A suspected bloom of potentially toxic blue-green algae has been reported in the Leeds & Liverpool Canal. Although blue-green algae occur naturally in freshwater, there is a risk of serious hazard to health when they occur in high concentrations. The highest concentrations of blue green algae toxins are found in scum which can form on the water surface, and which can look like turquoise paint, grass clippings or floating mats. The toxins can affect humans, pets and livestock. You should avoid all contact with water which has a blue-green paint-like scum on its surface and also avoid contact with very green water.
Immersion sports (such as paddling, swimming, and canoeing) carry a higher risk to human health and should not be practiced where there is a scum or green water present. Such conditions can come and go quickly, which means that British Waterways cannot guarantee the suitability of the water for these activities. Therefore, it is your responsibility to check for scum or green water prior to any immersion activity. Do not allow pets or livestock to swim in or drink the water. We recommend that you keep dogs on leads.
If you do come into contact with the algal scum, remove contaminated clothing and wash all exposed skin in clean water as soon as possible, particularly before eating or drinking.
If you are in any doubt about your welfare after contact with the algae, please seek medical advice.
This algal bloom has not yet been sited in the S & DAA stretch of the Rufford branch of the canal but if seen, please report to the S & DAA Secretary on 01704 213690.
