U.S. companies in Mexico are increasingly worried about security and many are reconsidering future investments as drug war killings, kidnappings and extortion spiral out of control, said a poll.
 
The American Chamber of Commerce of Mexico, which represents the bulk of foreign direct investment in the country, said 58 percent of its members felt less safe in 2009 than they did a year earlier. Twenty-seven percent were reconsidering investments in Mexico due to security concerns, according to a poll of the American Chamber's members.
 
According to the poll, 39 percent of executives think improvements in security will take more than five years, up from 22 percent in the poll conducted a year earlier.
