Reuters reports, South Korea, Hong Kong, Singapore and the Philippines will test Japanese food imports for radiation, officials said on Monday, and other countries may also step up monitoring as Japan tries to contain a nuclear crisis. Singapore''s agri-food and veterinary authority (AVA) said it would test imports from Japan and particularly fresh produce. South Korea''s Food and Drug Administration said it would test fresh agriculture and forest products for radiation, although it added it was not a big buyer of such products from Japan. Officials said testing of seafood was also being considered—South Korea imported 84,000 tons of fish from Japan in 2010. Thailand''s public health ministry said it had no plans at present for extra monitoring of imports from Japan, but Malaysia said it would step up checks on food shipments.
