Following samples taken earlier today, Natural Resources Wales have identified blue-green algae in the water at North Dock, Llanelli.
As a precaution, we have installed warning signs asking people and their animals not to enter the water.
Please ensure you and your pets do not come into contact with the algae or the water, and make sure you maintain basic hand hygiene.
Blue-green algae naturally occurs in inland waters, estuaries and the sea. Blooms can form when their numbers become excessive.
Bloom and scum-forming blue-green algae can produce toxins. These toxins can be very dangerous to animals. In humans, they can cause rashes after skin contact and illnesses if swallowed.
