Health Canada is advising Canadians that Panasilver, a product distributed by Activation Products Canada Inc., in Cobourg, Ontario, is not authorized for sale and may pose serious health risks.

Panasilver contains colloidal silver. Consuming products that contain colloidal silver may lead to the accumulation of silver in the body, which can cause a condition called generalized argyria. Generalized argyria is the permanent bluish-gray discolouration of the skin, eyes and nails. Children and pregnant women are particularly at risk. Colloidal silver can cross the placenta and could lead to problems with a developing fetus. Despite a lower dosage indicated for children, children are more susceptible than adults to serious health risks.

Panasilver is labelled for use as a “daily immune system support” for adults and children. This product was sold online and may have been sold at retail stores. At Health Canada’s request, Activation Products Canada Inc. has stopped sales and is recalling the product.

In addition to selling a product not authorized for sale in Canada, Activation Products Canada Inc. was also found to be operating without a Health Canada site or establishment licence, despite informing the Department that they had previously stopped all licensable activities. This is a serious safety concern. A site or establishment licence indicates that a company has processes and procedures in place that meet Health Canada’s requirements to track and recall health products. The licence also indicates that the company is manufacturing, packaging and labelling products in accordance with good manufacturing practices (a standard that helps to ensure the quality of health products sold to Canadians).

Health Canada inspectors seized equipment and products at the site. Health Canada is considering further actions to address this issue and will inform Canadians as needed should any new health risks be identified.
