Reports of invasive and toxic hammerhead worms, also known as broadhead planarians, have surfaced in various locations across Ontario, including Newmarket, Hamilton, and the Kitchener area. This has raised concerns among experts about the potential dangers these worms pose to small animals and pets.
John Reynolds, a knowledgeable laboratory biologist, emphasized the surprising nature of these sightings, noting that these semi-tropical organisms are not commonly seen in Ontario. While originally from Southeast Asia, the worms likely entered the province inadvertently, possibly through nursery stock material from the U.S. or other sources.
The hammerhead worms have also been previously documented in areas such as the United States and Quebec, indicating their invasive nature and ability to spread rapidly. Reynolds explained that these worms do not travel far on their own but rely on transportation by humans. Additionally, cutting these worms can lead to the creation of new individuals, facilitating their spread.
Reynolds highlighted the critical issue of the neurotoxin produced by hammerhead worms, known as tetrodotoxin, which is a potent toxin also found in pufferfish. While this toxin can be lethal for small animals, its effects on humans are less severe, causing rashes and discomfort rather than fatality.
Experts, such as Emily Posteraro from the Invasive Species Centre, are urging the public to report any sightings of these invasive worms to the center or platforms like iNaturalist.ca. Specific location details and photographic evidence are critical for verifying these reports accurately.
The Ministry of Natural Resources and Forestry in Ontario is actively encouraging people to report hammerhead worm sightings through the Early Detection and Distribution Mapping System, an online tracking mechanism designed to monitor the spread of invasive species.
