The Food and Drug Administration's five-year analysis concluded that animals produced from cloning practices are not a danger to the human food supply.
The FDA study stated that special labels are not necessary for food from cloned animals or their offspring. Consumer groups say labels are a necessity because people are uncomfortable with the concept of cloned livestock.
Animal cloning is expected to be used primarily for breeding exceptional animals – not for rapid animal production.
Final approval of cloned animals for food is still months away, pending public comments to the FDA.
