A producer uses offshore cages for a GLOBALG.A.P. certified salmon production process. In the vicinity of these cages, he now wants to open new cages for growing smolts from a non-certified origin. As there is a risk that the smolts from the non-certified process may carry diseases that might spread through the water to the certified production process, Parallel Production is not possible in this case. Producers are expected to have a system in place that prevents the mixing of certified and non-certified products. Certified and non-certified products may be identified visually when cultivars with specific visual differences are produced (e.g. the cultivar of the certified process has another color or shape as the non-certified cultivar). The outcome of both processes should, however, not be mixed. In the case products do get mixed, they are considered as all originating from the non-certified production process. (AF 12.1.1.) The producer's recording system and handling procedures should reflect that the certified and non-certified production processes are always segregated.
