Pinnacle Foods Group has purchased frozen-foods maker Birds Eye Foods for $1.3 billion in a deal that closed last week. The sale gives Pinnacle the largest market share in frozen-vegetable sales at 26.5%.

Rochester, N.Y.-based Birds Eye employs 1,700 nationwide.

The Birds Eye brand accounts for 26.5 percent of the nation's frozen vegetable sales, making it the top brand by market share.

Through Pinnacle Foods, it owns companies that manufacture and distribute products ranging from Duncan Hines baking mixes and Vlasic pickles to Hungry-Man frozen dinners and Lender's bagels.
