The Dangerous History of Unregulated Milk
Before widespread regulation and the practice of pasteurization, milk was a common vector for dangerous diseases. The 19th and early 20th centuries saw frequent milk-related outbreaks of tuberculosis, typhoid fever, and scarlet fever, which were particularly devastating to infants and children. The conditions of early urban dairy farms, including feeding cows waste products like 'distiller's swill' and unsanitary transport, contributed to high rates of contamination. This led to a public outcry and the rise of the 'certified milk' movement, which promoted cleaner production practices and laid the groundwork for future regulation.
The Rise of Pasteurization and Federal Oversight
The process of pasteurization, developed by Louis Pasteur in the 19th century, proved to be a highly effective method for killing harmful bacteria in milk by heating it to a specific temperature. While debated at first, its adoption accelerated throughout the 20th century as a key public health measure. The federal government's involvement began in earnest with the Pure Food and Drug Act of 1906, but more specific dairy regulations followed. The most significant regulatory framework was the Grade "A" Pasteurized Milk Ordinance (PMO), first introduced in 1924, which set standards for sanitation and pasteurization that state health departments could voluntarily adopt.
The Interstate Ban: Why 1987?
The final federal rule prohibiting the interstate sale of raw milk in final package form was enacted in 1987 by the Food and Drug Administration (FDA). This ban was the culmination of regulatory efforts that began earlier in the decade to stop the cross-border distribution of a product deemed unsafe for direct human consumption. A federal judge’s ruling in early 1987 further solidified the FDA's position, mandating the ban due to the significant health risks posed by pathogens like Salmonella and Listeria. This federal action was a response to recurring outbreaks tied to raw milk, emphasizing the inherent danger of unpasteurized dairy regardless of sanitary conditions.
The Confusing Patchwork of State Laws
Even with a federal ban on interstate commerce, the legality of raw milk sales within state borders is determined by individual states. This has resulted in a complex and often contradictory set of laws. Some states, like California and Arizona, permit retail sales of raw milk under certain conditions and with proper permits. Others, like Iowa and North Dakota, have passed more recent laws to expand access, often limiting sales to on-farm transactions. A significant number of states, however, still ban raw milk sales outright or only allow acquisition through "cow-share" agreements, where individuals purchase a share of a dairy animal to receive its milk.
Raw Milk vs. Pasteurized Milk: A Comparative View
| Feature | Raw Milk | Pasteurized Milk |
|---|---|---|
| Safety Risk | High; risk of contamination with dangerous pathogens like E. coli, Salmonella, and Listeria. | Low; pasteurization process kills harmful bacteria, significantly reducing risk of foodborne illness. |
| Regulation | Varies significantly by state; federal ban on interstate sales. | Nationally regulated under the Grade “A” Pasteurized Milk Ordinance for interstate commerce. |
| Nutritional Content | Proponents claim higher nutritional value; however, scientific evidence shows no meaningful difference in nutrients compared to pasteurized milk. | Nutrient content is comparable to raw milk; often fortified with Vitamin D. |
| Taste/Flavor Profile | Advocates claim a richer, more complex flavor. | Standardized flavor profile; taste is consistent due to processing. |
| Beneficial Microbes | Contains a wider array of bacteria, though not all are beneficial and pathogens can be present. | Beneficial microbes for fermentation (like in yogurt) are added after pasteurization. |
The Ongoing Debate and Modern Trends
The debate over raw milk continues, fueled by both advocates and public health officials. Proponents champion raw milk for its perceived health benefits and natural state, arguing that with proper sanitation, risks can be minimized. They point to studies suggesting a link between raw milk consumption in farming environments and lower rates of allergies and asthma, although health officials maintain these links are not directly proven and environmental factors are likely significant.
However, health agencies like the FDA and CDC remain steadfast in their warnings, citing a disproportionately high number of foodborne illness outbreaks linked to raw milk consumption. Despite these warnings, the demand for raw milk persists, leading to new intrastate legislation in states like Iowa and North Dakota. The rise of the "buy local" food movement and farm-to-consumer relationships has also complicated regulatory enforcement, as these transactions often fall outside the purview of federal interstate commerce laws.
The Role of Public Health Agencies
The FDA, CDC, and state health departments consistently warn against the consumption of raw milk. The core of their argument is that raw milk, no matter how carefully it is produced, carries an inherent risk of containing dangerous pathogens. These agencies stress that certain vulnerable populations, including children, pregnant women, the elderly, and immunocompromised individuals, face a particularly high risk of severe illness from raw milk. From 1998 through 2018, there were 202 outbreaks linked to raw milk, resulting in 2,645 illnesses. These outbreaks serve as a powerful reminder of the risks that led to the initial federal regulations.
Conclusion
In summary, raw milk did not become entirely illegal at a single national moment in the US. Instead, a federal ban on its interstate sale was implemented in 1987, effectively stopping its widespread commercial distribution. This followed decades of public health reforms driven by concerns over foodborne diseases. Today, the legality of raw milk is a state-by-state issue, with laws ranging from retail legality to complete bans, all while federal warnings about health risks persist. The ongoing debate highlights the tension between consumer choice and public health regulations. The legal landscape of raw milk is a reflection of evolving science, differing philosophies on food freedom, and the enduring legacy of 20th-century public health crises.
Key Federal and State Milestones
- 1906: Pure Food and Drug Act enacted, representing an initial step toward federal food regulation.
- 1924: US Public Health Service introduces the Standard Milk Ordinance, a precursor to the modern PMO.
- 1965: Standard Milk Ordinance transitions into the Grade "A" Pasteurized Milk Ordinance (PMO).
- 1973: FDA adopts a regulation requiring all milk sold in interstate commerce to be pasteurized.
- 1987: FDA officially prohibits the interstate sale and distribution of raw milk for direct human consumption.
- Present: Legal landscape remains a state issue for intrastate sales, with varying regulations.

Conclusion
The question of when raw milk became illegal in the US has a layered answer. There was no single moment it was outlawed nationwide. The crucial step was the 1987 FDA ban on interstate sales, a decisive public health measure following decades of accumulating evidence and regulatory action against milkborne illnesses. While some states have carved out exceptions for intrastate sales, the federal stance remains clear due to safety concerns. This has created a dynamic legal and cultural landscape, where the push and pull between safety and personal choice continues to define the availability of raw milk across the country.
