UC Cooperative Extension in San Mateo/San Francisco Counties has joined #GivingTuesday, a global day of giving that harnesses the collective power of individuals to celebrate generosity worldwide.  #Giving Tuesday is held annually on the Tuesday after Thanksgiving, Black Friday and Cyber Monday.  Please kick off the holiday season by supporting the UC Master Food Preservers!

The UC Master Preserver (MFP) Program began in San Mateo/San Francisco Counties in 2014.  In just 3 years our volunteers have interacted with over 5,000 individuals interested in learning how to safely preserve food at home.  Through fairs and festivals, hands-on workshops and library talks, our small group of 28 volunteers teach water bath, steam and pressure canning, pickling and fermenting, dehydrating and freezing, smoking and sausage making, in addition to all kinds of jams and jellies. 

MFP volunteers work with:

  • Home gardeners interested in preserving their backyard harvest
  • Food banks interested in helping their clients safely store and preserve fresh foods and prevent hunger
  • 4-H youth learning the art and science of food preservation for the first time
  • Experienced canners wanting to to bring their canning practices and favorite family recipes up to date 
  • Entrepreneurs wanting to start their own cottage foods business
  • Individuals interested in the health benefits of fermented foods, low-sugar jams, and low-salt pickles.


To stay up-to-date with the most reliable information about food safety and food preservation practices, MFP  volunteers undergo 50 hours of initial training and then an additional 12 hours/year of continuing education each year.   The connection between our volunteers and UC researchers and scientists make this program a valuable resource to our community. 

As this program grows in San Mateo/San Francisco counties, the volunteers are looking to expand their work with underserved communities as well as address the issue of food waste through preserving. Your donation can help make that happen. 



A $50 gift will provide an award for a family entry in the San Mateo County Fair preserved foods category to encourage families to try food preservation at home.


A $100 gift will purchase a water bath canner and basic canning equipment for a local food pantry or resource center to allow their clients to preserve excess produce and avoid food waste.


A $300 gift will provide a scholarship for Master Food Preserver training to an individual who would like to become a volunteer.
