Rep. Roy Sends a Letter to Ambassador Johnson, U.S. Ambassador to Mexico, Urging Action Against the New World Screwworm (NWS)

May 29, 2025 Press Release Washington, D.C. – Congressman Chip Roy (TX-21) sent a letter to Ambassador Ronald D. Johnson, U.S. Ambassador to Mexico, urging for action against the northward spread of the New World Screwworm (NWS). "While the U.S. has effectively eradicated NWS in the past, the U.S. Department of Agriculture (USDA) reported that the NWS has recently been detected as far north as the Mexican state of Veracruz, roughly 700 miles from the U.S.’s southern border. If an outbreak were to occur in Texas, the USDA estimates it could cause $1.8 billion in damage to the state’s economy – devastating ranchers’ entire livelihoods. If left unaddressed, the NWS will have catastrophic impacts on the U.S. cattle industry and our country’s food supply. While Mexico has taken some action to try and contain the NWS spread, those efforts remain wholly insufficient. I respectfully request that you leverage all available diplomatic tools to urge the Mexican authorities to fully cooperate with U.S. officials and spur Mexican authorities to take aggressive action to contain the NWS spread. My constituents in the 21st congressional district, many of whom rely on ranching for their livelihoods, cannot afford delays." Read the full letter below.
