I recommend the 2004 double CD Abattoir Blues/The Lyre of Orpheus, released by Nick Cave and the Bad Seeds.
Oh, sorry. This is not a music blog, is it? I got confused after that Arie Perry post.
Very funny, Scout.
Pigs tissues are routinely used in the medical arena. Even heparin production involves the use of pig intestines. Does the advent of this PIN condition in abattoir workers suggest that xenotransplantation may now be posing newly identified risks with porcine tissue use?
To Anonymous:
This possibility warrants monitoring, but I suspect that exposure to porcine CNS tissue constitutes the risk, rather than intestines or other tissues.

Greetings,
I have been following the novel polyradiculoneuropathy that was identified at a pork abattoir with great interest.
MY concern are with not only the pig brains, but cattle brains and risk fact to Transmissible Spongiform Encephalopathy.
my concern ;
nasal aerosol CJD, never say never.
PLEASE note, certain orthopedic surgery and bone grinding is a risk factor for potential nasal aerosol transmission of TSE. There may be no documented case of this mode of transmission to date, however, this does not mean it has not, or cannot take place, and a keen watch should be mandated. There is recent science with other TSE that indeed this mode of transmission is real. AS well, precaution should be used when working with TSE and aerosol of the TSE agent at hand i.e. bone grinding for example.
PrPTSE has also been detected in olfactory epithelium in sporadic CJD patients at post mortem (11), and in the olfactory tract in vCJD

P10. Aerosol, Nasal, and Oral Transmission of Chronic Wasting Disease
Nathaniel D. Denkers1, Glenn C. Telling2 and Edward A. Hoover1
Conclusions: CWD can be transmitted by aerosol and nasal exposure--potentially implicating exposure via the respiratory mucosa in CWD. Micro-abrasions to the lingual surface substantially facilitated CWD transmission, suggesting a co-factor that may be significant in foraging cervids or other species. These findings could have implications for the mucosal transmission of other prion diseases.

Aerosol and Nasal Transmission of Chronic Wasting Disease in Cervidized Mice

These results demonstrate that CWD can be transmitted by aerosol (as well as nasal) exposure and suggest that exposure via the respiratory system merits consideration for prion disease transmission and biosafety.
