"Deadly Dog-Killing Flatworm Uncovered in Southern California"

UC Riverside scientists have discovered the presence of a potentially fatal dog parasite, Heterobilharzia americana, in a portion of the Colorado River that runs through California. The parasite, previously found mainly in Texas and other Gulf Coast states, can cause canine schistosomiasis, impacting the liver and intestines of dogs. Researchers collected over 2,000 snails from the river banks and confirmed the presence of the parasite. Health officials are urging pet owners to be aware of the risks and to seek veterinary care if their dogs show symptoms after swimming in the Colorado River.
