Food supply threatened by 'flying piranha' putting 'fist-sized holes' in animals: report

Once thought to be eradicated, the screwworm could be screwing up our food supply as soon as this summer, according to a Bloomberg report.

The screwworm affected live stock ranchers from the 1930s through he 1980s.

The insect is essentially a “flying piranha” that eats its host from the inside out and has the ability to kill a full-grown steer in 10 days.

Eggs are laid in a wound, eye, or even the nose, or the udders of any animal. The eggs then hatch into larvae, which burrow or “screw” deep into the host’s flesh.
