(TOKYO) -- Radiation has been detected in milk and spinach produced near the troubled Fukushima Daiichi power plant, a Japanese official confirmed Saturday.
Milk from the Fukushima prefecture and spinach from the Ibaraki prefecture were found to be contaminated. The radiation level in the products, however, was negligible and not immediately harmful to humans.
Chief Cabinet Secretary Yukio Edano said that products are safe to consume. He explained that if someone were to drink the milk everyday for a year the radiation level would still be a fraction of a CT scan.
Importers of Japanese products are now testing for traces of radiation. Japan's primary food export partners include China, Taiwan, South Korea and the United States.
Meanwhile, another earthquake -- magnitude 6.1 -- hit northeastern Japan in the vicinity of the stricken plant Saturday. There have been no immediate reports of injuries, and it is unclear if the rumbling affected the effort to avert impending nuclear disaster.
Residents living within 20 miles of the Fukushima plant are being advised to wear masks and long sleeves outdoors.
Fears of radiation also prompted officials to test tap water in Tokyo and several surrounding prefectures. The results showed trace radiation within government regulatory limits.
