The objective of general surveillance is to identify unforeseen adverse effects of the genetically modified (GM) plant or its use on human health or the environment, which were not anticipated in the environmental risk assessment. Methods and approaches proposed for the general surveillance of a GM starch potato to be cultivated within a closed-loop system will be presented. This system, also referred to as an identity preservation (IP) system, constitutes an important management tool in order to preserve the unique characteristics and the value of the potatoes modified for an increased amylopectin content in the tuber. Elements of the IP system like the farm questionnaire will be used as a basis to collect relevant data on plant growth, characteristics and treatments as well as to record general observations performed by the grower during cultivation and will thus allow for monitoring for any unanticipated or unforeseen effects during cultivation of amylopectin potatoes in the agricultural environment.
