Holy potatoes, is BNP72 back yet? Shocked

But anyway. I'm sure I recall an informative post by Stinkwheel regarding the BSE/CJD and being linked to the 'cake' not being cooked correctly, either time or temperatures, and something to do with regulations being changed for the worse.

Did I imagine, or did it actually happen? Confused

Yes there was something Stinkwheel posted about about feeding cow remains to cows without heating it to a suitable level to kill prions, but I'm still very much on the side of cannibalism being wrong.

In short, they were feeding rendered protein of animal origin to cows. Something I also disagree with. However they were doing it.

They moved from a batch rendering process to a continuious rendering process which didn't reach such a high temperature for such a long time. As it turns out, the infectious agent for BSE, (called a prion which is a self-replicating protien with a bit of nucleic acid attached that forms part of the nerve sheath) is very heat stable due to not having much of a 3D structure. The batch process destroyed it, the continuious process did not.

Prion material from a varient of a prion based disease in sheep called scrapie (which has been about for hundreds of years) made it into the cattle food chain and jumped the species barrier.

This new varient has shown the ability to jump into other species too. One of which was in humans where it caused a new varient of a brain disease called CJD (other varients tended to be spread by cannibalism or contaminated surgical instruments) and everybody lost their minds. Billions spent, trade embargos on British beef. Doomsayers predictingtens of thousands of deaths and the fall of civilisation as we know it. There have been fewer than 200 cases total in the UK to date.

Fewer than 200 cases identified so far and can only be identifed posthumously.

(Waves to Easy....)

I wondered if you would mention scrapie. Does it have anything to do with the fact we only eat lamb and not mutton or is the beef we eat and the sheep we breed from are actually the same sort of age?

I think a better way of presenting my question is...

How come scrapie is transmitted within sheep without the brain munching?

Not eating much mutton is a cultural thing. We used to export most of our mutton to France.

Most of the beef we eat is pretty young. They did identify age of animal as a risk factor and during the height of the BSE crisis, only cattle under 30 months old were allowed into the human food chain. They backed this off once all animals and the offspring of all animals which could have been exposed to the infected cattle feed were dead.

They still remove parts of the carcasses that were identified as specified risk material (such as cow brain or spinal cord in animals over 30 months) and do not put it in the food chain, it gets dyed blue and disposed of.

I don't think there were any cases of a scrapie varient crossing into humans. It seems like there was a pretty specialised one which jumped from sheep to cattle and was then amplified by feeding contaminated cattle protein back to cattle.

Yeah, forced cannibalism, not one of the greatest moments in animal husbandry. Human cannibals get a type of CJD called "kuru". So yeah, eating brains of your own species probably isn't a fantastic idea in general.

There can be vertical transmission (mother to offspring) and there is a genetic predisposition to forming abnormal prions in some animals. There are ongoing moves for genetic testing and breeding it out of the top level breeding stock.

Did I imagine it was a bureaucrat, possibly EU, idea to change how the 'cake' was produced (from batch to continuous) or am I just very anti EU? Laughing

There was a slacking off in regulations. Not sure which end it came from.

I suspect homegrown because it would have been back in the early 80's when the EU was still the EEC and hadn't really started meddling with things that were none of their fucking business.

In fairness, I don't think anyone could have predicted this result. Yes the forced cannibalism thing was wrong on all sorts of levels but I don't think anyone knew much about prion spread or their ability to withstand rendering. It was probably shear luck the batch rendering hit a high enough temperature to be effective.

If you want some anti EU rhetoric. I still maintain there must have been a huge cover up of BSE cases on mainland Europe. There was a massive calf export trade between the UK and France in the run up to BSE. I can't see how they weren't getting cases. Infected animals MUST have crossed the channel. I wouldn't be surprised if infected feed did too.

There was something similar in deer that claimed it was spread more easily in the ground from deer remains. Other people had said the threat was exaggerated because they were against farmed deer or self sufficient hunting communities.

Shifty I eat quite a lot of mutton, get it from the halal shops. Its cheaper than lamb and still has that nice sheepy taste, albeit somewhat stronger Shifty

Am going to get scrapie and go baaa-baaa crazy?

I visited a rendering plant.
The smell and death is memorable.

Carcass piled at one end, bagged cake, fats, oils and bone meal out the other.

Interesting process uses hot solvents to remove oils and fat from the tissue. The solvent is then recycled with oils, fats and tissue removed.

It's like Gawd working in reverse in a way. Laughing

And maggots... Sick

Sheep with scrapey get itchy so have you been manically rubbing your arse up and down a telegraph pole?

As Stinkwheel says there is a lot of politics and likely a lot of covering up.

Pretty sure its still in force but there was a ban on the export of UK blood products into the US due to fears over VCJD and yet we are still dealing with the fallout of contaminated blood products entering the UK from the US.

Its very easy to claim you have never had a confirmed case of VCJD if you never test for it or only test animals that you know are clear. It wasn't an EU cover up, it was a worldwide cover up blaming the UK for feeding practices that were followed worldwide.

Cheaper for a farmer to slaughter a herd and sell the meat at a loss than to report it, have their herd slaughtered and incinerated on suspicion with no financial backup and definitely cheaper for a Government to simply buy and slaughter on suspicion than face having all exports banned.

One upshot of this is the UK meat trade due to admitting problems is now a lot cleaner than other countries. Even wild animals like Deer in the US are now facing Prion disease (CWD) due to the refusal to admit there was a problem.

British can't donate blood in Canada. People who were in Britain during Mad Cow Event can't donate blood in Canada.

Kunts who work in Saudi (and other Muddle East Cuntries) can't donate blood in UK. (Coz Neglected Tropical Disease NYDs. WHO directive.) Some wee sandfly bugger is one vector.

That all ended with all other restrictions when they started letting the gays donate.

They apparently test all donations.
