Borden Dairy Co. filed for bankruptcy, becoming the second major U.S. milk seller to do so in two months as competitive pressures, declining consumption and falling profits made its debt load unsustainable.

Trucking and agriculture officials said the Chapter 11 bankruptcy filing by Dean Foods and its decision to sell its assets to the national milk marketing cooperative Dairy Farmers of America is not an indication of a broader problem in the sector, at least in the short term.

Top U.S. milk processor Dean Foods Co. filed for Chapter 11 bankruptcy and is in advanced talks with Dairy Farmers of America Inc. about a potential sale.
