Fans at the U.S. Open report nausea and strong odors they describe as sewage and human waste entering Arthur Ashe Stadium during matches. Several outlets cite complaints from spectators who say the smell is noticeable while they watch tennis.

Both reports attribute the issue to odors originating from restrooms, with spectators characterizing the smell as “human waste” or “sewage” and describing it as strong enough to cause discomfort. The language used to frame the complaints differs by outlet, but the underlying accounts are similar: attendees perceive restroom-related odors spreading into the seating area and react by expressing distress, including claims that they are effectively “breathing in” the smell.

The outlets do not provide detailed information on the specific cause, timing, or whether tournament officials confirm the source. Coverage centers on firsthand fan reactions rather than independent measurements or an official explanation, leaving the precise circumstances unresolved in the articles provided.
