The BBC News reports that Bluegills are being used as the latest weapon in the war against terror. New York, Washington D.C., and San Francisco are now testing the municipal water supply on these critters. The fish are held captive in tanks into which a fresh supply of city drinking water is pumped several times a day. They are then monitored for signs of exposure to toxins, such as coughing.
NYC bluegills recently detected a diesel fuel spill two hours before any Department of Environmental Protection device, but word on the street is they’re not too strong in the bomb, hyjacked planes, and anthrax detection areas.
