- Exzolt Cattle-CA1 is a single-use pour-on applied in a narrow strip along the back, approved for beef cattle at least two months old and dairy animals under 20 months, and available by prescription in 250 ml, 1-liter, and 5-liter bottles.
- FDA leadership said New World screwworm has not been detected in the United States, whereas cattle fever tick is present, with recent screwworm detections reported in northern Mexico near the U.S. border.
- Texas Agriculture Commissioner Sid Miller praised the decision as a needed tool for protecting herds across production stages.
- Merck said the FDA also conditionally cleared Dectomax-CA1 (doramectin injection) for New World screwworm, adding another option for veterinarians.
