USDA’s Animal Plant and Health Inspection Service is inviting public comment on an evaluation of the fever tick status of the State of Chihuahua, MX. 

The evaluation was completed in response to a request from Mexico, and determined that the State of Chihuahua, except for the municipalities of Guadelupe y Calvo and Morelos, are free of fever ticks. The evaluation also determined that cattle imported from the area pose a very low risk of exposing animals within the United States to fever ticks.

Fever ticks attach to cattle and can cause a parasitic infection that often leads to fatal diseases such as bovine babesiosis.

We are making the evaluation available for public review and comment.  After the comment period closes, we will thoroughly review all comments received, and will notify the public of any changes to the regulations. 

This notice is on display in the Federal Register at: https://s3.amazonaws.com/public-inspection.federalregister.gov/2016-11150.pdf.  Members of the public will be able to view the evaluation and submit comments beginning tomorrow at: http://www.regulations.gov/#!docketDetail;D=APHIS-2015-0042.  Written comments can also be submitted through the mail: Docket No. APHIS-2015-0042, Regulatory Analysis and Development, PPD, APHIS, Station 3A-03.8, 4700 River Road Unit 118, Riverdale, MD 20737-1238.
