Food safety authorities in Hong Kong found trace amounts of radioactive cesium 137 in powdered tea imported from Japan last week, according to The New York Times.
The sample tested at nearly one percent of the legal limit for radiation and was not considered a public health threat. Regardless, the importer voluntarily recalled the product.
According to the Times, in 2011 the Hong Kong government’s Center for Food Safety found three samples of vegetables imported from Japan with “unsatisfactory” levels of radioactive contaminants immediately following the partial meltdown of the Fukushima Daiichi Nuclear Power Plant.
In January, all rice grown near Fukushima passed radiation tests for the first time since the disaster, according to Reuters. Small amounts failed the tests in 2012 and 2013.
Japan suspended some agricultural and fishing exports after the Fukushima meltdown, but government officials have since lifted those restrictions.
