Congress is pivoting to a one-year extension of the existing farm bill instead of trying to push through a new five-year bill.

Senate Agriculture Committee Chairwoman Debbie Stabenow (D-Mich.), who previously had opposed a one-year extension, told reporters Friday that she was shifting gears and preparing a one-year bill.

“That’s the only way you can do it, extend all of them,” she said.

Stabenow’s shift comes amid growing worries about a “milk cliff.”

The price of milk is set to rise dramatically at the beginning of the year if the current farm bill expires. The end of the current law would force the government to revert to a 1949 law for setting milk prices, which some analysts say could lead to a doubling of the milk price.
