Improperly stored corn is certainly known to support the growth of
A. flavus and thereby become contaminated with aflatoxins.  I
believe that many other types of stored grains and some other types
of nuts may also become similarly affected.  I have seen a hand-held
ultraviolet light used to qualitatively survey stored corn for the
presence of aflatoxin: the most potently carcinogenic of these
mycotoxins, aflatoxin B1, glows blue under UV illumination.  The
less toxic aflatoxins G glow green under UV.  I doubt that this
method is sufficiently sensitive to detect anything other than very
high levels of the toxins.
