New topical Exzolt Cattle‑CA1 offers prevention and treatment options for New World screwworm

The threat of New World screwworm continues to be a concern for U.S. cattle producers and the U.S. ag industry.  In December, Merck Animal Health received conditional approval for Exzolt Cattle-CA1, a fluralaner topical solution.  The pour-on solution is effective for both the prevention and treatment of infestations caused by New World screwworm larvae. 

John Hutcheson, director of beef cattle technical services for Merck says the solution is also conditionally approved for the treatment and control of cattle fever tick.

Exzolt Cattle-CA1 is conditionally approved for beef cattle 2 months of age and older and replacement dairy heifers less than 20 months of age.  It is NOT approved for use in bulls tended for breeding 1 year of age and older, dairy calves, and veal calves. Cattle must not be slaughtered for human consumption within 98 days of treatment.
