@ niando,
there is absolutely no danger of eating well prepared matumbo...in fact for the sake of satisfaction and the feeling that you have eaten some flesh, matumbo is the thing...
the only problem is that the matumbo has no nutrional value to the body...that is as per the medics...
the same applies to the intestines, but the intestines are a bit unique...once the intestines have been emptied manually the little stuff that remains in the intestines has a medicinal value...the mistake that butchers make is puting a hose on one end and opening the tap for a blast...and the real important pulp in the intestines lining is washed away.....
...besides, the presence of a safe alone does not signify that there is money inside...
