It is understood that more than 100 dead animals are currently waiting to be collected from farms around Donegal.
The situation has arisen as a result of a dispute between local knackery operators and the Department of Agriculture, Food and the Marine.
The issue is to be raised today in the Dail by Deputy Pat the Cope Gallagher.
He said he plans to ask the Minister to outline what interim measures he has taken to mitigate the problem of unburied animal carcasses that have been left on farms as a result of the ongoing knackery operators dispute in Donegal at present.
He will also ask if he has further considered relaxing the restrictions on farmers to carry out burials of such carcasses on a controlled basis on their own farms until normal services resume by the operators; and if he will make a statement on the matter.
It is understood dead animals are currently being held in storage in sheds in recent days.
However, there are fears this could lead to the spread of disease on farms.
