Nutrition companies face legal conflict with parents over intestinal disease in infants linked to their products.

Nutrition companies face legal clash with parents over cause of intestinal disease in infants; disease kills hundreds in US each year, impacting two multinational corporations' stock prices. Chance Dean, a premature baby, lived 25 days and his tragic story sparked the high-stakes legal conflict. Chance's mother opted for human breast milk from donor banks for her son, but doctors transitioned him to a formula for premature, low-birthweight infants. The companies deny any published study linking their products to the disease, but parents argue the issue is critical.
