New World Screwworm

The United States Department of Agriculture announced yesterday that a case of New World Screwworm has been detected outside of a Control Zone that was established in the Florida Keys last year in response to the outbreak in the Key deer population.  The new case was found in Homestead, FL in a domestic dog. Screwworm is a concern as these fly maggots, unlike most maggots, will continue to feed on perfectly healthy tissue, severely debilitating the animal and usually leads to death if not treated.  Extensive efforts have been mounted by USDA to protect the endangered Key deer and other animals.

The epidemiological report can be viewed here: https://www.aphis.usda.gov/stakeholders/downloads/2017/nws-epi-report.pdf.

This fly will lay its eggs on multiple species (including rarely, man) so per the USDA press release sent out January 9th:

 

“Residents who have warm-blooded animals (pets, livestock, etc.) should watch their animals carefully. Florida residents should report any potential cases to 1-800-HELP-FLA (1-800-435-7352) or non-Florida residents should call (850) 410-3800.  Visitors to the area should ensure any pets that are with them are also checked, in order to prevent the spread of this infestation.”
