Today wasn’t a great day to be at the beach – not only because of the cool, grey conditions but also because public health units have added some new warnings about bacteria in the water.

Centennial Beach in Barrie is one of several beaches in the region with beach advisories.

“We test for E. coli in the water, so this week the test results for Centennial Beach are elevated,” says Brenda Armstrong with the Simcoe Muskoka District Health Unit.

The City of Barrie collects water samples on behalf of the health unit. Samples are collected weekly.

The health unit wants people to know that swimming when bacteria levels are up comes with a certain amount of risk.

“There is an increased risk of infection so that's particularly important for people who might be more vulnerable or at risk of acquiring an infection,” says Armstrong.

Roger and Shirley Howell are vacationing in Barrie from England. They say they hope people pay attention to the signs and take precaution.

“In general all signs if they're obeyed are a good idea but if people ignore them then they choose to ignore them and that's up to them they take the risk don't they?” the couple says.

While swimming is not recommended, there are a few things bathers can do to be safe if they choose to go in the water.

“If you choose to go in the water it is certainly important (not to ingest) the water, so not putting your head or face in the water and washing your hands thoroughly when you go out of the water as well,” says Armstrong.

Health officials say heavy rain, windy conditions, and even wave action can contribute to elevated bacteria levels. The beach posting will stay in place until water samples show bacteria levels have decreased.

In addition to Centennial there are a number of beaches in Simcoe County and Muskoka that are posted tonight.

Advisories are in effect for:

  • Couchiching Beach, Orillia (since July 23)
  • Barrie Centennial Park, Barrie (since July 22)
  • Port Sydney Beach, Huntsville (since July 22)
  • Port Severn Beach, Georgian Bay (since July 18)               
  • Innisfil Beach Park South, Innisfil (since July 17)
  • Leonard's Beach, Innisfil (since July 17)
  • Earl Rowe Day West Beach, Adjala-Tosorontio (since July 16)
  • Earl Rowe Day Beach, Adjala-Tosorontio (since July 16)

If you choose to swim during an advisory, the health unit says it may be prudent to avoid ducking your head or swallowing the water.
