Hi Ted,
  Very interesting thread and it may take me some time to catch up.
  Question: Is there a safe fermentation method ? Which is  a good yeast  for us? baker's yeast  saccharomyces cerevisiae  may have some issues.   
Ann Rheum Dis. 2003 May; Anti-saccharomyces cerevisiae IgA antibodies are raised in ankylosing spondylitis and undifferentiated spondyloarthropathy.   
Rgds.,
