The Canadian Food Inspection Agency (CFIA) said on Tuesday that no trace of bird flu has been found in a gosling that died a poultry farm in Eastern Canada last week.

The CFIA lab in Winnipeg said Tuesday that further testing did not support last week's initial findings that the dead gosling at a farm in Prince Edward Island carried a strain of the H5 virus.

However, another test must be conducted to confirm the result, said Dr. Jim Clark, national manager of CFIA's avian influenza working group.

The reason for the different result could be due to insufficient or very low quantities of virus present in the sample, Clark said, adding the virus itself might have died or degraded while the sample was being transported to the lab for testing.

He said another test remained to be done that would definitively show whether there was any virus at any point.

The farm, located about 130 km west of Charlottetown,will remain under quarantine until the final test is complete.

Although different types of bird flu have been discovered in some birds in Canada, none have contained the deadly H5N1 strain.
