Story summary

Halton Region Public Health has advised people to stay out of the water at two public beaches, Bronte Beach Park and South Shell Park, as of September 6 at 12 p.m. due to high levels of E. coli bacteria in the water. According to public health guidelines, water is considered unsafe for swimming when one sample contains 400 or more E. coli bacteria per 100 millilitres or the geometric mean of five samples is 200 or more. The presence of high E. coli levels increases the likelihood of other harmful organisms being present in the water, which can cause various illnesses and infections. Consuming E. coli can lead to serious symptoms such as stomach cramps, diarrhea, and vomiting.
