Blue green algae confirmed at Mullinger Swamp

News release
14 February 2019

A recent suspected algal bloom at Mullinger Swamp has been confirmed as blue green algae.

Natural Resources South East Team Leader Public Lands Brian Robins said test results from a water sample taken from the swamp have confirmed a high concentration of blue green algae.

“The algal bloom is a result of a number of factors including higher temperatures, low water flow, sunlight and nutrients present in the swamp,” Brian said.

Warning signs have been installed at the site, and the Department for Environment and Water is warning the public to avoid any direct contact with the affected water.

“Contact with blue green algae can cause reactions like itchiness, rash and sore eyes.”

“If swallowed, it can also cause gastroenteritis, nausea or vomiting. So also avoid eating any fish, shellfish or crustaceans such as yabbies from the area.”

“We urge you to keep dogs and other pets away from the water as well, as they are highly susceptible to serious illness.”

If you do come in contact with contaminated water, wash immediately with fresh water and seek medical attention if experiencing illness.

The Department for Environment and Water together with Parks Victoria will continue to monitor conditions and will remove signage once the water is safe.
