The drive-through chain also added a new independent director to its board.

OKLAHOMA CITY – During its recent shareholders meeting, Sonic Corp. announced a new antibiotic use policy for chicken as a part of its animal welfare program. In addition, the company announced the election of a new independent director to its board of directors.

As a part of its new policy, Sonic’s suppliers will not be allowed to use antibiotics medically important to human health on their animals for the purpose of growth promotion. In addition, all antibiotics must be administered by a licensed veterinarian and only for the prevention, control or treatment of disease. This policy is for chicken. The company does not currently have an antibiotics use policy for beef and pork, but it is starting the process of reviewing its policies.

Steven A. Davis joins the Sonic board effective immediately. He was former chairman and CEO of Bob Evans Farms Inc. and also served in executive and management positions at Yum! Brands and Kraft General Foods during his 30-year career in restaurant and retail.

"We are excited to welcome Steve as a new independent director to our board," said Cliff Hudson, Sonic Corp. CEO. “Steve’s executive experience in the restaurant industry combined with his brand management and consumer packaged goods knowledge nicely complements the breadth of experience on our board.”

Existing directors re-elected to the Sonic Corp. board are Tony D. Bartel, Lauren R. Hobart, Jeffrey H. Schutz and Kathryn L. Taylor. Continuing board members not standing for re-election include R. Neal Black, Kate S. Lavelle, J. Larry Nichols, Federico F. Peña, Frank E. Richardson, Susan E. Thronson and Cliff Hudson.
