12.The Beagle Brigade
Return to the United States from a trip abroad,and your luggage will get inspected by the U.S.Department of Agriculture's Beagle Brigade.Working with human canine officer partners,the beagles sniff out potential threats to American agriculture.
An orange or apple,for example,might harbor a Mediterranean fruit fly.Hams could carry a disease such as hog cholera.These and other pests could destroy farmer's crops and livestock."Once we introduce something that is not part of the environment,there may riot be any controls for it in the environment,"notes USDA's Lisa Davis at the National Dog Detector Training Center in Orlando,Florida."The best thing for us to do is to prevent it from coming across the border and becoming established.''
When a beagle sniffs specific food odors,it signals its partners by sitting.The human officer then investigates.When the dog is right-which happens 90percent of the time--it gets an edible treat.
"The dog is not out there working,"explains Davis."It's out there playing.It's a game to the dog."The handlers give the beagles plenty of food and loving.They make sure they get first-class medical attention,too.When the dogs finally retire after 9to 11years,the USDA finds caring homes for them.It's a dog's life indeed!
How well does the Beagle Brigade do its job?"On average,"notes Davis,"each year our 54teams prevent around 75,000 prohibited,restricted items."Since even one infested (为患的) item could cause widespread destruction,that's a great result for America's agricultural environment.
