In June, Texas animal health officials confirmed the state’s first case of anthrax of 2019 in a captive antelope on a premises in Uvalde County, which lies in a triangular part of Texas where anthrax is historically found in the soil. Now, they’ve confirmed additional anthrax cases, including in goats on a new Uvalde County premises on June 24, a horse from Sutton County on July 3, and cattle on a separate Sutton County premises on July 4.

All the premises have been placed under quarantine and producers were advised on vaccinating exposed animals and the proper disposal of affected carcasses, as outlined by Texas Animal Health Commission (TAHC) rules. Typically, quarantines are lifted 10 days from vaccination or the last death loss.

“It is common to see an increase in anthrax cases after periods of wet, cool weather, followed by hot, dry conditions,” said Andy Schwartz, DVM, TAHC executive director. “During these conditions, animals ingest the anthrax bacteria when they consume contaminated grass and hay or inhale the spores. Outbreaks usually end when cooler weather arrives.”
