An appliance or utensil manufactured under Jewish ownership does not require Tevila (immersion) in a mikva (ritual body of water).
Limited lots of Betty Crocker Pizza Maker Plus Model # BC2958CRW/CRK/CWK/CSK are manufactured under contract where the Jewish importer takes full ownership of all raw materials and components that will be used in the manufacturing of the appliance. These lots will have the OK symbol on the box. Additionally, Betty Crocker Pizza Maker Plus Model # BC2958CRW/CRK/CWK/CSK is contracted in a way that the importer retains ownership throughout the manufacturing process until the final product is produced.
There are varying opinions within Jewish law whether a utensil manufactured under Jewish ownership and is transferred to a non-Jewish retailer (for the sole purpose of re-selling it), requires Tevila (immersion). The Rabbinic authorities at OK Kosher have determined that it does not. When the Betty Crocker Pizza Maker Plus bearing the OK symbol is purchased at Bingo, it is acceptable without Tevila according to all opinions.
Products without the OK symbol on the box (or the symbol is erased or covered), are not included.
