Harmful Algae Blooms

The Bureau of Environmental and Occupational Health (BEOH) in the Wisconsin Division of Public Health is working with the Centers for Disease Control and Prevention (CDC) to collect information about human and animal illness and death resulting from exposure to blue-green algae (also known as cyanobacteria). By studying this information, BEOH staff will be able to better understand and quantify the public health problem posed by harmful algal blooms (HABs), raise awareness of these problems, and inform efforts to prevent exposures from occurring.

The HABs program is partnering with the Wisconsin Association of Lakes to collect case information about human and animal illnesses or deaths. BEOH staff are asking members of local lakes associations to notify them of any known or suspected human or animal exposures to cyanobacteria that may have resulted in illness or death. Animal exposures can include pets, livestock or wildlife such as birds and fish.

The HABs team will be collecting information about symptoms and any treatment received or provided. They will also collect exposure information, and may seek to quickly collect environmental samples. While individuals experiencing symptoms of cyanobacterial exposure should seek medical attention, general information and referral on health issues related to harmful algal blooms is available from BEOH staff.

Cases can be reported by calling (608)266-1120 or by visiting www.Tinyurl.com/bluegreenalgae and leaving your contact information. This will generate an email to HABS team members who will then follow up with you. For more information about harmful algal blooms or the HABs program, contact Dr. Mark Werner at (608) 266-7480.
