as well as educational opportunities, including seminars by agricultural experts and cooking demonstrations by California Grown.

    Secretary Ross was joined at the International Year of the Woman Farmer event by CDFA Undersecretary Christine Birdsong. CDFA representation at this year’s World Ag Expo also includes Deputy Secretary Arima Kozina and staff from the department’s Office of Agricultural Resilience and Sustainability (OARS) and Inspection Services Division, as well as the State Board of Food and Agriculture.

    Food influencers including Alison Needham a creator for the California Grown campaign, Aida Mollenkamp the founder of Salt and Wind Travel, prune grower Hilary Porter of Erick Nielsen Enterprises, U.S. Sweet Potato Council President Sarah Alvarnaz, and many more women in agriculture are in attendance during a reception to honor their contributions.

    The California Grown program brings together industry and government resources to increase the awareness, consumption and value of California agricultural products, helping consumers enjoy the best of the California lifestyle, and to recognize the Golden State’s role in food, beverage and flower production across the nation and the globe.
