Gross but urgent: We eradicated the screwworm from the USA in the 1950s with nuclear reactors, and we can do it again. You're seeing in the news today that the screwworm is returning. It's a horrible fly whose flesh-eating larva cause mass livestock suffering and farmer financial loss.
The female screwworm fly mates only once. So we factory-farm raised 50 million screwworms per week in a soup of blood and meat, and sterilized them in bulk with 8000 roentgens of gamma rays from Cobalt-60 extracted from nuclear reactors.
We loaded them into cardboard boxes and put them on airplanes with a special device that opened the boxes and released the flies over wide areas. The sterile flies mated with native females, and the eggs laid never hatched.
10 million sterilized flies were released per day for months. State and federal personnel on the ground tracked progress, and it worked! Another triumph in the peaceful application of radionuclides.
This 1960 film shows all these steps in grotesque detail. It was digitized by us in 2023, thanks to sponsorship from
@ANS_org and is more relevant than ever. At the end the film warns that as long as screwworms exist in central and South America, the threat of them returning to the USA is real. Today it's happening. Perhaps we should restart the sterilization process and eradicate screwworms across the entire hemisphere.
