The Seattle City Council recently advanced a resolution supporting a statewide and national ban on nontherapeutic uses of antibiotics in livestock production.

The aim is to help prevent the proliferation of antibiotic-resistant bacteria in the food supply, according to a statement from the Seattle mayor’s office.

City councils in four other U.S. cities — Pittsburgh, Pa.; Cleveland, Ohio; Providence, R.I.; and Redhook, N.J. — have passed resolutions supporting a ban on nontherapeutic uses of antibiotics in livestock production, according to the statement.

The Seattle measure cleared a committee and heads for a full council vote on April 7.

The resolution comes as the Ronald Reagan UCLA Medical Center and UCLA Medical Center in Santa Monica, Calif., begin offering antibiotic-free ground beef, ground beef patties and chicken breasts on their menus in a “symbolic” move to support efforts to control so-called superbugs, the Los Angeles Times reported.

The hospital is also looking at adding antibiotic-free stew beef, tri-tip and chicken quarters, the paper reports.
