Genetically modified food is in the news again. I am really not sure how I feel about messing with things at the DNA level. Plant products such as corn and soybeans that have been genetically modified have been approved as safe by the FDA and are growing in popularity. An "animal" being altered causes a little more alarm in people than a modified plant. Initially I have apprehension because of not knowing the potential long term impact of consuming a modified species as food and how it could possibly affect the environment negatively. Elementary findings are saying yes to the safety of a genetically modified salmon. My question...Is it really safe?
Scientists can conduct short term studies at this early stage and do not know what long term results may occur from ingesting the revamped fish. The AquAdvantage Atlantic Salmon contains a growth hormone gene from another species of salmon to reduce the development time. Growth hormones have been linked to some cancers and the FDA believes that there is not potential risk from the new fish.
A large possible problem that is up for debate is "what if the genetically modified farmed salmon escape and intermingle with the wild salmon". Hopefully introduced disease, parasites and altered DNA of the new species does not have any affect on breeding, development, or habitat of the wild salmon if contact occurs.
Aqua Bounty Technologies is developing the hybrid salmon. The fish do not grow larger than the typical salmon. However, the growth time for a harvested fish is cut dramatically by half. The huge demand for increasing the quantity and reducing the time to raise salmon is causing the push for remodelling the DNA. Guidance, regulation and responsibility in manipulating DNA for
Genetically Engineered Animals was out lined in January 2009 by the FDA.
Playing this level of god, I believe, should be done with great care and caution. People are not known for always making safe decisions when science has been used to make advancements for man. Some of our greatest and most destructive moments in history have been from naive use of new technology.
