In 1977, a campaign was launched against Nestle to protest unethical marketing of baby formula in developing countries. Company employees (often dressed like health-care workers) went to hospitals and health clinics to counsel women on formula use--ignoring the proven advantages of breast milk, formula's astronomical cost for Third World families and the fact that many women had only contaminated water for preparing formula, thus starkly increasing a baby's risk of contracting life-threatening diarrhea.
