The US and Mexico have launched a major effort against the New World screwworm, a flesh-eating parasite that threatens cattle herds. A new facility in Metapa, Mexico, will produce up to 100 million sterile flies per week, helping to control the spread of the disease. This plant is part of a global push to eliminate the parasite, with two plants now operating in the Americas and combined capacity exceeding 500 million flies per week.
