If your toilet was made by American Standard, Crane, Kohler, Eljer, Mansfield, St. Thomas or Gerber between 1997 and 2008, there's at least some chance it could randomly explode and cause "laceration injuries." So far at least 304 toilets have burst, resulting in 14 reported injuries.
The problem is about to get worse, though, or at least it could. The Los Angeles Times reports:
About 2.3 million units in the U.S. are affected by the recall. A parallel recall in Canada only involves about 9,000 toilets.
I have no idea how to determine when your toilet was made, so I guess the only real option here is to move to Canada, where health care is free and toilets are safer.
