San Francisco's Board of Supervisors has voted unanimously to ban performances of wild or exotic animals for public entertainment, including appearances in circuses or on the sets of movies, television shows and commercials.

The measure, approved 11-0 by the board on Tuesday and expected to be enacted in a final vote next week, would make San Francisco the largest city to adopt such a sweeping prohibition on the commercial use of wild animals for public amusement, supporters said.

The ordinance would not apply to domesticated animals, including dogs, cats, horses and other livestock or pets. Educational activities or exhibitions accredited by certain zoological and museum organizations would also be exempt.
