In North Carolina, officials said that one of the young bulls brought in to be tested in his Northwestern Animal Disease Diagnostics Laboratory had more than 1,000 ticks. The owner lost four other cattle because of the same problem in 2018.

The tests confirmed that the ticks were long horned Asian ticks. The long-horned Asian tick is an exotic tick native to East Asia. Ticks have been reported for the first time in the United States in 2017. Since then, 67 counties in the United States have confirmed the presence of Asian longhorn tick populations. The cows died in Surry County, on the border with Virginia.

"This is the fourth confirmed case in North Carolina since 2018 and the first case reported this year. Previous cases have been discovered in Polk, Rutherford and Davidson counties, "said North Carolina State Veterinarian Doug Meckes in the letter.

Even more worrisome, the tick can breed without a male with a single fed tick capable of creating a localized population, said Meckes.
