• Correction: San Francisco-Foam Ban story

    SAN FRANCISCO (AP) — In a story July 9 about a comprehensive ban on foam products in San Francisco, The Associated Press reported erroneously the nature and timing of bans in other cities. Los Angeles has a ban on foam food containers only in government buildings. And Portland, Oregon, approved a ban on such products in restaurants in1989, not following a similar prohibition in San Francisco in 2006.
