USDA Confi rms New World Screwworm in Florida
T
HE UNI T ED States De-
partment of Agri- culture’s (USDA) Animal and Plant Health Inspection Service (APHIS) confi rmed the pres- ence of New World screwworm in Key deer from National Key Deer Refuge in Big Pine Key, Fla. USDA’s National Veterinary Ser-
vices Laboratories in Ames, Iowa, confi rms this is a local infestation of New World screwworm (Cochlio- myia hominivorax). This is the fi rst local infestation in the U.S. in more than 30 years. All of the potentially affected
animals are from the same Key. There have been no human or live- stock cases. Response efforts will include fl y
trapping to determine the extent of the infestation, release of sterile fl ies to prevent reproduction and disease surveillance to look for additional cases in animals. The initial goal will be to keep the infestation from spreading to new areas while eradi- cating the New World screwworm fl ies from the affected Keys. USDA used this technique to
eradicate screwworm from the U.S. and worked with other countries in Central America and the Caribbean to eradicate it there as well. Today, USDA and its partners maintain a permanent sterile fl y barrier at the Darien Gap between Panama and Colombia to prevent the establish- ment of any screwworm fl ies that enter from South America.
