SHANGHAI (Reuters) - Hong Kong decided on Sunday to suspend trade in live poultry after a spot check at a local street market revealed the presence of H7N9 bird flu virus, China’s official Xinhua News Service reported on Monday.

The report, citing a statement from Hong Kong’s food and environmental hygiene department, said that so far the source of the virus, found in a faecal sample, has not been identified.

The report said that the Hong Kong health department had contacted three of the four people working at the market and none had bird flu symptoms.

Hong Kong will hold a special meeting on Monday to evaluate risks and determine how long the suspension will last.
