Final tests have confirmed that the strain of avian flu detected in pheasants in Clonakilty in Cork last week was not the virulent H5N1 strain of the virus.
The Department of Agriculture, Food and Marine said that there is no risk to public health as a result.
Laboratory tests from a broiler flock in the same area tested negative for avian flu, indicating that the virus has not spread.
Further test results relating to pheasants found in the Barryroe area of west Cork will be available in the coming days.
The birds there originated from the same flock as those in Clonakilty.
All the birds have been slaughtered.
The 1km temporary restriction zone will remain around the gun club in Barryroe while the further test results are awaited.
The temporary zone in Clonakilty has now been replaced by a low pathogenic restriction zone and this will remain for several weeks.
The department said full details about the origin of the birds have now been established.
The pheasants were imported from the UK three weeks ago.
However, indications are that the infection developed while they were in the Cork area, according to the department.
It reiterated that there is no concern about the consumption of poultry meat or poultry products.
