US to combat screwworm with flies and dogs
US officials have identified the first case of flesh-eating screwworms in cattle in Texas since 1966, prompting a response that includes deploying hundreds of millions of sterile flies, establishing a containment zone, and using sniffer dogs at borders. The outbreak, in a three-week-old calf, has led to quarantine and surveillance measures, but concerns remain about the sufficiency of the current response. The screwworms pose a threat primarily to livestock, with some impact on human health, and authorities emphasize the importance of wound coverage and early detection to prevent further spread.
