Re: [DIYbio] Re: Stop Frankenfish?

More importantly it's irrelevant whether it survives acid. Toxicity is entirely specific to the larval insect midgut. It simply does nothing to nontarget species.

That's quite different to small-molecule toxins which are usually toxic to everything, but mostly to target species: at which point you're juggling doses and wondering about pharmacokinetics.

Respectfully disagree a bit. I think it's called pharmakinetics? It may survive acid in the stomach if protected somehow. If it's only on the surface, the major part may as well get washed off during processing. 
Still, ther's said to be no harm on it, ok. I'd rather prefere as little chemicals as well (although mycotoxins are a lot worse and mutagenic than most chemicals)

I can attest to this. I studied plant-sci in Cork, and the department
was mostly doing mutagenesis because it wasn't regulated in EU.

In perspective, though, mutagenesis is no worse than traditional
breeding, just faster. You have to be just as careful with
traditional/mutagenesis-accelerated. GE is better than both for speed,
reliability and predictability, but hey IT'S NOT NATUREL.

Also, animal feed isn't "GM Food" in the EU, so loads of animal feed in
the EU is GE too, and people quietly ignore that their cattle don't
develop massive, buoyant tumours and float away.
