People and pets are being advised to not swim in two Quispamsis beaches because of the appearance of blue-green algae, also known as cyanobacteria. One provincial park beach in New Brunswick is also closed for swimming because of a high sample of E. coli in the water.
Several swimming spots have been closed in the province due to high E. coli levels and according to a University of Guelph professor, climate change will likely make these occurrences more common.
