Toxic algae blooms in Bridgend.
A TOXIC blue-green algae has been confirmed in Bridgend.
Cyanobacteria, also known as blue-green algae, is a microscopic bacteria found in freshwater ponds, lakes, streams and brackish water ecosystems.
Despite being a natural summertime occurrence, the algae can produce toxins that are dangerous to humans, dogs, cattle and horses.
Bridgend Council confirmed last week that blue-green algae has now developed in water near Tremains Wood, Brackla.
People have been asked to report any further sightings to the council or Natural Resources Wales.
Posting on Twitter, the council said: "Due to the heatwave, bluegreen algae has now developed in water near Tremains Wood, Brackla.
"It can produce toxins harmful for humans and dogs so please steer clear."
Blooms in the algae can produce several toxins which can cause skin rashes, nausea, vomiting, stomach pains, fever, headaches - and even liver and brain damage.
Water affected by the algae appears green, blue-green or greenish-brown and can produce musty, earthy or grassy odours.
