I'm not sure how it's affecting people's health, and given that the smell seemed to start just before the hospital it's a lot of people breathing in foul air.
Between January 9 and 16, 13 odour complaints were made to Horizons. Those smells were caused by a sump pump in the raw bin area not working, and by "expired" heads and hocks sent to the rendering plant.
Money must be spent to fix this problem and hopefully Affco have thrown everything at this malfunction to stop the smell once and for all. Or else don't accept rotting material, or treat it to disguise the smell.
