Ahmed El-Moghazy joined UC Agriculture and Natural Resources as a UC Cooperative Extension food safety specialist in February and is based at UC Riverside. Food safety, according to El-Moghazy, are measures that ensure food is free from harmful contaminants, prevent foodborne illnesses and is safe to eat. El-Moghazy is responsible for assisting California farmers and food processing facilities to enhance food safety practices by training appropriate personnel and addressing food-safety issues on their farms.
As the principal investigator for the 2-SAFE Lab at UC Riverside, El-Moghazy is investigating the accuracy and applicability of point-of-use biosensor technology. The small, lightweight and easy-to-use sensor can be used while out in the field or in a packing house to test contamination of liquids such as irrigation and washing water or solids like food samples.
Testing for foodborne pathogens traditionally takes two to three days and the process can be costly. The biosensor technology that El-Moghazy is using is inexpensive and can provide results within one work shift, which allows businesses that grow fresh produce to confirm the safety of their products before sending them to the market.
The alternative, selling contaminated food to consumers, is not only detrimental to human health, but can ruin the reputation of businesses, making way for unanticipated costs associated with recalling contaminated products and regulatory consequences including fines and sanctions.
El-Moghazy is also developing the next generation of antimicrobial surface coatings and materials that can rapidly control the foodborne pathogens and hinder the transfer of harmful bacteria from contaminated food to non-contaminated food.
El-Moghazy is optimistic that his research can safeguard public health, reduce the burden of foodborne illness and protect the integrity of businesses. Although El-Moghazy serves the entire state, he is dedicating a large part of his needs assessment and efforts in Southern California where high-value specialty crops such as avocados and citrus are grown.
"Did you know that one in every six Americans get sick from eating food contaminated with a foodborne pathogen?" asked El-Moghazy. Understanding the fatality of foodborne illnesses, El-Moghazy believes that increasing awareness through education is an essential aspect of his role. "It's true, but not many people realize this, or that 40% of foodborne illnesses stem from fresh produce."
To protect consumers, the U.S. Food and Drug Administration requires farms with a certain level of annual sales (adjusted for inflation) of fruits and vegetables typically consumed raw to have one employee who has completed an FDA-approved Produce Safety Rule Grower Training.
In addition to certified trainings, El-Moghazy offers technical assistance to ensure growers comply before and after inspections, as well as resources for several topics including produce safety, agriculture water, flooding, soil amendments, worker health, hygiene and training and postharvest handling and sanitation. He can also assist in developing food-safety plans and other general farm food-safety protocols. His technical expertise covers all aspects of food production and supply including irrigation water quality, hygiene of harvesting tools and transportation.
Before joining ANR, El-Moghazy completed two years as a visiting scholar in the UC Davis Biological and Agricultural Engineering department before continuing as a postdoctoral fellow in the UC Davis Food Science and Technology department for 5 years. Much of his work was rooted in the development of biosensors and antimicrobial materials for food safety. While in Davis, he collaborated with local farms and food processing companies on food safety research and extension.
El-Moghazy earned a Ph.D. studying developmental biosensors for food safety applications to detect pesticides residues from a joint program offered by University of Perpignan in France and Alexandria University in Egypt. He also earned a master's degree in developmental biobased fungicides and a bachelor's in agriculture science from Alexandria University. Finally, he completed a fellowship at the Institute of Plant Protection, Szent Istvan University in Hungary, where he studied how to extend shelf-life of fresh produce using biomaterials.
El-Moghazy is based at UC Riverside in the Department of Microbiology and Plant Pathology. He can be reached at aelmogha@ucr.edu or (951) 827-0257.

Indoor food waste bins (also known as kitchen bins or compost bins) have become a popular addition to Californian homes. They are a great way to collect food scraps and divert food waste from landfills, but they can sometimes attract pest insects like maggots, ants, and fruit flies. Below are some tips for keeping a pest-free food waste bin:
- Empty and clean indoor food waste bins frequently. Dump the food waste into your outdoor compost pile, drop it off at a composting facility, or place it into your municipal green waste bin. Emptying your indoor bin frequently (even if it's not full) can make it less attractive to pests and prevent flies from developing inside. Once empty, rinse the bin and clean it with soap and water before putting it back on the counter. Be sure to check the bin for any fly maggots or pupae stuck to the sides; scrape them off if found.
- Keep your bin or food scraps in the freezer. Putting your food waste in the freezer prevents it from breaking down and smelling. It can also kill any pest insects and prevents them from infesting your food waste bin.
- Place food scraps in a paper bag, wrap in newspaper, or use a compostable bag before placing in your organics or green waste bin for collection. Don't use a regular plastic bag since these are not biodegradable. This can keep the inside of your bins cleaner, but also reduce moisture which maggots need to survive. Excess moisture can also make your bin smell.
- Choose a bin with a tight-fitting lid. Prevent pests from being able to get into the bin by choosing a food waste bin with a secure lid. If your bin has ventilation holes at the top, choose an appropriately sized charcoal filter to cover the openings. Inspect the filter frequently for any fly maggots or pupae.

Agriculture generates $59 billion and employs nearly 400,000 individuals in California. The industry, however, is often threatened by challenges like climate change, land conversion and water scarcity. Motivated to act, Sustain Southern California – an organization associated with UC Irvine Beall Applied Innovation – hosted a roundtable discussion on Feb. 20 featuring subject matter experts including Darren Haver, director of UC Agriculture and Natural Resources' Research and Extension Center System.
During his keynote address, Jose Arriaga, Orange County Agricultural Commissioner, defined sustainability as food and fiber production that does not compromise the ability for future generations to meet their needs. In doing so, he acknowledged the benefit of discussing such timely topics with key players, especially for places where agriculture is not as prevalent as it used to be.
“Many people don't think of Orange County as a place for agriculture. It's probably because less land is being reserved for agriculture, not like back in the day. And that worries me,” said Arriaga.
The first roundtable discussion centered on sustainable agriculture, with Haver participating alongside other industry leaders based in Southern California, including A.G. Kawamura of Orange County Produce, Steve Brazeel of Sunterra Produce and Elevated Foods, Anthony Curci of Buttonwood Ranch and Parker Cohn from Performance Resource Management.
In discussing today's generation, Haver said that he has seen a shift over the last few decades away from yield alone, which used to be the most important aspect of production in agriculture. Today, much more attention is dedicated to sustainability – a change that Haver attributes to the younger generation of researchers and plant scientists working in agriculture.
There has also been an emphasis on sustaining the environment while maintaining economic progress. Haver recognized these important elements, but highlighted the social impact of sustainability, too.
“I don't have all the answers, but I do believe that addressing the environmental, economic and social aspects of agriculture is important. I also think that these factors should be addressed systemically rather than in silos,” said Haver.
Southern California agricultural producers, in particular, are responsible for $7.8 billion in gross receipts and nearly 100,000 jobs directly related to agriculture. In Orange County alone, where Haver is based at the South Coast Research and Extension Center, agriculture makes up $86 million of total economic output, with nurseries leading as a top commodity followed by fruit trees, vegetable production and livestock and apiary.

Inside a quiet classroom, Sadie, a 4-H member in Orange County, stands in front of two judges with an insulated cooler bag in hand. From it she pulls out plates, utensils and napkins and sets them down on the table. She unzips the bottom compartment and carefully reaches for a cast iron platter with golden fluffy pancakes piled on top.
“Would you like syrup with your pancakes? I highly recommend it,” said Sadie, an eighth grader who is participating in the annual 4-H Food Fiesta for a second time.
4-H, a youth development program supported by the University of California Agriculture and Natural Resources and administered through local UC Cooperative Extension offices, promotes hands-on experiential learning for all youth.
Rita Jakel, 4-H program coordinator for Orange County, described the Food Fiesta event – intended for ages 5 to 18 – as an opportunity to practice and showcase public speaking skills through a fun, food-related competition.
Youth present their creations before a panel of evaluators, who ask them to describe how they prepared the dish and why, and how they managed challenges throughout the process. The interaction between youth and adult leaders provides a unique opportunity for youth to practice career readiness skills such as job interviews and public speaking.
This year's theme was “Super Carbolicious” and 4-H participants were encouraged to make their favorite dishes using ingredients like pasta, potatoes and bread. Carbohydrates are often perceived as unhealthy, which is not a helpful mindset to have when teaching youth about nutrition. Carbohydrates provide the body with glucose, which is converted into energy that people need to function throughout the day.
Some of the dishes that were presented during the Food Fiesta included chocolate chip banana bread, cheesy baked potatoes, cookies and Nutella-stuffed crepes. 4-H member Kaitlin had only ever attended the Food Fiesta to cheer on a friend. This year, she decided to participate and presented pumpkin macaroni and cheese as her entry.
“Pumpkin mac and cheese is better than the regular one because there's a lot more flavor and you have to use two cheeses: cheddar and parmesan,” explained Kaitlin, a seventh grader. When asked what motivated her to participate instead of a being a bystander this time around, Kaitlin said that she wanted to work on her presentation skills.
“Usually, I'm a bit shy and I don't like to share that much. The Food Fiesta helped me practice speaking up more so that I can accomplish my goals,” Kaitlin said.
Sadie, who loves public speaking, admits that it wasn't always a strength of hers. “There was a time when I hated public speaking. But when I joined 4-H's cake decorating, poultry and food fiesta events, I got more comfortable with public speaking,” she said. “Now, I like going to events and showing off. I get to show off turkeys, my cakes and, today, I presented homemade pancakes.”
Helping to keep the day's festivities running smoothly were two 4-H state ambassadors: Michaela and Laurelyn, two high school seniors. Both have been involved in 4-H for over nine years, with Laurelyn being a third-generation 4-H member. “My grandmother grew up in a 4-H club in Orange County. She still raises breeding lambs for 4-H members to this day,” said Laurelyn, whose mother was a 4-H member in San Joaquin County.
As state ambassadors, they are responsible for creating and presenting workshops during state, national and regional events. “We also engage the public via social media, specifically TikTok and Instagram (@4horangeco),” said Michaela, who is in her second year as an ambassador.
During the Food Fiesta, Michaela and Laurelyn made themselves available to answer questions from participants and their families. Both ambassadors agreed that seeing parents involved in 4-H should not come as a surprise. “Being in 4-H is a family effort. This isn't an extra-curricular where you just drop your kids off and leave,” said Michaela.
Laurelyn shared that the biggest misconception others have about 4-H is that they think it's about introducing youth to agriculture or livestock. There's a civic engagement and leadership component to it, too. “If parents knew about all the ways 4-H can benefit their kids, I think more people would want to join us,” she said. “And they're finding fun ways to help us learn life skills, like this Food Fiesta.”
The homemade dishes weren't the only thing to look forward to, however. In another building, Sandy Jacobs, volunteer event coordinator, and her team set up a kitchen quiz for members. On several tables, there were different cooking tools and participants were challenged to name as many tools as they could.
In another classroom, while some members were presenting food, others presented their themed table setting décor. Participants had to prepare a complete table setting entry including a menu card, centerpiece and table settings for two. Judges considered creativity, use of color, table setting etiquette, knowledge in talking to the judges, and appearance in their evaluation.
Finally, to wrap up the day, members competed in a cupcake decorating competition. Participants were responsible for bringing their own supplies including tools and edible decorations for Cupcake Wars. Depending on their age group, participants had 20 minutes to decorate two to four cupcakes, each of a different theme.

Valley Oak (Querus lobata):
The acorns were a staple food, which was leached (rinsed with water) to remove the bitterness, and ground into flour with mortar and pestles. The ground acorns were used in stews/soups, pancakes/tortillas, mush, or layered into pits and cooked with other plants and meats. Oak galls were squeezed to make a blue-black ink for tattoos and tannins were used to make dyes and decorate animal skins.
Deer Grass (Muhlenbergia rigens):
A major grass for creating beautiful, sometimes water-tight baskets to cook food, to carry and store food and other items. Stalks were generally harvested in the spring when easy to pick, then wrapped to keep straight and allowed to cure for a year. They were often soaked prior to weaving into basket. About 1600 stalks would be needed to make one basket.
One of the most beautiful California grasses, this easy-to-grow plant attracts butterflies in the spring with its cream-colored flowers and seed-eating birds in the summer.
Santa Barbara Sedge (Carex barbarae):
The rhizomes (underground stems which generally grow horizontally) provided the strongest threads for basket making. The people would manage the rhizome growth by cleaning the soil of anything that might obstruct the growth (i.e., rocks) to allow the rhizomes to grow long and straight. An evergreen grass, the summer flowers range from cream, red and purple colors, which attract butterflies.
Toyon, aka California Holly (Heteromeles arbutifolia):
The wood from this sturdy shrub had many uses including tools, games/toys, fuel for smoking fish, and religious ceremonies. The red berries produced in the fall which were eaten after roasting over coals or dried in the sun.
An evergreen shrub, the summer white flowers attract bees and butterflies. Birds love the berries.
Blue Elderberry (Sambucus cerulea):
This tough, easy-to-grow shrub or tree is dormant in the winter. The spring and summer blooming cream or yellow flowers attract bees and butterflies, with their berries being an important food source to many birds.
Manzanita (Arctostaphylos manzanita):
Its distinctive red wood which was sometimes used to dry and smoke fish. The fruit was gathered in summer, then dried and ground to make coarse meal which would be mixed with a little water during winter months or made biscuits. They would make tea with the berries and tips of the branches, which apparently was a pleasant drink.
Sticky Monkey Flower (Mimulus aurantiacus):
The seeds were used as a food source. They were gathered, parched, ground, and added to foods or eaten by the handful. Flowers were used as décor after drying, made into wreaths, and used in religious ceremonies. The roots and leaves were used for medicinal purposes.
This drought-tolerant, evergreen shrub blooms in the spring, summer, and fall. The bright yellow tubular flowers attract hummingbirds, bees, and butterflies. Autumn seeds attract small birds.
Whenever I see any of these California native plants, I think of how the indigenous people of California used these plants over thousands of years. By growing them in our gardens, we honor that history, help the survival of these plants which provide food sources for so many birds, bees, and butterflies, reduce water usage, bring variety to our gardens, and joy to our spirits with their beauty.
