Lauran Neergaard of the AP again breaks another disturbing story about the dangers of our food supply.  She reports this evening that Investigators are preparing to test pig brains as they struggle to tell what is causing a mysterious nerve illness affecting pork plant workers in Minnesota and Indiana.  The CDC and Minnesota Department of Health are calling the condition "progressive inflammatory neuropathy"  – meaning something is triggering inflammation serious enough to damage nerves.  All 14 employees who became ill worked near powerful compressed air systems that blow brains out of pig heads at what is known as the head table.  Both plants have stopped using the process.
