The WSOP has added this to the 2010 rules. I refer you to Chapter IV, Rule 37, Part B. The TD has the sole discretion as to the solution. Which in my interpretation can include disqualification.
From the 2010 WSOP Rules document, Section IV - PLAYER CONDUCT AND TOURAMENT INTEGRITY, Rule 37, Sub B:
"B. All participants are entitled to expect civility and courtesy from one another at every Tournament table and throughout the Tournament area. Any individual who encounters behavior that is not civil or courteous - or is abusive in any way - is encouraged to immediately contact a Tournament official. This shall include, but is not limited to, any player whose personal hygiene has become disruptive to the other players seated at their table. The determination as to whether an individual's personal hygiene is disruptive to other players shall be determined by the Tournament Staff which may, in its discretion, implement sanctions upon any such player who refuses to remedy the situation in a manner satisfactory to Rio.(emphasis added)"
Hope this helps!!
