GE chicken sh*t

What next?!?
Now we hear claims that our farmland is being polluted by chicken manure containing genetically engineered material. Farmers are buying the chook manure from commercial poultry broiler sheds where imported ge-feed is being eaten by hens, then spreading it across their farms as fertilizer. Tests have shown that the ge material survives digestion from chickens and is still intact when it gets onto the pasture.
When will it end?
How much of our countryside has been contaminated with genetically engineered material now, given the recent news about ge-cottonseed feed that's being fed directly to dairy cows up and down the country?
This story featured over the whole of the front page of the latest Straight Furrow, (Read, valued, trusted, since 1941) 
Should be regard this story as alarming? Will farmers respond to the charge that they are carelessly contaminating the countryside?

I'll ask some questions of my farming councillor peers on Wednesday. They're bound to have a view.
