Health New Zealand has issued a warning for potentially toxic algae in parts of the Selwyn River.
Moderate to high cover of benthic cyanobacteria has been found in Waikirikiri/Selwyn River at Glentunnel and Whitecliffs Roads.
Health NZ said people should avoid the areas and animals should not be allowed near the river until the health warning was lifted.
Other areas of the river could also be affected and people are advised to be cautious of every low-flowing river.
Medical Officer of Health Dr Annabel Begg said the algae looked like dark brown or black mats and could produce toxins harmful to people and animals, especially dogs.
“Exposure may cause skin rashes, nausea, stomach cramps, tingling and numbness around the mouth and fingertips,” she said.
“If you experience any of these symptoms, seek medical advice urgently and let your healthcare provider know you’ve had contact with dark brown/black algal mats or water in this area.”
Environment Canterbury monitored the sites during summer and would advise the public of any changes to water quality.
