Animal carcases can pose a serious risk to both human and animal health, can jeopardise biosecurity and impose a range of environmental impacts if not properly disposed of. These risks can include polluting water courses, spreading disease and interfering with community amenity.The old practice of simply leaving a carcase anywhere in the paddock to rot simply does not stack up in a modern livestock industry where the implications of incorrect carcase management are better understood.
In fact, depending on where you live, there may be local, state or national regulatory requirements that relate to your on-farm waste management procedures and I encourage you to make yourself familiar with these obligations.
It is strongly recommended that carcass disposal is integrated into your on-farm biosecurity plan and that you consider the methods available to dispose of animal carcasses or animal waste products including hide, gut or bones after home slaughter or wool that is not suitable for baling. Another important consideration is the equipment you may need to assist in this disposal.
