Final rule.


We are amending the Texas (Splenetic) Fever regulations by updating the scientific names for the ticks that transmit the disease, listing additional names for the disease, and removing all products except coumaphos from the list of dips permitted for use on cattle in interstate movement. These actions are necessary to update and clarify the regulations.


Effective Date: February 7, 2013

The regulations in 9 CFR part 72, “Texas (Splenetic) Fever in Cattle” (referred to below as the regulations), restrict the interstate movement of cattle from areas of the United States that are quarantined because of ticks that are vectors for bovine babesiosis. The disease is referred to in the regulations as splenetic or tick fever. Splenetic or tick fever is a contagious, infectious, and communicable disease of cattle that causes cattle to become weak and dehydrated and can cause death.

Section 72.1 lists the scientific names for ticks capable of transmitting microscopic parasites (Babesia) that cause bovine babesiosis. We are amending the list by clarifying that Margaropus annulatus is now considered a distinct species, and the genus Boophilus has been reclassified as a subgenus of the genus Rhipicephalus. In addition, we are removing R. evertsi evertsi from the list since this species is endemic to Africa and does not have established populations in North America.

Section 72.2 lists areas of the United States where splenetic or tick fever exists in cattle. We are amending this section to indicate that the terms southern fever, cattle fever, Texas fever, bovine piroplasmosis, redwater, and bovine babesiosis all refer to the same disease.

Section 72.13 concerns tickicidal dips for cattle and dipping procedures. Paragraph (b) lists the dips permitted for use on cattle in interstate movement. We are amending paragraph (b) by removing all dips except coumaphos, which is the only product being used currently. All other products have been removed from the market and their Environmental Protection Agency registration canceled by the manufacturers.

Currently, the title of part 72 is “Texas (Splenetic) Tick Fever in Cattle.” We are changing the title of the part to “Bovine Babesiosis” for the sake of clarity and technical accuracy.
