A federal court has sliced off two pieces of a putative class action that disputes claims made on the labels of well-known breads by the country’s largest bakery and distributor.

The U.S. District Court for the Northern District of California on March 13 left intact the bulk of the plaintiffs’ claims that Bimbo Bakeries USA falsely labels many of the breads and related products that carry the Sara Lee, Arnold and Thomas’ brands as, variously, containing 100 percent whole wheat or serving as good sources of fiber and whole grains, when they don’t.
