Usually the wrong was caused by a lack of research. There is more than one company that has faced this same issue, but let's take Nestle for example. 3 Nestle marketed powdered formula to third world countries. Well, babies were dying. It was not Nestle's product that was killing babies.
Powdered formula has to be mixed with water before fed to the baby.
Third world countries do not have an abundant supply of clean water. Nestle lost the trust of its publics because of boycotts promoted by interest groups. Nestle did not address the issue until years later. Nestle worked with the National Association of Infant Food Manufactures to end all supplies of infant formula in developing countries and to be continuously committed to ending free baby food supplies to hospitals of third world countries. This controversy began in the 1980's and the policy for marketing in third world countries was not changed until the 1990's.
