New York Requires Pasteurization of Milk
As cities began to industrialize, milk production and distribution became more unsanitary. This was the cause of many milkborne diseases, which were commonly fatal. Unsanitary milk caused illnesses such as typhoid fever, scarlet fever, and diphtheria. In 1910, the New York City Board of Health issued an order requiring the pasteurization of milk in hopes of reducing pathogens and diseases in milk. Other states followed throughout the next decade.
