July 8, CBC News:
Manitoba’s busy Gimli Beach is under an E. coli advisory following a July 6 test.
An advisory has been posted to warn swimmers at the popular Lake Winnipeg beach.
The acceptable amount is 200 colony-forming units, or CFU, of E. coli per 100 millilitres; this week’s test found 322 CFU.
To reduce the risk of illness, the province is advising swimmers to avoid swallowing water, wash hands after swimming and avoid swimming with an open wound or if you’re sick.
If the water is high, or if there are strong north winds — conditions that may wash bacteria from the sand into the water — people are asked to reconsider taking a dip at all.
A test July 4 showed only 39 CFU per 100 millilitres, well within accepted guidelines.
Meanwhile, an algal bloom more than seven times the acceptable level has resulted in an advisory for Shoal Lake Beach. Read more.
