Manufacturers have a moral obligation under the principle of due care to protect consumers from foreseeable risks in their products. They must exercise care in designing, producing, and marketing products to minimize risks and ensure products do not harm consumers. This replaces the doctrine of caveat emptor with an expectation that manufacturers take responsibility to ensure product safety through practices like quality control, packaging, labeling, and warnings. However, due care does not specify costs to eliminate risk or who pays for unforeseen injuries.
