The FDA has spent 6 years debating whether meat and milk from cloned animals is safe to eat.
Many consumer groups and scientists say it's too soon to tell, that much more research is neded.
Right now, most cloned animals are being used for breeding, so it could be several years before their products appear on the market.
If the FDA gives the green light, it could prompt consumer wariness, plus a backlash from opponents in Congress, and overseas markets. The European Union has broad reservations about food from clones.
There are also ethical worries, because cloned animals tend to have more health problems at birth than conventionally-bred animals.
