Any disruption or deviation in the temperature-controlled supply chain that compromises product integrity, safety, or quality. Common causes include equipment malfunction, power outages, improper handling, inadequate packaging, or delays during transfer points. In frozen foods, even brief temperature excursions above -12°C can trigger microbial growth, texture degradation, and nutritional loss. The financial impact includes product write-offs, insurance claims, brand damage, and potential liability for foodborne illness. Prevention requires redundant systems, real-time monitoring, rapid response protocols, and proper insurance coverage. Cold chain failures cost the South African food industry millions annually in spoiled inventory.
