About Us

Southern Counties DHIA is a non-profit member owned cooperative that was founded in 1973 when Riverside County, San Bernardino County and Los Angeles County DHIA’s merged to form one organization.

The association has a seven member board of directors elected from the membership dairies. Today SCDHIA provides testing service from two locations to dairy farms across Southern and Central California. An office in Chino and office/laboratory in Shafter California allow timely service across a large geographical area.

The facility in Shafter has a milk analysis and feed analysis laboratory. All samples for both milk and feed are analyzed at this location.
