Sonoma County public health officials are urging caution while swimming in or being near the Russian River after tests this week revealed the presence of a harmful toxin produced by blue-green algae near four public beaches.
Officials are not advising people to avoid swimming in the river — at least, not yet. But they are asking people to take precautions, especially with children and pets. Both are more susceptible to being harmed by the toxin.
“I think it would be better not to bring the dog to the river,” Dr. Karen Holbrook, the county’s deputy health officer, said Thursday. “If they do bring a dog, they need to monitor him or her very closely.”
The warning was issued after tests revealed the presence of Anatoxin-a in the water near the four beaches. The naturally occurring toxin attacks the central nervous system of mammals and can be so lethal that it’s earned the scary moniker “VFDF” — short for “Very Fast Death Factor.”
Under new state guidelines, any amount of the toxin found in waterways is enough to trigger health warnings. Officials began putting up signs Thursday at all ten of the Russian River’s public beaches encouraging people to be mindful of the algae and to follow recommendations to minimize risks from exposure.
The suggestions include not ingesting river water or using it for cooking, keeping pets and children away from algae and showering with fresh water after getting out of the river.
