While we're on definitions, here's one on how the government describes what we eat.

The word "milk" means Grade A cows' milk, according to the Food and Drug Administration, which has control over such things. We know that because the Cove Mountain Goat Dairy of Wytheville, Va., asked the FDA to permit goats' milk to be used in federally approved ice cream and frozen custard, according to the Dec. 8 Federal Register (Page 60007). Specifically, the dairy wanted the definition of milk to be changed to "cows' milk or goats' milk."

The reason was business. The goat dairy operators claimed it was "discriminatory to restrict use of the name 'ice cream' to a product made from cows' milk only," says the notice, "particularly when the goats' milk products meet or surpass all the requirements for ice cream and frozen custard . . . . "

The FDA didn't buy the argument, though it acknowledged there is "a growing interest in providing for the use of goats' milk in the production of ice cream" and other frozen dessert products.

Instead of including goats' milk under the umbrella definition of "milk," the agency has "on its own initiative," the notice states, established "standards of identity for goats' milk ice cream, goats' milk frozen custard and goats' milk ice milk."

As a result, when you go to your neighborhood grocery for some ice cream, when you are getting goats' milk ice cream you should be told so on the label, thanks to the FDA.
