As I have recently found an unlimited [and free!] supply of mixed [including
cedar] shavings I searched the archives for this reference and found a post
by Bill Morrison regarding this subject.

Bill wrote "Be careful of using cedar (Juniperus, Chamaecyperus, etc.) as a
smoker fuel or even as a bedding for animals. It stimulates a liver
detoxification system and may be hazardous. Natural is not always nice...."

Bill, can you expand on this statement?  Since the recent article in ABJ
evaluating cedar as one of the best fuels, probably many beekeepers may
switch over to using cedar shavings.  Are we at risk? Thanks from all of us.
