SACRAMENTO  (AP) — Gov. Jerry Brown has vetoed a bill that would expand food safety laws to cover indoor and outdoor playgrounds at fast-food restaurants.

In a veto message, Brown said Saturday that current laws enforced by local health jurisdictions are sufficient.

Under the bill, sponsored by Democratic Assemblyman Michael Allen of Santa Rosa, restaurants would be required to post signs informing customers that food is not allowed on play structures and to provide adults who ask copies of their playground inspection and cleaning plans.

Allen said the bill, AB1513, was promoted by research showing that restaurant playgrounds can be breeding grounds for illness-causing bacteria and are not always well-maintained.

Brown said there's not enough evidence that the problem warrants new state law.
