On cloned foods, a right to know

California is moving forward with a plan to require labeling on any meat or milk derived from cloned livestock. Scientists have found no cause for health concerns from eating cloned livestock products, and there are no products currently being marketed. But the Food and Drug Administration has given the preliminary stamp of approval to selling food from cloned livestock. Whether or not cloned animals are a good choice is up to the consumer, and there's an easy way consumers can decide what to buy: label it.
