New World screw worm: USA stops imports of cattle and horses from Mexico.

Mexico is seen as not doing enough from the US perspective to combat the spread of the parasitic fly known as the "New World screw-worm." This fly is advancing further north towards the US border, which is now having consequences. US Secretary of Agriculture Brooke Rollins has suspended the import of live cattle, horses, and bison across the southern US border due to the flesh-eating New World screw-worm. She justified this decision by stating, "The last time this devastating pest hit America, our livestock industry took 30 years to recover. That cannot happen again." Her Mexican counterpart, Julio Berdegue, promptly criticized the measure but expressed hope for a swift agreement between both countries regarding the pest known as NWS, as reported by Reuters. "We do not agree with this measure," he said in a social media post, mentioning that it would be in effect for 15 days. According to the US Department of Agriculture, the suspension can take effect "monthly." Current efforts have been deemed inadequate. "There has been an unacceptable spread of the NWS to the north. Mexico must take additional measures to slow down the spread of this deadly parasitic fly to the north," the USDA stated. The fly infects both livestock and wildlife. The maggots burrow into the skin of living animals, causing severe and often fatal damage.
