CIDP

The condition afflicting five of the workers at Quality Pork Processors Inc. has been identified as a rare disease called chronic inflammatory demyelinating polyneuropathy or CIDP, which normally strikes fewer than two people per 100,000. In this instance, it may have struck 11 out of about 100 people in a particular part of the plant, state officials said. It is most often a chronic disease that results in nerve damage and can lead to disability.
