Load Planning called approximately 1 hour before arrival EDDF to advise they weren't sure exactly what was on the aircraft; due to confusion on the ramp with another EDDF flight. I relayed this information to the crew. They replied no handling problems with the aircraft; slight fuel overburn; but that's not unusual.  However; this is an unsafe operation. Positive verification of loading is required prior to issuing final weights.
Air carrier Dispatcher reported being advised by Load Planning that they were unsure of what was loaded on two flights departing for Frankfurt.
