Screwworm infestation threatens tiny deer in Florida Keys

An agricultural emergency has been declared in the Florida Keys over a fly larvae infestation threatening endangered deer found only in the island chain. In a statement Monday, Agriculture Commissioner Adam Putnam said the discovery of New World screwworm in the National Key Deer Refuge “sends shivers down every rancher’s spine.” Screwworm feed on the animals’ flesh, and infestations can be fatal to livestock and pets.  Refuge manager Dan Clark says about 40 of the 3-feet-tall Key deer have had to be euthanized over the last month due to the screwworm infestation.
