An outbreak of Escherichia coli closed six beaches in Minneapolis. Health officials said that 69 people had symptoms of bacterial infection. They were all swimming in Lake Nokomis, which is why that lake will be closed by the end of the season.
Minneapolis Department of Health has claimed over 69 people have gotten sick only by swimming in the Lake Nokomis. Fortunately, none of them are in hospital. After discovering that levels of E. coli in that lake exceeded standards allowed by the state, they closed beaches last week.
During this season, four more beaches have been closed because of high levels of the bacteria. The Bde Maka Ska Thomas and 32nd Street beaches will be closed for visitors for another week as well as Lake Hiawatha Beach and the beach at Theodore Wirth Lake. They will be tested on Monday. If the levels of bacteria are within the standard, they will reopen.
The reasons for the officials to close beaches because of this bacteria can be based on daily or monthly tests. On a daily level, the number of E. coli organisms must not exceed 1,260 in 100 ml of water. That is, during a month, the number of organisms in five samples in 100 ml of water can’t be higher than 126.
Officials recommend that ill people stay out of the lakes and advised people not to swallow the water. Also, they should stay out of the water after the rain, when the levels of bacteria are on the rise. The swimming season in Minneapolis will end on September 2, and for now, only six out of 12 beaches are open for swimmers.
