The New World screwworm, a flesh-burrowing parasite, is approaching the US-Mexico border, threatening livestock and driving beef prices to record highs. - The parasite has been detected within 100 miles of the US border, prompting a ban on live cattle imports from Mexico.
- Ground beef prices have surged 77% since January 2020, reaching $6.90 per pound. - The USDA is building a $750 million facility to produce sterile flies, but officials warn an infestation is likely.
- Emergency medications like ivermectin are approved, but overuse could lead to resistance. Officials emphasize that eradication will be a long-term effort requiring cooperation across agencies and the livestock industry.
