Modification of the Temporary Preventative Quarantine Area in Cameron County

Austin, TX – The Texas Animal Health Commission (TAHC) will modify the 223,000 acre Temporary Preventative Quarantine Area (TPQA) in Cameron County, Texas on November 17, 2016.

The TPQA was established two years ago when cattle fever ticks were discovered on cattle, horses, white-tailed deer, and nilgai antelope. Through enhanced surveillance in the area, the TAHC has now determined 14,460 acres located in the southwest corner of the TPQA meet requirements for quarantine release. The modified TPQA will consist of approximately 200,000 acres.

Although the TPQA is being reduced, the TAHC and USDA continue to closely monitor and respond to the expansion and northward movement of fever ticks.

Currently there are 17 individual cattle fever tick infested premises in Cameron County, 19 infested Willacy County premises, 2 infested Kleberg County premises, and 45 infested premises in the permanent quarantine zone along the Texas-Mexico border.

Within the TPQA, permanent quarantined zone, and on quarantined premises, all cattle, equine, and live or hunted wildlife (such as nilgai antelope and white-tailed deer) that are capable of hosting fever ticks, are subject to movement restrictions, inspections and treatment as prescribed by TAHC fever tick regulations. To read the regulations visit Title 4, Chapter 41 of the Texas Administrative Code. To learn more about hunting in a temporary or permanent fever tick quarantine zone visit the TAHC YouTube channel.
