A study of market milk conditions in Iowa by the market milk laboratory of the dairy department at Iowa State College reveals the fact that the state has a real milk problem to deal with.

In the cities and towns in which the investigation was carried on, the results indicate these facts:

The milk and cream, whether raw or pasteurized, commonly contains excessive numbers of bacteria, altho samples without excessive numbers were sometimes found.

The presence of large numbers of bacteria in pasteurized milk and cream indicates that the heat exposure used in some plants is too low, altho improper handling after pasteurization is also partly responsible for this condition.
