Dear Ms Kennedy
While hunting waterfowl last autumn in an area near Outlook , SK, I
encountered hunters who said that they had shot some ducks which smelled
so badly of pig manure that they had to be discarded . I suspect that
these birds were landing and/or feeding on the open sewage pits or pig
manured fields utilized by the industrial pig farms nearby.
For future reference, I have contacted the Saskatchewan Wildlife
Authorities to determine if they have a correct (legal ) procedure to
dispose of such birds. However , the real problem may be more
extensive. I have seen flocks of ducks, geese and sandhill
cranes land and perhaps feed in fields in this area which have just been
" pig shitted " - the somewhat crude, but colourful local term
for spreading sewage pit contents from these industrial pig farms onto
fields as fertilizer . This practice most frequently occurs late September
to late October when ducks and geese are undertaking their main fall
migration. The water like appearance of the open sewage pits is also
attractive to waterfowl, particularly in these drought plagued times on
the Prairies. I would think that, with the proliferation of the
number and size of these industrial pig farms in Saskatchewan,
Manitoba and elsewhere, more and more migratory waterfowl are being
exposed to these conditions.
Given the possible residues in the excrement from these "industrial
" pigs (antibiotics, hormones, etc. and perhaps disease), there could
be some danger to waterfowl which are exposed to this waste. Open sewage
pits would also be an excellent breeding ground for flies and mosquitoes
which can transmit viruses to and among birds. The possible inadvertent
human consumption of meat from birds, where exposure to pig waste is not
readily apparent, might have undesirable consequences. Without
wishing to be unduly alarmist, it would appear that a hazard potentially
exists here for both waterfowl and humans. Accordingly, I would ask
if any research is being or has been done in this area, or is at least
being considered.
Should a hazard be confirmed, there is the option, albeit expensive, of
having operators extensively treat the waste generated by these industrial
pig farms. Perhaps, again if a hazard is determined, the problem could
also be circumvented in a large part by covering industrial pig farm
sewage pits and curtailing the spread of pig waste during the main
migration period.
In this respect, I have noted the Minister of Environment's powers
under Section 36.1 of the Migratory Bird Regulations and the stipulation
under Section 35.1 which states in part " ... no person shall deposit
..... wastes or other substances harmful to migratory birds in any waters
or any area frequented by migratory birds."
I would appreciate your comments on the foregoing .
Your Sincerely
