Some bottles of Ark Land brand bottled water may contain arsenic,a pollutantknown to cause cancer in humans, Canada's food watchdog says.

The Canadian Food Inspection Agency issued a recall Wednesday of Ark Land brand Naturally Carbonated Mineral Water sold in 330-millilitre(UPC 7 85000 12033 9) and 500-ml (UPC 7 85000 12050 6) bottles with a best before date of 09/05/07.

Long-term exposure to high levels of arsenic may cause thickening and discolouration of skin, nausea, diarrhea, irregular heart rhythm and blood vessel damage. Short-term exposure can cause symptoms including abdominal pain, vomiting, diarrhea, cramping, numbness and loss of movement.

The water, imported from Armenia-based Arzni Source, was distributed in Ontario and Quebec and possibly across Canada.

The CFIA is monitoring the recall of the water from the marketplace.

There have been no reported illnesses associated with consumption of the product.
