Where damaged cargo taints other cargo, the resultant loss is known as sympathetic damage. If the original damage was occasioned by an insured peril without any intervening cause then the sympathetic damage is covered by the policy. Goods liable to cause this type of damage include: hides and skins, certain cheeses, guano and carbon disulphide.
