Update on Cameron County Temporary Cattle Fever Tick Preventative Quarantine Area

March 6, 2015

AUSTIN – In October 2014, the Texas Animal Health Commission (TAHC) and the United States Department of Agriculture (USDA) confirmed the presence of cattle fever ticks on Cameron County premises located outside of the permanent quarantine zone. In order to protect the land, premises, and animals from exposure to cattle fever ticks, the TAHC created a temporary preventative quarantine area (TPQA) in Cameron County, which became effective October 7. 

Surveillance efforts have been ongoing since the TPQA went into effect. The TPQA originally started with six new premises located outside the permanent quarantine zone. Two months later, six additional premises were identified in the TPQA, which made a total of 12 infested premises. Currently, four additional premises have been identified. To date, there are 16 infested premises that have been identified in Cameron County. 

“Our primary goal is to protect the health of Texas livestock and to continue focusing our efforts on eradicating the fever tick out of South Texas,” said Dr. Max Dow, Incident Commander for the event. “We thank local producers and ranchers for their cooperation and we continue to ask for their help in complying with the TPQA requirements.” 

Frequently Asked Questions: 

Question: What are Fever Ticks? 

Answer: Fever ticks, known scientifically as Rhipicephalus (formerly Boophilus) annulatus and R. microplus, are capable of carrying the protozoa, or microscopic parasites, Babesia bovis or B. bigemina. Infected fever ticks inject the protozoan into the bloodstream of cattle as they feed. The Babesia organism attacks and destroys red blood cells, causing acute anemia, high fever, and enlargement of the spleen and liver, ultimately resulting in death for up to 90 percent of susceptible cattle.

Answer: Yes. As part of establishing the quarantine, livestock must be inspected and treated prior to movement.
