Still providing the world with top-notch information
UC Davis has been a leading source of information for people handling, packaging and transporting crops since the beginnings of the Postharvest Research and Extension Center in 1979. Now, the center is strengthening its focus on the needs of industry, offering fresh courses, weaving strategic partnerships and expanding into digital media, all while building up its research capacity to better serve the needs of the produce industry.
“We're asking people in the industry, ‘How can we support you? How can we better listen to you?' We want people to know we're not disconnected know-it-alls,” said new center co-director Bárbara Blanco-Ulate, an associate professor in the UC Davis Department of Plant Sciences. “We're getting more faculty involvement, people with expertise in related fields such as quality engineering and safety, as well as bringing in emeriti faculty and people from around California. We're forming partnerships with organizations around the world, and we've opened up to people from other institutions around the country.”
“The larger the network, the more things we can do,” added fellow co-director Irwin R. Donis-Gonzalez, an associate professor of UC Cooperative Extension in the Department of Biological and Agricultural Engineering.
The foundation: Expanded research
The new co-directors will beef up the center's applied science component with the hiring of a research specialist. They aim to provide new information that can be used industry-wide as companies explore new ways to handle and store fresh produce.
“We're building the capacity to respond to industry requests for research,” Blanco-Ulate said.
New courses, national reach
Their first workshop, held recently, demonstrates the center's renewed vision and commitment to broad networking: The Agricultural Water Systems Workshop addressed current concerns around water management and risks to food safety. Partners in the course included the Western Growers Association, the University of Arizona, the University of Florida and Salinas-based Taylor Fresh Foods, Inc.
Courses given over the past several years that have been recorded will be posted to the center's new, online video library and to the center's YouTube channel.
“People can watch those courses for free,” Blanco-Ulate said. In addition, new courses will be offered in-person and hybrid.
The co-directors are working with the University of California to offer continuing and professional education credits to course participants.
Online resources – many for free!
The center's website features a database with scores of free product fact sheets, which are downloaded by users around the world. The fact sheets are so highly regarded that they are considered expert evidence in legal proceedings, Blanco-Ulate said. Visitors to the website can also find links to research papers published by UC Davis faculty, including seminal works by Adel Kader, who founded the center.
Books are offered through the center's online bookstore and include titles through UC Agriculture and Natural Resources. Ten new titles are being planned, including topic-specific updates taken from previous classics.
Debunking myths: Ethylene
A new newsletter deals with a new problem: Misinformation about food and food handling that spreads through social media. One example is the use of ethylene to ripen produce such as bananas, so that they can be safely stored until ready for the consumer.
“Ethylene is safe for humans and does not leave any harmful residue on produce,” Donis-Gonzalez wrote in the center's latest newsletter. Even better news, he added: The levels of ethylene used on food are a tiny fraction of the concentrations that would be needed to create an explosion, one of the false alarms being raised in social media.
Evolving with the times
After 47 years of service, these and more updates will keep the center at the forefront of an evolving postharvest world. The top goal: Meet the needs of agriculturalists, industry and consumers.
“We are adapting to new needs, with both the resources and the workshop we're offering,” Donis-Gonzalez said.
“As a land-grant institution, we take our outreach mission seriously,” Blanco-Ulate added.

California became the first state in the nation to enact a universal school meal policy in 2022. A new study published in Nutrients explores the benefits and challenges California schools experienced during the first year of implementing the new policy, sharing results from surveys completed by 430 California school foodservice professionals in March 2023. Benefits included increased meal participation and revenues, reduced meal debt and stigma, and improved meal quality and staff salaries. Schools experienced challenges related to product and ingredient availability, staffing shortages, logistical issues with vendors and distributors, and increased administrative burden due to the end of federal waivers and return of families needing to complete school meal applications for federal reimbursement. Schools reported that state funding and increased federal school meal reimbursement rates were key factors that supported policy implementation. Findings can be used to inform other states and jurisdictions considering similar policies. The study was published online in June 2024 by lead author Monica Zuercher from the Nutrition Policy Institute, additional NPI researchers Dania Orta-Aleman, Christina Hecht, Ken Hecht, Lorrene Ritchie and Wendi Gosliner, and collaborators Juliana Cohen, Michele Polacsek and Anisha Patel. The research was funded by California General Fund Senate Bill 170, Senate Bill 154 and Senate Bill 101.

As vacation season begins, people will be traveling much more in the coming months. Whether you'll be staying at a hotel, hostel, motel, rental home, or summer camp, you should always be on the lookout for bed bugs. A bed bug check takes only a few minutes to complete and can give you and your family peace of mind when staying at new places.
Bed bugs are small insects, but big enough to see with the naked eye. They are oval shaped, wingless, and reddish brown. Bed bugs feed only on human blood, usually at nighttime while we are sleeping.
It's important to remember that bed bugs can occur anywhere and are not always an indication of poor hygiene or care. Bed bugs can be moved to new places on furniture, luggage, clothing, and bedding.
Follow these steps to do a simple bed bug check:
- Leave luggage in the lobby, hallway, outside the door, or bathtub while you inspect the room.
- Check the bed. Look for signs of live bed bugs, shed skins, blood stains, or eggs.
- If staying in a pre-made bed, pull back the sheets and look around mattress seams, the boxspring and headboard, and behind the nightstand. A flashlight can be helpful when doing this. If there is just a mattress, such as at camps and hostels, inspect the seams of the mattress pad and lift it up to also look underneath.
- Check other areas of the room. Inspect any upholstered furniture, behind picture frames, and along baseboards. Most bed bugs will be around the bed if they are present.
When you return home from your stay, inspect any luggage for bed bugs that may have hitched a ride. People can pick up bed bugs while traveling on buses, trains, airplanes or other locations with upholstered seats. Clothing from your trip can be laundered on the hottest setting to kill any bed bugs that may have gone unnoticed.
Don't let bed bugs ruin your summer fun!

The federal Child and Adult Care Food Program, commonly known as CACFP, ensures over 4.2 million children, mostly in families with low income, receive nutritious meals and snacks in childcare. However, not all qualifying childcare providers participate in this beneficial program. Research suggests that the serious deficiency process, designed to ensure program integrity, may hinder participation. Interviews with ten California CACFP sponsors—who administer the program for family childcare home providers and some centers—highlight key issues. Sponsors find the process too harsh, disqualifying providers for simple mistakes, creating equity issues for those with limited technology skills or non-English speakers, and being subjective, unclear and time consuming. These findings are timely as the USDA considers improvements. The full research brief, “CACFP Family Childcare Home Sponsor Perspectives - Serious Deficiency Challenges,” was published by the Nutrition Policy Institute, University of California, Berkeley, and the CACFP Roundtable. This research is part of a larger project funded by Healthy Eating Research, and national program of the Robert Wood Johnson Foundation.
