General Mills this week announced a strategic sourcing partnership with the largest organic cooperative in the United States. The partnership with Wisconsin-based Organic Valley will help about 20 dairy farms add around 3,000 acres to organic dairy production. The program will assist General Mills to double the organic acreage from which it sources ingredients by 2019. Since 2009, General Mills has increased the organic acreage it supports by 120 percent. Also, General Mills will launch the Organic and Regenerative Agriculture Transition Council. The council, according to the company, will bring together sustainable agricultural leaders, farmers and industry stakeholders with the mission of advancing organic agriculture practices. General Mills attributes the moves to USDA data that says demand for organic food is increasing in the Unites States, but supply has not been able to keep up.
