[Taxacom] Correction [Cannibalistic offal (in nature); is such offal awful?]

[Steve Manning]

I seem to remember, vaguely, reading about a situation when some dogs 
ate some dead dog carcasses, but only as a last resort when it was 
clear what they were eating was dead and they were somehow otherwise 
deprived (don't remember any other details at all).

On a lighter note, I remember when I was a boy scout and we went on a 
camping trip where we camped overnight and cooked over campfires in a 
farmer's field.  There was some leftover cooked canned beef in the 
kettle and I remember remarking to one of my fellow campers that we 
had better eat all those leftovers to prevent the cows (nearby!) from 
making cannibals of themselves.

Of course we may all be cannibals to some extent (our intestines do 
slough off pretty extensively) if we don't mind "skipping a 
generation".  I can remember using a low spot at the edge of a 
village which was designated as the village toilet (no indoor 
plumbing). A pig followed me to the location and very quickly 
consumed the latest deposit.  Those pigs obviously knew a good food 
source when they saw it, and were being raised for human consumption 
(by grazing around the village)!

I've also read that it is routine in at least one Asian country for 
the toilet facilities to be at a pond's edge to facilitate disposal, 
and it is expected the local fish will use that for food and (some 
of) the fish are then consumed as an important part of the human diet.
