Insulin produced by genetically modified plants - with a human gene added - could be on the market in three years, a Canadian company has claimed.</b>
Sembiosys said it has made scientific breakthroughs and found a short cut through current drug regulations. The firm's CEO Andrew Baum said his company could become one of the first to sell a plant-based pharmaceutical.
However, critics believe that these products pose greater environmental and health risks than GM food crops. Most insulin is now produced by genetically modified bacteria, inside sealed tanks. The new technique uses GM plants grown out in the open.
If the firm can demonstrate that the plant-based insulin is identical with human insulin, it won't have to go through all the long and costly stages of full clinical trials.
However Clare Oxborrow, of Friends of the Earth, said the risks of contamination from pharmaceutical plants was actually greater than from food crops. She said there had already been contamination incidents with experimental pharmaceutical plants. One American company, Prodigene, was heavily fined for its mistakes in 2002. Similar problems have occurred recently with GM food crops.
<b>Pollution fears</B>
She said: "It's worrying enough when it's a crop intended for human consumption." "But when it might be a pharmaceutical crop in the future that contaminates the food chain, that raises serious worries and questions about the risks involved for human health."
Ms Oxborrow said the promised benefits would not be great enough to shift public opinion. She pointed to many other factors influencing public views - like the impact on the environment, potential health concerns and corporate control of the food chain.
However Mr Baum insisted: "The goodness of what we're doing is so clear - people who are dying of diabetes in the developing world will eventually get insulin - that I think people can understand it."I wonder how far-reaching this madness has to become before people do something about it.
Plants are being engineered to produce pharmaceuticals, and unleashed into the wild, where they can permanently pollute the environment without any way of removing them. The company is doing it so they can get a patent, and get rich, and bypass clinical trials for safety. And of course, there's the standard bull**** line about helping the developing world, even though the real plan is to get rich in the fat developed world where people actually, uh, suffer from diabetes because of their crappy diet.
This is almost as stupid as genetically engineered mosquitoes.
