The Northwestern Health Unit has issued swimming advisories at two beaches in the Rainy River district.
Warning signs were posted at Emo beach and Rainy River beach late yesterday after higher than expected levels of E-coli bacteria were discovered during routine water testing.
High e-coli levels can pose a number of health issues for swimmers, including skin, eye, nose and throat infections and gastrointestinal illness.
The advisories will remain in effect until further testing reveals more satisfactory results.
