Despite unusual bipartisan support on Capitol Hill and a strong push from the Obama administration, the bill could still die because there might not be enough time for the usual haggling between the Senate and House of Representatives, which passed its own version last year. Top House Democrats said that they would consider simply passing the Senate version to speed approval.
Both versions of the bill would grant the F.D.A. new powers to recall tainted foods, increase inspections, demand accountability from food companies and oversee farming. But neither version would consolidate overlapping functions at the Department of Agriculture and nearly a dozen other federal agencies that oversee various aspects of food safety, making coordination among the agencies a continuing challenge.
