The European Union (EU) currently has no plan to impose any trade restrictions on Mexico because of the swine flu outbreak, a spokesman said on Tuesday.

"We have no plans to impose any trade restrictions at present since there is no risk from food or animal products from what we know so far," the spokesman for EU Trade Commissioner Catherine Ashton told reporters at a daily news conference.

Until Tuesday, confirmed cases of swine flu infection have been reported in at least seven countries, namely New Zealand, Israel, the United States, Canada, Britain, Spain and Mexico.

Mexico is the center of the outbreak, where swine flu is believed to have killed more than 150 people. The EU has issued a warning against non-essential travel to the country.

The US government on Tuesday insisted its food supply is safe and pork meat does not transmit the swine influenza virus, urging all trading partners to refrain from trade restrictions.

With the deadly disease spreading globally, fears are on the rise that the outbreak could jeopardize the already fragile global economy and reverse its initial recovery.

EU Economic and Monetary Affairs Commissioner Joaquin Almunia said on Tuesday that the outbreak of swine flu is not helpful for the world economy but its economic impact should not be overstated.

"These things at such a delicate moment for the world economy are not helpful, but the economic consequences shouldn't be exaggerated," Almunia told reporters in Spain.
