Washington, D.C. ? The nation’s biggest milk company, Dean Foods, said Thursday it will refuse milk from cloned cows.

The Food and Drug Administration has given preliminary approval to meat and milk from cloned animals and could grant final approval by the end of the year.

Dallas-based Dean Foods is a $10 billion company that owns Land O’Lakes and Horizon Organic, among dozens of other brands. In a statement issued Thursday, the company said its customers and consumers don’t want milk from cloned animals.

Milk companies worry that concern about cloning could turn people away from dairy products. So far, public opinion appears mixed. A September poll by the Pew Initiative on Food and Biotechnology found that 64 percent of respondents were uncomfortable with animal cloning.
