Washington - (AP) - The Bush administration is likely to move its research on one of the most contagious animal diseases from an isolated island laboratory to the U.S. mainland near herds of livestock, raising concerns about a catastrophic outbreak.
Skeptical Democrats in Congress are demanding to see internal documents they believe highlight the risks and consequences of the decision. An epidemic of the disease, foot and mouth, which only affects animals, could devastate the livestock industry.
A simulated outbreak of the disease - part of an earlier U.S. government exercise called "Crimson Sky" - ended with fictional riots in the streets after the simulation's National Guardsmen were ordered to kill tens of millions of farm animals, so many that troops ran out of bullets. In the exercise, the government said it would have been forced to dig a ditch in Kansas 25 miles long to bury carcasses. In the simulation, protests broke out in some cities amid food shortages.
Foot-and-mouth virus can be carried on a worker's breath or clothes, or vehicles leaving a lab, and is so contagious it has been confined to Plum Island, N.Y., for more than a half-century - far from commercial livestock. The existing lab is 100 miles northeast of New York City in the Long Island Sound, accessible only by ferry or helicopter. Researchers there who work with the live virus are not permitted to own animals at home that would be susceptible, and they must wait at least a week before attending outside events where such animals might perform, such as a circus.
Infected animals weaken and lose weight. Milk cows don't produce milk. They remain highly infectious, even if they survive the virus.
The lawmakers set a deadline of Friday for the administration to turn over reports they requested. Otherwise, they warned in a letter to Homeland Security Secretary Michael Chertoff, they will arrange a vote next week to issue a congressional subpoena.
