Genetically modified salmon will not go on sale in the U.S.

The House of Congress has voted to ban the Food and Drug Administration from passing the fish fit for human consumption.

The FDA had said last year that they thought the fish, which grows twice as fast as normal salmon, appeared to be safe.

And they were expected to rule on the modified food later this year.

But an advisory panel had indicated that more studies would be needed before it could be served on the nation's dinner tables.

If the FDA had approved the salmon it would be the first time the government allowed such modified animals to be marketed for human consumption.
