- Japan allows importation of U.S. beef products, but restricts imports to products from cattle less than 30 months of age. This policy is inconsistent with international standards set by the OIE, which has recognized that both Japan and the United States present a negligible risk of BSE transmission. When will Japan adopt OIE-consistent BSE regulations and provide U.S. products with the same level of market access that the United States provides Japanese products?
