Employee Comment: Presidential Policy Seismic Safety

The University of California Office of the President invites comments on a proposed Presidential Policy Seismic Safety. The policy is proposed to be revised and includes the following key issues:

• Replace the 2030 deadline with a continual improvement requirement for each location to achieve a minimum 4% per year reduction of non-compliant space above the established 2022 baseline square footage averaged over a three-year period. Note that any improvements completed in compliance with state-mandated requirements for critical care facilities will count towards the 4% reduction goal.

• All currently occupied Seismic Performance Rating VI facilities, shall be given the highest priority in capital planning and allocation decisions and brought into compliance with policy no later than Dec. 31, 2037.

• Existing leases for certain non-compliant UC-occupied facilities may be extended through 2037.

The proposed revisions are posted here: https://ucanr.edu/sites/PCPA/Revisions/.

If you have any questions or if you wish to comment on this policy revision, please contact Robin Sanchez at rgsanchez@ucanr.edu, no later than Nov. 1, 2024. Please indicate “Seismic Safety Policy” in the subject line.

UC food-safety specialist tests biosensors to ensure safe produce

 

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.

Chris Jakober named Risk and Safety Director

Chris Jakober has joined UC ANR as Director of Risk & Safety Services. In this role, Chris will lead ANR's programs and teams for Environmental Health & Safety and Risk Management, reporting to Director of Facilities Planning and Management Brian Oatman.

Chris completed his bachelor's degree in chemistry at Oklahoma State University, where he studied land application of wastewater treatment residuals for nitrogen and phosphorus runoff mitigation and an in-vitro procedure to determine bioavailability of heavy metals from ingestion of contaminated soils. In 2001, further educational pursuits brought him to California, where he completed his doctoral work at UC Davis in agricultural and environmental chemistry, measuring carbonyls in motor vehicle exhaust.

His professional experiences include air-quality consulting on novel dust mitigation at Owens Lake for Los Angeles Department of Water and Power, air quality research for the California Air Resources Board (e.g. regulating ozone emissions from indoor air cleaners, area source greenhouse-gas emissions verification, and health exposure risk assessment for environmental justice communities), and environmental health and safety in support of research at UC Davis.

Home Landscaping for Fire Safety

Living with the threat of wildfire is an unfortunate fact of life for Californians. While we cannot control wildfire, we can help minimize its destruction by practicing fire safe strategies which harden the landscape by reducing the vulnerability of your home and property to wildfire.
In recent years, we have seen many fires that have affected homes that are not even close to an open space. A single spark which is called a firebrand or flying ember can travel miles in the wind making us all vulnerable.

Hardening the landscape
Creating a beautiful and functional landscape as well as a fire adapted property can be accomplished using the concept of Defensible Zones. Your property can be viewed as 3 defensible zones and when done properly, it makes your home and property less prone to fire. In these zones, we look for places to prevent ignition, slow fire down, and improve firefighter access.

The Zones are:
Zone 0: Ignition Zone
0-5 feet from home.
Zone 1: Firebreak Zone
5-30 feet from home.
Zone 2: Reduced Fuel Zone
30-100 feet from home or to your property line.

Zone 0: Ignition Zone: 0–5 feet
This zone is the most important one. The first 5 feet from your home are critical to the safety of your home and family. Those 5 feet should be clear of anything that will burn. This includes plants, shrubs, overhanging trees, and mulch. Remove all flammable hazards that are within this critical zone including stacks of wood, propane tanks, wooden chairs, benches, dead vegetation, leaves or cobwebs under the eaves or in rain gutters, and wooden fences. It is important to eliminate any material that could be ignited by a flying ember. Also make sure to remove tree branches that overhang the roof.

Zone 1: Firebreak Zone: 5–30 feet
In this zone, the primary goal is to stop a fire from spreading. We want to use space (separation) to create areas that “break” or slow the path of any fire. Hedges and wooden fences are of special concern, as they can channel flames toward the house. Strategically created space between shrubs, trees, plants, and anything else that might burn will create a fuel break that will make it harder for flames to spread on the ground from plant to plant and to your home. Prune and thin, remove plants and separate layers of vegetation, for example by removing lower tree branches, so that a fire cannot “ladder”, or climb up shrubs to trees to your home/roof. Incorporate fire-safe hardscape materials throughout this area like stone, gravel, cement, metal fences, water features and pathways.

Zone 2: Reduced Fuel Zone 30–100 feet
We want to REDUCE THE FUEL in this zone all the way around your home. Fuel is anything that will burn including dead vegetation, downed branches, overgrown areas, low hanging trees, flammable plants and wooden fencing. Keeping this area clear of dead material and adding hardscape will eliminate fuel and help stop fire from spreading across your property. It will also help improve firefighter access to your property.

How to Start: Develop a Strategy for each zone
• Identify problem areas
• Minimize slope risk
• Target plants for removal
• Add plants that are fire resistant
• Plant in an island format
• Make liberal use of hardscaping (rocks, cement, gravel, rock walls, boulders, etc.)
• Include irrigation to keep plants and trees from becoming unsafe

Slope:
In a hilly area, fire will travel faster and flames will shoot higher, therefore it is important to add 10 feet of additional space between trees for every 10% increase in slope. This additional space can help keep the fire from laddering from tree to tree up the hill.

Use Fire Resistant Plants:
The most important thing is to plant the right plant in the right place. This maxim is true for growing conditions and also for fire safety. Remember that all plants can burn so placement is the most important factor. Fire resistant plants share the following characteristics:
Leaves: High moisture content, fleshy and large or coarse like you see in succulents and cactus.
Trees: Deciduous: their thin moist leaves shrivel up when there is fire or extreme heat so don't help ladder into the canopy. Also look for trees and shrubs that have an open and airy structure, allowing for more air circulation and are less likely to harbor dead organic material at the center. Drought tolerant or native to California are the best options.

Remove Flammable Plants and Weeds
Here are good clues for identifying Fire PRONE plants:
Leaves: low moisture content/dry, small, fine or needle like cypress and juniper
Oils: Aromatic, resinous like rosemary and eucalyptus. Decorative hedges and large plants, such as bamboo and conifers including cedars and firs.
Trees: plants that produce a lot of debris increase fire danger. Eucalyptus trees have bark that is loose or papery which creates a lot of debris making these trees very dangerous.
Weeds: All weeds that are higher than 3” are highly flammable and need to be removed.

Mulch:
Mulch plays an important role in your landscapes. Besides looking great it provides many benefits:
• water retention,
• soil temperature control
• weed inhibition
• helps prevent soil erosion
BUT…mulch can be highly combustible material in your landscape. The bigger and heavier the pieces the better. But remember it all burns. It is important NOT to have any flammable mulch within 5 feet of your house and other structures.

Maintenance: The final element in a fire safe landscape
Be diligent in your maintenance habits in order to keep your property firesafe as follows:
Ongoing:
• Remove weeds, dead plants, leaves and branches.
• Remove vines from trees and fences.
• Compost or remove all debris.
Annually:
• Thin vegetation and cut weeds to 3.”
• Cut back woody plants.
• Ensure sufficient space between shrubs, house and trees.
Every few years:
• Cut back vines, groundcovers.
• Prune tree branches to 10' above ground and above roof.

Community resources: Firewise: National Fire Protection Association
Firewise is a nationally recognized program for bringing homeowners together to improve the safety of the neighborhood. They offer guidelines, training, and certification.
