Further tests in suspected BSE case
A second round of tests on the first suspected case of BSE from a farm in Ireland since 2013 are expected by the end of the week.
A five-year-old cow from a rare breed died in Co Louth but health chiefs have insisted it did not enter the food chain and was not sent to a slaughter house.
Amid concerns of the reputational damage to Ireland's beef and dairy industry from a return of BSE, investigations have continued for more than a week in a bid to determine the cause or source.
"A full investigation is continuing including a full epidemiological examination in an effort to establish the potential cause of this case," the Department of Agriculture said.
"Final results are expected towards the end of this week and Minister (Simon) Coveney will provide an update at that juncture."
No cases of BSE have been reported in Ireland since 2013 when only one was confirmed. There have not been more than 10 cases in one year since 2008.
In the last year, Ireland was the first EU country to re-gain access to the US beef market and to have the beef ban lifted in China.
