"At eighteen months old you see the enormous difference here ... the salmon as it exists now is not profitable enough", says Andrew Kimbrell as he examines an enormous transgenic Salmon. It dwarfs its natural brother lying alongside it. His is one of the few voices questioning the fast-tracking of GM Salmon onto the marketplace.

While giant salmon are about to land in our pots and frying pans, independent scientists are only now starting to examine the science behind it. It's a game of catch up and the early indications are worrying. "Certainly if DNA was not cleared from the organisms, if that happens, then it may be the start of a highly unwanted process with regard to health". While researchers questions are ignored, humans are about to become guinea pigs for genetically engineered fish. There are worries that eating transgenic Salmon could weaken the immune system causing chronic illness, infertility, and even disrupt our own DNA. Yet these seem risks the pro-GM scientific community seems willing to take.

However, it is not just the impact these Salmon could have on humans which is worrying scientists. There are suggestions transgenic Salmon could lead to the extinction of Salmon in the wild. While Aqua Bounty, the company looking to market transgenic Salmon, claims the salmon will be sterile and unable to mate, scientists are contesting that their fertility will be impossible to regulate. If fertile transgenic Salmon escape to the wild the consequences will be dire. "One thing we have found is that the young don't survive as well ... it is quite likely the population could go extinct".

"What could be more important than deciding on the permanent genetic future of life on Earth, but we don't vote on that". While the questions over these Salmon remain, they will shortly be arriving on our plates and we won't be able to do anything about it. We won't even be able to tell when we're eating it.
