No radiation has been detected in West Coast fish stocks following the Fukushima nuclear incident, the Canadian Food Inspection Agency is reporting.
Twelve fish samples were tested on August 22 and 23 and all were below Health Canada action levels for radioactivity, the CFIA announced Friday.
The tests were conducted because of concerns raised by the failure of the Fukushima Daiichi nuclear plant in northeastern Japan in March.
The concentration of radioactive iodine-131 in seawater in the area soared to 1,250 times the normal figure, the Japanese Nuclear and Industrial Safety Agency said in March.
Radiation began seeping from the plant when a magnitude 9 earthquake and a tsunami on March 11 knocked out its cooling systems. The contamination has made its way into milk and vegetables, including broccoli, cauliflower and turnips tested in Japan.
But radioactive iodine-131 has a half-life of eight days, which means in several weeks its threat reduces to a minuscule level, according to nuclear experts.
Prior tests found no concerns
Previously the CFIA has said it tested 165 food and feed products imported from Japan after the disaster and found all were below Health Canada's levels for concern.
The agency also tested 34 samples of domestically produced milk from British Columbia and all were found safe for consumption.
Negligible levels of radioactivity in the atmosphere were also detected along the West Coast by monitoring stations following the disaster.
"The radiation levels found on the West Coast are less than the natural levels of radiation that would be detected when it rains or snows," said a statement previously released by the CFIA.
