An Ohio ice cream maker is voluntarily recalling some of its peanut-butter flavored products because of suspected salmonella contamination.

Velvet Ice Cream said Thursday that some of the peanut products bought from Sunland Inc. for use in the ice cream flavors could be contaminated.

The recalled Velvet products are mostly sold at convenience stores, ice cream parlors and small, independent retailers in Ohio, Indiana, Kentucky, Tennessee, Virginia and West Virginia.

The possibly affected Velvet brands include Peanut Butter Cup, Supreme Peanut Butter Cup and Buckeye Classic.

The U.S. Food and Drug Administration said it is investigating the presence of salmonella in samples taken from the Sunland Inc. production facility.
