Canine Scent Detection Dogs Join the Fight Against American Foulbrood

A nine-year-old English springer spaniel named Maple is making waves at Michigan State University's Pollinator Performance Center. Maple, who was previously a human remains detection dog for the St. Joseph County sheriff's office, has been trained to detect American foulbrood (AFB), a bacterial infection that poses a significant threat to honeybees.

The idea of using canine scent detection in beekeeping quickly took shape between Meghan Milbrath, an assistant professor in MSU's entomology department, and Sue Stejskal, Maple's longtime owner, trainer, and handler. Milbrath was working to develop diagnostic and screening tools for honeybee diseases when she was introduced to Stejskal by a veterinarian who had attended a honeybee training session.

Stejskal, a Michigan State graduate with over 25 years of experience training dogs for law enforcement and other uses, set about retraining Maple to identify the scent markers of AFB inside beehives, adapting methods used in police detection work. Canine scent detection dogs have proven to be highly effective in detecting AFB, playing a valuable role in reducing disease risks for beekeepers.

One of the key advantages of using these dogs is their ultrasensitive sense of smell. Dogs can detect even the tiniest traces of foulbrood in a hive, surpassing many conventional detection methods that often rely on visual inspection or lab testing. Early detection of AFB is crucial, as it enables beekeepers to isolate and manage infected colonies promptly, significantly reducing the spread of this contagious disease within and between apiaries.

By identifying AFB early, detection dogs help minimize the need for wide-scale hive destruction or chemical treatments, which can be costly and hazardous for beekeepers. This reduction in economic losses and exposure risks is vital, especially considering that American foulbrood is one of several factors contributing to the decline of bees and other pollinators in recent years, alongside insecticides, climate change, and reduced food diversity.

The Pollinator Performance Center plans to document Maple's training process and publish a guidebook by Milbrath and Stejskal to help other teams adopt the technique. With about 465 bee species native to Michigan alone, every effort to reduce disease risks is vital for the protection of critical pollinators.

In summary, canine scent detection dogs are a promising and effective tool in managing American foulbrood. They offer a practical, non-invasive, and economical disease surveillance method that supports beekeeper health and hive sustainability. Programs training retired K-9s like Maple have been successfully integrated into agricultural and pollinator health initiatives, showing practical benefits on the ground. These efforts are being expanded by research teams and agricultural departments aiming to promote bee health and safeguard food production.
