Swimmers and fishers have been reassured that they have nothing to fear from the water in Spencer and St Vincent gulfs in the wake of mass fish and dolphin deaths off the state's coastline.
SA Health told The Advertiser algal blooms, found across the state's coastline most likely due to March's prolonged hot weather and heavy winds, did not affect human health in any way.
"Consumption of fish caught alive do not represent health concerns, however SA Health advises fish caught dead should not be eaten due to concerns over decomposition and spoilage," a spokeswoman said yesterday.
The assurance comes as a taskforce of experts today start testing water to help solve the mystery of the thousands of dead fish and 16 dead dolphins.
The Fisheries Department, Environmental Protection Authority and SA Water will lead the taskforce, which will also conduct tests on the fish and some of the dolphins.
Several other nations around the world have also experienced unexplained mass sea deaths in recent months.
