Pfizer announced this morning that it may sell its animal-health business, which employs more than 250 people in the Triangle.

The world's largest drugmaker will consider a sale or spin-off of its animal-health and nutrition divisions to focus more resources on expanding its pharmaceutical business.

The New York corporation could pick different strategies for each division, and doesn't expect to make any more announcements until sometime in 2012. Any transaction could take up to two years to complete.

The animal-health poultry division employs about 250 people in Durham and 20 more in Laurinburg.
