A Texas A&M extension article reviews the history of the Texas cattle fever tick eradication program and the quarantine zone along the Texas-Mexico border. It explains that the ticks transmit Babesia parasites that are fatal to most susceptible cattle, and that the parasites remain active in Mexico.
Continued tick presence near the border raises the risk of quarantine restrictions on cattle movements from Mexico, which can tighten feeder cattle supply in the US Southwest.
