A health ministry panel on Friday proposed banning all raw beef liver served at restaurants, after it was discovered that it contains the O-157 strain of E. coli bacteria.

The Health, Labor and Welfare Ministry will swiftly refer the matter to the Food Safety Commission under the Cabinet Office. Once the commission compiles a report, the new ban could be incorporated in the Food Sanitation Law and come into effect as early as June.

Violations regarding raw liver, considered a delicacy, would be punishable by up to two years in prison or a maximum fine of ¥2 million.
