Cheyenne, WY – Testing has confirmed a second brucellosis-infected cattle herd in Teton County. It appears this infection spread from one cattle herd to another. This summer a single cow in Teton County was discovered with brucellosis. Now at least two and possibly four cows from a neighboring herd have tested positive. This is the fourth Wyoming cattle herd where brucellosis has been found in the last year. Oldham says testing shows the type of brucellosis in the second herd matches what was found in the case this summer. This new finding means it will be at least a year before Wyoming is able to regain its brucellosis-free status. The state has to go a full year without a case before it can get away from the costly testing requirements that it now faces.
