Milk may reach up to $8 a gallon if Congress does not step in.

A farm bill is set to expire, and Congress has been tied up with budget and fiscal cliff discussions, not taking any action on the farm bill. Without the bill, Washington would be forced to buy milk at highly inflated prices.

"I refer to it as a slippery slide, not a fiscal cliff," said Gregory Bizzarri, of St. Clairsville. "I think it's time for some bi-partisan support, some time for some statesmanship and some leadership in DC to get this straightened up," he said.

If the bill expires, the government would revert back to an outdated 1949 farm law.

"Eight dollars a gallon, to me, is just ridiculous. I mean as a mom, honestly, it's too expensive for us. To think that my kids can't have cereal, because it's eight dollars a gallon ... It is going to make an impact in our house," said Shannon Dombroski of St. Clairsville.

Kroger did not wish to comment.

Riesbeck's president Richard Riesbeck said, "We are confident that Congress will act timely to reinstate legislation that results in keeping milk prices stable for consumers. Recently our dairy suppliers notified us of a price decrease to be effective during the month of January, and we feel that this announcement indicates that we have escaped sharp pricing increases for the near future."

Only time will tell if that decrease continues, or if a sharp increase is on its way. Some shoppers said they don't know how they'd get by paying more than double for such a staple.
