The invention relates to a
processing line (10) which is designed and set up for
processing products from the
food processing industry, in particular stunned poultry (11), comprising: a transport device (12) which is designed and set up for the suspended transport of individual products along a transport path in the transport direction T; at least two
processing stations (13, 14, 15) which are arranged along the transport path, the at least two processing stations (13, 14, 15) being arranged one behind the other in the transport direction T; and a control device (16) for automatically controlling the processing line (10), the transport device (12) and each processing
station (13, 14, 15) being connected to the control device (16), which is characterised in that at least the first processing
station (13), which is upstream in the transport direction T, is assigned a detection means (17) which is designed and set up for detecting the processing result of the first processing
station (13) and forwarding the information to the control device (16), the processing line (10) additionally comprising means (18) for marking products, and the control device (16) being designed and set up for processing the information received from the detection means (17) and indicating the products which are defined as insufficiently processed by actuating the means (18) for marking along the transport path. The invention also relates to a corresponding method.
