A kitchen appliance with a safety interlock for processing foodstuff including a housing with a motor and a switch to actuate the motor within the housing. A bowl has a first actuator therein for selectively actuating the switch. A bowl lid is removably mountable over a mouth of the bowl and is mounted to a mouth of the bowl when the bowl and bowl lid are in a working position. A feed tube defines a feed cavity including a feed mouth. The feed tube has a second actuator in an operative relationship with the first actuator. A feed tube lid is pivotably and removably mounted to the feed tube and includes a tab. The tab contacts and moves the second actuator to its operative position to thereby actuate the switch through the first actuator when the feed tube lid is in a closed position.
