13．The United States government has decided that food from cloned（克隆） cattle，pigs and goats is safe to eat．The Food and Drug Administration also says it found no risks in meat and milk from cloned animals．
The F．D．A．looked at studies for several years before it announced its decision in a final report this month．The United States Department of Agriculture supported the findings．But it says time is needed to clear the way for marketing meat and milk from clones．
The F．D．A．will not require any product to be registered（注册） as coming from clones．A producer would need to label a product"clone-free"．The agency says that could be misunderstood because the food is not different from other food．
But activists argue that the F．D．A．based its decision on incomplete research into possible risks．The Center for Food Safety criticized the use of studies supplied by cloning companies．Animal rights activists point out that cloning attempts often fail．They say cloning is cruel and can lead to suffering．
Congress （国会） has been trying to get the F．D．A．to do more studies．But the agency noted that experts in New Zealand and the European Union had come to the same findings about the safety of food from clones．Japan，South Korea and Taiwan say they want to study it further before taking action．
Products from cloning may not be widely used for several years．Clones cost much，which is why they are not widely used for feeding．The Agriculture Department says few clones will ever become food．Their traditionally raised animals would enter the food supply instead．
