4-24 and mold

There have been a few comments about Carolina Biological Supplies Formula
4-24 Instant Fly Food and mold.  I used this food for several years and
found that making it up with 0.5% propionic acid rather than water really
helped.  The flies didn't seem to mind.  When the food gets gray, it is
likely bacteria.  Once in a while that would happen, and we added a
cocktail of penicillin, streptomycin and tetracycline to the water used to
make the media.  Usually doing that for one round of turning would take
care of the problem.
