The wood versus plastic issue was mentioned in the May 1993 of The Berkeley Wellness Letter. They reference "a yet-unpublished study," by "two microbiologists at the University of Wisconsin at Madison." Not much to start a literature search on, but the best I could do. The issue was also (gleefully) discussed on rec.woodworking at the time, but no-one seems to have mentioned the original reference. Anyway, according to the BWL, "On some [wooden] boards nearly 100% of the bacteria were dead, or at least gone, within three minutes. ... When contaminated boards were stored overnight under conditions conducive to bacterial growth, the wooden ones were bacteria-free the next morning, while the population soared on the plastic ones." It goes on to mention that the researchers found it hard to wash bacteria off plastic (especially if scratched). Old woods performed even better than new woods. The researchers did not (apparently) establish a mechanism for what was causing the bacteria to disappear on the wood. I guess the conclusion is that all these years when people were claiming plastic was a wonderful sterile material, that was a theoretical expectation and not an experimental finding - but people were not careful enough to distinguish. (Assuming these guys didn't just mess up their experiment of course). Stuart N-Street Cohousing
