GRANTS PASS, Ore. -

Because a five-year federal grant has expired, the Oregon Health Authority will be paying less attention to toxic algae blooms in rivers and lakes.

Environmental toxicologist David Farrer says his agency will continue issuing toxic algae warnings, but will have fewer resources to keep track of water samples and do public education.

The funding that expired last month amounted to about $150,000 a year, which covered two employees, travel and materials.

The Centers for Disease Control and Prevention says grants went to nine states to help gather data for a national database on harmful algae blooms.

Experts say there are more toxic algae blooms worldwide. They blame that on warmer temperatures and more pollutants running off the land.

Oregon posted public health warnings for nine toxic algae blooms this year.
