Health New Zealand has issued a health warning after consecutive water samples revealed high levels of faecal bacteria in the Selwyn River at Glentunnel and Whitecliffs.
Public Health Specialist Dr Claire Salter said recent rainfall in the area likely caused the contamination.
“Rainfall in the last few days has most likely led to these high levels of faecal bacteria,” Dr Salter said. “Many other popular swimming sites in Canterbury may also be affected after recent rainfall. People should avoid all rivers and beaches for at least two days after heavy rain.”
Dr Salter warned that the water quality at these sites is unsafe for recreational use, including swimming, due to health risks posed by bacteria and other pathogens.
“Eating shellfish from these sites should also be avoided. If fish are consumed, ensure the gut and liver are removed and wash them thoroughly in clean water before cooking,” she said.
Contaminated water may contain disease-causing microorganisms such as viruses, bacteria, and protozoa. While most health effects from exposure are minor and short-lived, more serious illnesses such as Hepatitis A or Salmonella infection are possible.
Environment Canterbury has listed the affected sites on its website. Residents are advised to check water quality information before swimming or gathering seafood.
