Smithfield Foods has fired two employees and their supervisor for violating the company's animal-welfare policies, according to the Richmond Times-Dispatch.

The action follows an internal investigation in response to allegations by the Humane Society of the United States last week that employees mistreated pigs at the company's Waverly farm.

The company has announced it will use animal-welfare expert Temple Grandin and Richard Wilkes, DVM, the state veterinarian, to conduct an independent investigation at the facility following the HSUS allegations.
