CDC Investigating PIN Outbreak

While I doubt this is something that will affect you, unless of course you work at a pig meat processing plant, I thought you might want to know about it.

The US Centers for Disease Control and Prevention issued an update last week to its investigation of an outbreak of a paralysing condition that is affecting certain meat processing plant workers who use compressed air to remove the brains from the heads of pig carcases.

The illness is called Progressive Inflammatory Neuropathy (PIN) and its symptoms range from acute paralysis to gradual increase of weakness on both sides of the body, which in some cases happens over 8 days and in others over 213 days. The symptoms vary in severity from slight weakness and numbness to paralysis that affects mobility, mostly in the lower extremities.

The current thinking, which is yet to be proved, is that the meat workers are being exposed to splatter and aerosol droplets of pig brain tissue created by the compressed air blast, which liquefies the tissue before expelling it from the pig skull. Once inhaled, small particles of pig brain tissue are then is attacked by the worker's immune system which uses antibodies that also attack the body's own almost identical human nerve tissue.

Following the PIN outbreak in a Minnesota meat processing plant, the CDC launched a nationwide survey of large slaughterhouses and found two more meat plants that had used the compressed air system recently. One of the plants was also reporting cases of a neurologic illness among its meat processing workers.
