A device and method for testing foodstuffs for the presence of microorganisms including an infeed unit for a package containing a foodstuff, a sample analysis device configured to take a sample of the foodstuff and test for the presence of microorganisms, a discharge unit for discharging the package, and a display for displaying the results of testing by the sample analysis device.

A control process for a conveyor system for conveying pallets or other objects comprises at least two mutually separate free-moving, i.e. not rail-mounted, conveyor units. Of the at least two conveyor units, a first conveyor unit is assigned a superordinate status and a second conveyor unit is assigned a subordinate status. The second conveyor unit therefore follows the first conveyor unit. To this end, the second conveyor unit detects a shift in the mutual relative position of the two conveyor units with the aid of a sensor and modifies its driving parameters depending on the shift in position detected by the sensor.
