pig-brains-illness

I’ve been following this story for the past few weeks.

11 workers in a Minnesota pork processing plant have come down with a strange neurological ailment which is said to be due to inhaling pig brains. One stated that she’s gotten progressively weaker over the 15 years she’s worked there…but never thought that it was due to the brains. The first thing I thought was, "Don’t they just throw the heads away?" And my second more grizzly thought was, "What are doing with the brains? What are they putting pig brains in?"
