International Association for Food Protection

In the early 20th century, an increasing number of cities and states in the US passed policies to ensure safety of milk. The laws were a response to the food industry's deception at that time. There were types of alteration in milk products on the market, such as water-dilution or adding butter or cheaper substitutes. In addition, spoiled milk is danger to health: infant mortality rate was lower in cities that had monitored milk production and sale. The association was established in 1911 based in Milwaukee, Wisconsin, and there were 35 members. One of the members was from Canada, and one from Australia; the rest were from the US. According to the Association's constitution, an object is to develop "uniform and efficient inspection of dairy farms, milk establishments, milk and milk products" by "men who have a thorough knowledge of dairy work." The object reflects the historical context when the association was born.

In 1923, the Association deemed pasteurization as necessary for processing milk products, and endorsed pasteurization as the only adequate safeguard for milk supplies. US Public Health Service's annual report on milk-borne outbreaks has been decreased from 40–60 per year in the 1920s to about 20 per year after World War II.

In the 1960s, the association had expanded its vision on food protection from milk safety. As the president of the association pointed out in 1960: "Today, we sanitarians must be equipped to deal with problems extending throughout the entire range of environmental health. We must solve problems of waste disposal, insect and rodent control, air pollution, housing, radiological poisoning and many others. Additionally, with more Americans eating out more often than ever before, the food service industry has become an area of responsibility such as would have been impossible for our founding Members to imagine. Recently the packaging of prepared foods of the 'heat and eat' variety has developed as a rapidly expanding industry that poses new sanitation problems for you to solve." The name of the association was changed after a mail ballot in members at large in response to the expanded scope of the association, the International Association of Milk, Food and Environmental Sanitarians (IAMFES).
