The main focus of the published reports seems to be on intestinal colic, intestinal irritation, intestinal bleeding, anemia, allergic reactions in infants and children as well as infections such as salmonella. More ominous is the fear of viral infection with bovine leukemia virus or an AIDS-like virus as well as concern for childhood diabetes. Contamination of milk by blood and white cells as well as a variety of chemicals and insecticides was also discussed. Milk is a maternal lactating secretion, a short term nutrient for new-borns. Nothing more, nothing less.
Nursing is provided by nature only for the very youngest of mammals.
It is only humans, who continue the intake of milk, even after the natural-state has stopped providing it. The author mentions milk related problems of bacterial contamination - i.e. Salmonella, E. coli, and staphylococcal infections. In the old days tuberculosis too was a major problem caused by raw milk consumption. A study from UCLA showed that over a third of all cases of salmonella infection in California, 1980-1983 were traced to raw milk. Another example he gives is that in England and Wales where raw milk is still consumed, there have been outbreaks of milk-borne diseases.
