Orlando officials warned Tuesday afternoon that people should avoid contact with the western portion of Lake Ivanhoe in College Park where high levels of fecal coliform bacteria were found.
The city’s alert states the cause of the contamination is “undetermined at this time.”
Fecal coliform bacteria comes from the intestines of animals and people. Some types may make people sick, and high levels may indicate that harmful pathogens are present.
Warning signs will be posted around the contaminated portion of Lake Ivanhoe and a canal leading to the rest of lake, which straddles Interstate 4.
City officials will continue testing the lake and announce when bacteria levels are no longer a concern. Updates will be at www.cityoforlando.net/lakealert and 407-246-2220.
