Cases of young children swallowing button batteries resulting in serious internal injury and death continue to be reported in Canada. In 2020, the Canadian Hospitals Injury Reporting and Prevention Program (CHIRPP), an injury and poisoning emergency room surveillance system administered by the Public Health Agency of Canada, received reports of 125 button-battery related injuries in 2020. Between 2016 and 2019, an average of 114 cases per year were reported to CHIRPP. Health Canada is reminding parents and caregivers about the dangers of button batteries. If swallowed, button batteries can become lodged in a child's throat. The child's saliva instantly triggers an electrical current causing a chemical reaction that can burn through the esophagus, the wind pipe and the main artery. This can take as little as two hours. Even after the battery is removed, the severity of the burn can continue to worsen. Depleted or dead batteries can still carry enough charge to cause serious injuries and death. Button batteries are found in a wide range of household products accessible to children, such as toys, watches, calculators, remote controls, hearing aids, flashing jewelry, flameless candles, laser pointers, singing books and greeting cards. Children may also access button batteries from the battery's packaging or loose, improperly stored or discarded batteries. In reported cases of swallowing, young children found the batteries loose on the floor, in garbage bins, on countertops, or took them directly from the battery's packaging or from products. Even adults, particularly seniors, have confused button batteries with pills or food and have been injured.
