The 47-page draft cautioned, however, that there was "only limited data available" on animal cloning. It urged consultation with scientists and consumer groups, which have in the past objected to allowing such products onto the market.
The EU's Food Safety Authority, which is based in Italy, was directed by the EU's executive office in Brussels last year to investigate what risks were involved in making projects for human consumption from cloned animals.
The 27-nation union currently has no laws regulating animal cloning and food. The European Commission is trying to decide whether legislation is needed, said Nina Papadoulaki, spokeswoman for EU Health Commissioner Markos Kyprianou.
"Based on current knowledge, there is no expectation that clones or their progeny would introduce any new food safety risks compared with conventionally bred animals," the preliminary report said.
Papadoulaki said the commission hoped the report would help EU officials determine whether there is public support for allowing cloned food onto supermarket shelves.
She said the commission would seek further advice from an ethics group specializing in science and new technologies, which includes 15 scientists, philosophers, theologians and lawyers.
