Blackheart is a physiological disorder resulting in necrosis and cavitation of central tissues of potatoes. It does not occur in crops from the field and is therefore a particular problem for GB where a large proportion of the crop is marketed from store. Blackheart is a particular problem for the fresh potato industry because QC procedures cannot adequately control the defect which is undermining consumer confidence. Blackheart is estimated to account for 25-30% of consumer complaints.
