A federal judge has ordered a Magic Valley dairy to show it is complying with FDA regulations before it sells any cows to slaughter for food. The consent decree was issued by U.S. District Magistrate Judge Candy Dale on Wednesday after the Food and Drug Administration sued G&H Dairy, contending that the business was sending cows to slaughterhouses even though the animals had higher-than-allowed levels of drugs in their systems. G&H Dairy milks about 4,500 cows at three locations in Wendell, Buhl and Dayton and sells the animals for meat when they can no longer produce milk. Last month, the dairy's attorney Robert E. Williams said the business was preparing to enter a consent decree with the FDA but it didn't admit the truth of the allegations.
