Proper cooking will kill the larvae in the cysts and the meat will not be infectious. Filarias are long threadlike worms that can live in host tissue for years and make microfilarial larvae that circulate through blood and lymph system. When the eggs hatch and the resulting larvae mature in human skin, they make lesions and cause inflammation. This is not as serious as the microfiliarial larvae produced that migrate to the eye. In the eye inflammation causes blindness from retinal damage.
Prevention is fly control and drug therapy.
