Starbucks ( SBUX) has been forced to close 10 of its Mexico City locations in response to the swine flu outbreak.

One of the company's employees in the city is being treated for flu symptoms, but it has not been determined whether the employee has the same strain of the flu that has been said to kill 103 people in Mexico.

Starbucks says the Mexican government told the company to close the stores.

Shares of the company fell 2% on Monday trading to $13.25.
