In 1859, the first milk inspector was appointed in Boston. In 1864, Boston prohibited the use of milk from diseased cows. As early as 1848, European veterinarians suspected that bovine tuberculosis was transmissible. The first city to inspect dairies may have been Newark, New Jersey, in 1882, and regular bacteriology examination of milk was first undertaken in Montclair, New Jersey, in 1900. Chicago, in 1908, was the first city to require pasteurization of milk except that from tuberculin attested cows.
