Another
21 bison were shipped to slaughter from Yellowstone National
Park Thursday after testing positive for exposure to brucellosis.
That means a total of 145 animals have been hauled to
a meat plant over the past two weeks.
Another 154 have tested negative for the disease and are
being held in a capture facility inside the park, northwest
of Gardiner.
The National Park Service plans to keep those animals
in a corral until enough green grass emerges in the spring
to hold them inside the park.
One bull bison that tested negative for exposure was released
nearby. Mature bulls aren't being kept in the pen because
of fears they will damage the facility.
Calves and non-pregnant yearlings are being vaccinated
this year for the first time. A total of 79 animals have
now been vaccinated.
The goal of the controversial program is to reduce the
risk of bison spreading brucellosis to cattle, even though
such an incident has never been recorded in the wild.
Brucellosis causes most grazing animals to abort a fetus
during the first pregnancy after infection. It is transmitted
mostly through contact with infected birthing materials.
Montana's cattle herds are certified as brucellosis free.
The meat, hides and heads of the slaughtered animals will
be donated to Native American groups or individuals or
to food banks.
