Climate Change Drives Invasive Screwworm Surge Across Livestock Regions
GENEVA, SWITZERLAND - The World Organization for Animal Health has issued a global alert following a dramatic surge in screwworm infestations linked to shifting climate patterns. Reports indicate that the parasitic screwworm, a flesh-eating fly larvae that infiltrates open wounds in livestock and wildlife, has expanded its range into previously unaffected regions across Africa, the Middle East, and Southern Europe over the past 12 months. According to a joint assessment by the Food and Agriculture Organization and the International Atomic Energy Agency, rising temperatures and altered rainfall cycles have accelerated the screwworm's breeding cycle, with infestations confirmed in over 40 countries as of this week. Economists estimate losses exceeding $2 billion in the livestock sector, as farmers report reduced milk yields, increased mortality, and costly treatment protocols. The New Screwworm Eradication Programme, utilizing sterile insect technique, has been activated in 10 high-risk zones to curb the spread. Affected nations have implemented strict quarantine measures and mandatory reporting for veterinarians, while authorities urge breeders to intensify wound inspection and biosecurity protocols. Officials warn that if left unchecked, the screwworm epidemic could threaten global food security and trigger cross-border trade restrictions on animal products.
