Immediately stop using these magnet sets, check that all pieces are accounted for, and safely dispose of the products. Do not purchase products with easily accessible small powerful magnets. Do not allow children to play with small items that contain powerful magnets. Teach children of all ages that magnets and items containing magnets should never be placed in their mouth, nose or ears. Even older children have unintentionally swallowed magnets. This can happen when they use them as fake tongue or cheek piercings, attach them to braces, or separate magnets with their teeth. Seek immediate medical attention for any child who has swallowed (or is suspected of having swallowed) one or more magnets. Read and follow the age recommendations, warnings, safety messages and assembly instructions for products before giving them to children. Regularly check the Healthy Canadians Recalls and Safety Alerts database for dangerous products and take action to remove items of concern.
