An isolated case of H1N1 has broken out among a herd of pigs in Quebec.

The swine flu virus was identified on July 24 at a lab in Winnipeg after symptoms became apparent in the animals in late June.

The entire herd was isolated and there are no human infections of the virus associated with this outbreak, which is considered very light, said Alain Laperle, a pathologist from Quebec's agriculture bureau.

The board would not reveal which farm the tainted pigs came from, said Cl�ment Falardeau, an official with the agriculture bureau.

"There is no danger to the public's health and the since pigs have been cured, we can't give out information to that effect," said Falardeau.

Officials said this outbreak does not affect any Quebec pork products and that they are safe to eat.
