Humboldt recently completed two other aquisitions, which combined with the WestFarm deal, will nearly double the cooperative's size.

In August it purchased a 40,000-square-foot distribution facility and nine acres in Stockton, Calif., from P&O Cold Logistics. In early November, Humboldt bought Arctic Ice Cream of Seattle.

Humboldt Creamery is a member co-op association owned by 62 Northern California dairy families and the oldest active dairy cooperative in the state. The company, which celebrated its 75th anniversary in October, produces a full line of dairy products including fluid milk, powdered milk, ice cream and frozen novelties in both conventional and organic form.
