The Michigan Department of Natural Resources (DNR) confirmed on August 12, 2014 that about 24 mallard ducks died from type C avian botulism along the southern shore of East Grand Traverse Bay. The ducks were found in a localized, small area near the Acme Township/East Bay Township shoreline in Grand Traverse County. Michigan Sea Grant Extension Educator based in northwest Michigan, Mark Breederland, put together the following article to address avian botulism in the Great Lakes.
What is Avian Botulism and Should we be Concerned?
Avian botulism is a food poisoning whereby waterfowl ingest a toxin which is produced by the naturally occurring rod-shaped bacterium Clostridium botulinum. Typically, these native bacteria live in a highly resistant spore stage and are of no impact to fish and wildlife; however, under the right circumstances (usually anaerobic conditions), the bacteria will germinate, produce and make bio-available one of nature’s most potent toxicants. The toxin causes muscular paralysis. Often the birds are unable to hold their head up and may drown or die from respiratory failure. Avian botulism is also known as limberneck, due to the bird’s inability to hold up its head.
While small invertebrates (often maggots) are not impacted by the toxin, they often serve to pass the toxin up the food chain. A rotting carcass that has the botulism toxin in it and is decomposing along the shore can often be a source for maggots, and other scavenging birds such as gulls can possibly get botulism. This maggot-cycle is particularly important for type C botulism.
What is Type C Botulism vs. Type E Botulism?
Type C avian botulism is the neuromuscular disease which typically affects dabbler ducks, and possibly other shorebirds, that forage in the mud in both inland and Great Lake coastlines (see the poster from Michigan Sea Grant – Dabblers & Divers: Great Lakes Waterfowl) and eat invertebrates directly. Type C impacts are felt in both inland lake and pond environments as well as in the Great Lakes shorelines.
Type E avian botulism usually impacts diver ducks in the Great Lakes where they dive deep and eat fish/mussels. Avian botulism outbreaks (type E) have occurred, with increased frequency in Lake Michigan along the northwest Michigan region since 2006, typically during the September-October-November time frame.
The mallard dabbler duck is the most abundant local duck in the Grand Traverse Bay region with strong population numbers and is the single species that was affected in the recent outbreak confirmed by the DNR. It is doubtful that a significant type C botulism outbreak would seriously impact population numbers of this species.
However, diving duck species such as common loons are a noteworthy species that have been impacted by type E botulism over a recent number of years. Common loons are a species of special concern in Michigan, and the full impact of the botulism kills are not known and a possible concern for loon population impacts in North America.
Additional Resources and Q & A
- Is it safe to walk dogs on the beach after a bird kill?
If you bring pets to the shore, keep them away from dead animals on the beach. Dead wildlife may contain potentially harmful bacteria or toxins. In cases where you think your pet may have ingested a contaminated carcass, monitor them for signs of sickness and contact a veterinarian if you suspect they are falling ill.
- Do I have to wash my hands after I touch a dead bird?
Yes, you should always wash your hands after handling any wildlife. Ideally, you should also wear gloves to handle any dead animal.
- Can I swim in the water?
You are not at risk for botulism poisoning by swimming in Great Lakes waters. Botulism is only contracted by ingesting fish or birds contaminated with the toxin. If you have concerns about water quality, contact your local health department or swim in a regulated beach area.
- How can people who want to help clean up the beach after a bird kill best protect themselves?
People who handle dead wildlife should wear protective gear, such as disposable rubber gloves or an inverted plastic bag over their hands. In cases where a diseased or dead bird is handled without gloves, hands should be thoroughly washed with hot, soapy water or an anti-bacterial cleaner.
- What is the best way to dispose of dead fish/birds in my area, especially after a botulism outbreak?
Be sure to follow local wildlife agency (e.g., Natural Resources, Fish and Wildlife, etc.) recommendations in handling dead fish and wildlife. Wear disposable, rubber or plastic gloves or invert a plastic bag over your hands when handling sick, dead, or dying fish, birds or other animals. In certain areas, burying of the carcasses is allowed, while in other areas incineration may be recommended. If birds are to be collected, they should be placed in heavy plastic bags to avoid the spread of botulism-containing maggots. The major goal should be to protect yourself, while also ensuring that the dead birds or fish are not available for consumption by other wildlife.
What to do if You Find Dead or Dying Birds
Any dead or dying birds that are found along the south shore of Grand Traverse Bay should be reported to the local Traverse City DNR office at (231) 922-5280, ext. 6832.
MSG’s Mark Breederland has been involved in providing educational programs on avian botulism for several years. If you would like a presentation for your work, social and school group, contact Mark at (231) 922.4628 or email@example.com.

Tests at a water treatment plant found elevated levels of the toxin microcystin, which is produced by blue-green algae, in the drinking water for Toledo, Ohio as well as communities in southeast Michigan. The toxin was part of the Harmful Algal Bloom, or HAB, that was found in the western basin of Lake Erie.
The City of Toledo leadership cautioned residents and the several hundred thousand people served by its water utility not to drink tap water, even if they boil it.
Exposure to high levels of microcystin can cause abdominal pain, vomiting, diarrhea, liver inflammation, pneumonia and other health problems, some of which can be life-threatening.
The all clear was given on Aug. 4 and residents were advised that the drinking water was once again safe for bathing, cooking and consumption.
However, HABs are a large and ongoing issue in the Great Lakes, particularly the bay regions (Green Bay, Saginaw Bay, Maumee Bay, etc.), that we will likely hear more about as the season progresses.

The city of Detroit and the Detroit River have experienced a great deal of environmental change in the last 313 years. Then, like now, it’s impassioned citizens and groups that work to help make the city and the river great.
On July 24, 1701, Antoine Laumet de LaMothe Cadillac established the City of Detroit with permission from French King Louis XIV. When first established, the French trading outpost was called Fort-Pontchartrain du Détroit. Today, some of us who live in metro Detroit often refer to the city by its area code, 313. While much has changed in the last 313 years, some things are still very similar. Detroit is still a place with impassioned people who are working hard to make Detroit a great place to live, work and play.

The University of Michigan Biological Station (UMBS) offers adults the chance to be students again! Participants may sign up for one of three mini-courses: Art in Nature, Fungi or Great Lakes Oceanography. Each class runs from Wednesday through Sunday, Aug. 20-24.
- Great Lakes Oceanography is a rare opportunity to learn about water quality, invasive species and Great Lakes ecology from three entertaining and enthusiastic experts. Gary Fahnenstiel, Tom Nalepa and Dave Schwab will teach the class on board NOAA Research Vessel Laurentian. All three men are Scientists Emeriti from the National Oceanic and Atmospheric Administration who are currently staff at the University of Michigan Water Center. Their respective areas of study are aquatic biology, invasive species, and hydrodynamics. Class participants will visit several locations in Lake Huron and the Mackinaw Straits. Along the way, they will use equipment and presentations from Fahnenstiel, Nalepa and Schwab to study the health of our region’s most vital natural resource.
- Art in Nature is for visual artists at any skill level. Instructor Ann Singsaas will provide demonstrations and inspiration in plein-air sketching, simple watercolor painting techniques, and the elements of design. Students will learn to keep a field sketchbook, take visual notes and capture both the detail and the broader essence of the natural world on paper. Working on location and in the studio, students will learn to sketch or paint with minimal equipment, providing a new way to document travels. Singsaas has degrees in both biology and art and advanced study in painting. She shows her artwork in the Midwest is represented by several galleries in Wisconsin.
- Fungi provides an in-depth look at nature’s recyclers. Local teacher and guide Marilynn Smith will use lectures and field trips to teach the structure, reproduction and ecology of fungi. Participants will also learn about the many uses humans have for fungi, beyond food. Smith has used her graduate training in mycology in the education and medical fields.
Course participants may commute or live at the Station, located on Douglas Lake, and eat in the dining hall.
“Our mini-courses provide people from across age groups wonderful opportunities to experience ‘North Woods’ environments and biota from new and interesting perspectives,” says UMBS Director Knute Nadelhoffer.

NOAA and its research partners predict that western Lake Erie will have a significant bloom of cyanobacteria, a toxic blue-green algae, during the 2014 bloom season in late summer. However, the predicted bloom is expected to be smaller than last year’s intense bloom, and considerably less than the record-setting 2011 bloom. Bloom impacts will vary across the lake’s western basin and are classified by an estimate of both its concentration and how far it spreads.
Harmful algal blooms (HABs) were common in western Lake Erie between the 1960s and 1980s. After a lapse of nearly 20 years, blooms have been steadily increasing over the past decade. Since 2008, NOAA has issued weekly HAB bulletins for western Lake Erie through the National Centers for Coastal Ocean Science (NCCOS) to give warnings of bloom development. Also, this marks the third time NOAA has issued an annual outlook for western Lake Erie.
