Agricultural committees in deal to avert milk price spike

Farm-state lawmakers have agreed to a one-year extension of the expiring U.S. farm law that, if enacted, would head off a possible doubling of retail milk prices to $7 or more a gallon in early 2013.

The extension would end a 32-month attempt to update farm subsidies dating from the Depression era, when farmers were crushed by low prices and huge crop surpluses, to meet today's high-wire challenges of tight food supplies, high operating costs and volatile markets.
