A popular catalytic cleaner is being shut down in Canada because of possible toxic chemicals in the substance.
The Canadian government says it is looking into the contamination of an ingredient in catalysts.
The Environmental Protection Agency (EPA) has banned the ingredient from use in all catalyts, and has sent a warning to all manufacturers.
The company responsible for the product, Energizer Canada, told CBC News it had found the source of the contamination, a source company.
The FDA is looking at the contamination and has ordered the company to stop production immediately.
The EPA has also told the company that if it does not take steps to limit exposure to the product to minimise risk, it will shut down its facility.
The product manufacturer, EcoPure Catalytics Inc., did not immediately respond to CBC News’ request for comment.
Energizer has been selling catalyzers since the 1970s.
