In canning terminology, damage to the side wall of a food can from rough handling during transport, warehousing, or retail display. Dents to the lateral seam or body can compromise the can’s hermetic seal or damage its internal lacquer lining, creating routes for microbial contamination or metal pickup into the food. Quality control inspectors reject cans showing sharp dents, especially near seams, while shallow, smooth dents on the body panel may be acceptable. The term reminds everyone in the supply chain that tins are precision-engineered containers: dropping, throwing, or stacking them carelessly constitutes abuse that can turn safe food into a hazard.
