Taiwan finds radiation in fava beans imported from southern Japan, an official said. So Taiwan authorities are strictly checking imported foods for radiation.
The radiation was found on 14 kilograms (30.8 pounds) of fava beans from Kagoshima, said Tsai Shu-chen, an official with the Food and Drug Administration.
It is the first report of contaminated food being found outside Japan since the crisis at a nuclear power plant triggered by a devastating earthquake and tsunami nine days ago.
Kagoshima, at the southwestern tip of the Kyushu island, is more than 1,100 kilometres (700 miles) from the quake epicentre on the east coast of Honshu island.
"The beans may have been contaminated when they were airlifted to Tokyo's Narita Airport for a transit shipment to Taiwan," Tsai told AFP.
But she called on the public not to panic as the test figures showed that the beans contained just 11 Becquerels (Bq) of iodine and 1.0 Bq of caesium-137 per kilogram -- both well below the national safety levels.
The beans will be destroyed, she said.
