Under the Canada Consumer Product Safety Act, teether fillings must not contain any living microorganisms. Health Canada’s sampling and evaluation program has determined that the liquid filling is contaminated with the fungus Rhinocladiella similis. The fungus is usually harmless, but may cause an infection in children if the teether is punctured and the liquid filling is ingested. As of January 14th 2026, the company has received no reports of incidents or injuries in Canada.
