Brucellosis Found Again in GYA


The following is a press release from the Wyoming Livestock Board:

The Wyoming Livestock Board (WLSB) recently received information from Montana animal health officials reporting the finding of an adult, beef cow at a Montana auction market having serological evidence of brucellosis.  The cow most recently originated from a ranch in Park County, WY.  Wyoming animal health officials are currently conducting an epidemiological investigation of the case, and making plans for further testing of the suspect cow and the herd from which the cow originated.

This week Russell Nemetz spoke with Wyoming State Veterinarian Dr. Jim Logan about this latest case.


Dr. Logan also explained whether Wyoming would lose it’s brucellosis class-free status.


Pending further diagnostics this herd has not yet been designated by USDA APHIS as an infected herd.  Tissue samples will be collected from the serologically positive animal and will be submitted to the Wyoming State Veterinary Laboratory (WSVL) and the National Veterinary Services Laboratory (NVSL).  Culture results will not be expected until the end of February.

NOTE:  The USDA’s Animal and Plant Health Inspection Service (APHIS) will be taking comments through February 25, 2011 regarding their interim rule for dealing with brucellosis.  Read “APHIS Finally Changing Brucellosis Rules!” for more details.
