Ireland, Europe's second-largest beef exporter, found a suspected case of mad cow disease in a dairy cow in County Louth.

Tests are being taken to confirm whether the 5-year-old animal had mad cow disease, also known as bovine spongiform encephalopathy, or BSE, according to a statement from the country's Agriculture Department. Results should be available in a week. If confirmed, it would be the first case in Ireland since 2013.

The cow didn't enter the food supply and was discovered through a surveillance program testing animals that die on farms, according to the statement. Researchers will also examine other animals related to the infected cow.
