The illegal dumping prompted the involvement of Bio-Security Tasmania, which has inspected the site because of the health hazard it posed.

Animal carcasses can carry hydatids disease and, although the risks of this are low, this can be passed on to dogs and humans. 

The Centres for Disease Control and Prevention describe hydatids as a parasitic tapeworm which can cause ``harmful, slowly enlarging cysts in the liver, lungs and other organs that often grow unnoticed and (can be) neglected for years''.

The repulsive discovery was made by an adjoining landowner who contacted TasRail which, in turn, posted the news on Facebook.

``It’s just gross,'' a TasRail spokeswoman told The Examiner.

``The biggest issue is the potential health problem.''

TasRail would now have to pay for the removal of the rotting carcasses, including the application of recommended materials which is expected to cost thousands of dollars.

``TasRail will also need to construct barriers, at its cost, to the dirt track entry into the area to prevent future access to the area,'' the spokeswoman said.

Anyone with information as to the likely offenders is asked to contact TasRail on 6335 2603.

It is illegal in Tasmania to feed, or allow dogs access to cooked or uncooked offal from cattle, sheep, goats or pigs.

Offal refers to all internal organs from these types of animals.
