Concern after dog-killing flatworm found in California for first time – in Colorado River
A dog-killing parasite that was believed to only exist in Texas and other Gulf Coast states has been discovered as far west as California for the first time, scientists have warned. Experts at the University of California Riverside found the Heterobilharzia americana parasite, a flatworm commonly known as a liver fluke, in spots along the Colorado River where it runs through Southern California. According to the university, the flatworm has never before been seen outside of Texas and surrounding areas, and other studies have found most infections occur in Texas and Louisiana, though some have occurred in North Carolina, Texas, and Kansas.
