State Sen. Melissa Hurtado (D-Sanger) is frustrated by the lack of wastewater monitoring for H5N1 bird flu in the state’s most at risk communities: regions of the Central Valley where dairy workers, dairy herds and commercial poultry operations are most concentrated. On Tuesday, she introduced a bill to fix that. Called the Wastewater Surveillance Act, if passed, it would require at least one wastewater monitoring site in every California county. The bill would require the state’s department of public health to expand its current wastewater network, known as Cal-SuWers, to include all counties “and prioritize underserved and high-risk areas.”
