Has anyone looked at the possibility of cross
contamination of the canola? Although not a grain canola
is often grown in rotation with grains.
SEE    http://www.canola-council.org/manual/vlwhtbly.htm

Could volunteer wheat etc. be harvested with canola, get through the
sorting process and be involved in the pressing?
SEE    http://www.megamatrix.com/afpa/CanbraFoods/AgriProces.html

   It doesn't appear so but I willl make inquiries and
post this when I find out.
