The health ministry said Thursday it will disclose the names of all 7,004 hospitals believed to have stocked blood products contaminated with the hepatitis C virus -- but not until year's end.

The Health, Labor and Welfare Ministry said it will order Mitsubishi Pharma Corp., the successor to Green Cross Corp., to submit a list of the names of 7,004 institutions to which it sold fibrinogen.

The ministry will make the data public by the end of December as it will take time to confirm the contents of the list, ministry officials said.
