Handling of Fruits and Vegetables After Harvest for Small Farms

An online video program to educate small farm managers and staff about handling of fresh fruit and vegetables after harvest for improved quality and reduced food loss.

Innovative produce storage research

In today’s world, food safety and quality is of outmost importance. In some produce like corn and rice, which are dried before storage, high commodity moisture contents at harvest and high relative humidity storage conditions enable growth of fungi that produce highly toxic compounds (e.g., aflatoxin). Currently, over 4.5 billion people are chronically exposed to aflatoxin in their foods that cause liver cancer and other health problems. At UC Davis, Dr. Irwin Donis-Gonzalez, and his team are focused on engineering practical solutions to ensure food safety and quality for all parts of the world. One of our current projects is evaluating the use of hygroscopic salts and drying beads to keep produce dry and free of moisture, ensuring a safe and practical method of storing dry produce, like corn. For over 100 years, the UC Davis Department of Biological and Agricultural Engineering has been utilizing our world renowned faculty and ingenious students to solve the worlds food safety challenges. 

Harvest & Postharvest Handling Systems

Details regarding common handling practices employed during the harvest, cooling and postharvest handling of various horticultural crops.

Postharvest Handling and Nutrition

Postharvest Handling to Maintain Quality of Fresh Produce (Dr. Marita Cantwell 2013) This series of 4 videos was created in support of the WIC program, a federally-funded health and nutritional program targeting women, infants and children. The presenter is Dr. Marita Cantwell, Vegetable Specialist, UC Cooperative Extension, Dept. of Plant Sciences, UC Davis. This project was funded by the California Dept. of Food & Agriculture. 

Produce Food Safety (Sprouts)

Safer Processing of Sprouts
The California Department of Public Health, Food and Drug Branch and the U.S. Food and Drug Administration Center for Food Safety and Applied Nutrition jointly developed this video in cooperation with the Centers for Disease Control & Prevention, university researchers, and industry representatives to assist the industry in producing a safer product. The video may also be useful for retailers, regulators, and anyone working with the industry that wants to better understand the product and current recommendations for best production. (2000)
Topics covered in the videos:

Produce Food Safety (Cantaloupe)

With Consumers in Mind: Growing, Handling & Shipping CA Cantaloupes (Dr. Trevor Suslow, 2005)
Developed by Dr. Trevor Suslow at UC Davis, under funding from USDA CSREES and the CA Cantaloupe Advisory Board, and in collaboration with the California Melon Research Board this video provides general background and aspects of interest to foodservice buyers and retailers, detailing cantaloupe shed and field packing, California environmental conditions where melons are grown, scientific studies on cantaloupe safety, worker hygiene best practices, equipment sanitation best practices and shed packing best practices.

 
 

Good Agricultural Practices (GAP) Guidlines for the California Cantaloupe Industry (Dr. Trevor Suslow, 2005) Developed by Dr. Trevor Suslow at UC Davis, under funding from USDA CSREES and the CA Cantaloupe Advisory Board, and in collaboration with the California Melon Research Board this video is directed at the growers and primary supplies of cantaloupe, detailing Good Agricultural Practices during the production, handling and postharvest handling of California grown cantaloupe. Issues addressed in the video include safe water use, safe soil amendment application and how to reduce the potential for microbial contamination. The video also provides recommendations regarding food safety best practices for worker training, field and harvest sanitation, postharvest packing house operations, shed packing operations and transportation to markets.
