Advice for the Backyard Gardener from the Help Desk of the
UC Master Gardener Program of Contra Costa County
Californians who raise poultry outdoors are invited to get their eggs tested for contaminants.
To find out if harmful substances on the ground that are eaten by hens get passed along in the eggs they lay, Maurice Pitesky, UC Cooperative Extension poultry specialist at the UC Davis School of Veterinary Medicine, is providing free egg testing.
"We're trying to understand the connection between the environment that backyard poultry are raised in and the eggs they are producing," Pitesky said.
Pitesky's colleague, veterinary toxicologist Birgit Puschner is testing eggs for different types of contaminants, depending on the county the eggs are from. Eggs from counties recently affected by wildfires will be tested for chemicals, building materials and heavy metals that may have been carried in the smoke and ash. Pitesky and Puschner are also looking for lead and PCBs in eggs from certain regions of the state.
The UC Cooperative Extension poultry specialist will share individual egg results with each poultry owner. At the end of the study, all of the results will be summarized and made available to the general public.
Pitesky describes the project in a video produced by CropMobster for UC Davis School of Veterinary Medicine and UC Agriculture and Natural Resources. You can watch the video at https://youtu.be/3ZlytlUIS3I.
