Samples taken from a calf on a farm at Inchigeela in Cork have been sent to the Pirbright laboratory in England to be tested for foot and mouth disease.
The Department of Agriculture said the move is precautionary and it is "not concerned" with the latest development.
The calf was found to have lesions in its mouth and feet which is not necessarily an indication that the animal has contracted foot and mouth disease.
Results from the tests will be released next week.
