What is Real Milk?
The terms "real milk," "farm fresh milk," and "raw milk" are all used to refer to milk that has not been heated in the pasteurization process. But the terms encompass much more! Both farmers and consumers generally use these terms to refer to milk that has not been pasteurized AND:
- has intact cream particles. In other words, it hasn't been homogenized, and the cream rises to the top. You can see how much (or how little) cream is in your milk!
- is from cows and goats raised on pasture, whether they are 100% grass-fed or supplemented with grain.
- is from family farmers, not factory farms.

Safety of Raw Milk
***Note: Scientific studies are listed at the end of the page
• EXCELLENT SAFETY RECORD IN TEXAS: Raw milk has an excellent safety record in Texas. According to the CDC, between 1998 and 2008, there were only two reported cases of illness from raw milk. In contrast, during the same time period, there were 465 illnesses reported just from raw oysters. In fact, there were over 12,000 foodborne illnesses reported in Texas in that time period (not including multi-state outbreaks), traced to such foods as strawberries, mangos, ice cream, cake, beans, lettuce salads, salsa, cheeses, pot pie, chicken salad, hot dogs, deli meats, and beef brisket. Any food carries some risk of foodborne illness, but as shown above (see Existing Regulations, below), licensed raw milk farmers take extensive precautions to ensure the safety and quality of their product.
• OTHER STATES: Sales of raw milk are legal in more than half of the states. Ten states allow the sale of raw milk in grocery stores, which would not be allowed under HB 46.
• PROTECTIVE COMPONENTS OF UNPROCESSED MILK: Raw milk contains numerous components that assist in:
- Killing pathogens in the milk (lactoperoxidase, lactoferrin, leukocytes, macrophages, neutrophils, antibodies, medium chain fatty acids, lysozyme, B12 binding protein, bifidus factor, beneficial bacteria);
- Preventing pathogens from being absorbed across the intestinal wall (polysaccharides, oligosaccharides, mucins, fibronectin, glycomacropeptides, bifidus factor, beneficial bacteria); and
- Strengthening and modulating the immune system (lymphocytes, immunoglobulins, antibodies, hormones and growth factors).
Note that breast milk is raw. The safety and health benefits of breast milk have been well documented.
• LOSS OF PROTECTIVE COMPONENTS DUE TO PASTEURIZATION: Many of these anti-microbial and immune-enhancing components are greatly reduced in effectiveness by pasteurization.
• MODERN ADVANTAGES IN RAW DAIRY PRODUCTION: Compared to 50 years ago, dairy farmers today can take advantage of many advancements that contribute to a much safer product, including rotational pasture grazing, milking machines, effective cleaning systems, and refrigeration. Milk and herd disease testing techniques are also more thorough than when pasteurization became commonplace.
Health Benefits of Raw Milk
• BENEFITS IN HUMAN STUDIES: In early studies involving humans, raw milk was shown to help protect against infection, rickets, and TB; and children receiving raw milk had better growth than those receiving pasteurized milk.
• BENEFITS IN ANIMAL STUDIES: In an early animal study, animals fed raw milk had better growth, less anemia, fewer signs of anxiety and stress, and fewer signs of nutrient deficiency than animals fed pasteurized milk.
• ASTHMA AND ALLERGIES: Several recent studies in Europe have found that drinking “farm” (raw) milk protects against asthma and allergies.
• RAW HUMAN MILK: Infants and premature babies on pasteurized human milk did not gain weight as quickly as those fed raw human milk; problems were attributed to pasteurization’s destruction of lipase. In another study, neonates given raw human milk had a markedly lower incidence of infection than those who received pasteurized human milk and formula.
• LACTOSE INTOLERANCE: In a survey of milk drinkers in the state of Michigan, over 80% of those advised by a healthcare professional that they were lactose intolerant were able to consume raw milk without problem.
• POSITIVE TESTIMONIALS: There are hundreds of testimonials involving reversal of failure to thrive in infants; allergies, asthma and behavior problems in children; and digestive disorders, arthritis, osteoporosis and even cancer in adults.
• NUTRIENTS RETAINED IN RAW MILK:
Vitamin A: Beta-lactoglobulin, a heat-sensitive protein in milk, increases intestinal absorption of vitamin A. Heat degrades vitamin A.
B Vitamins: Significant percentages of Vitamins B6, B12, thiamin and folate are destroyed by heat treatment, although the specific percentages found vary from study to study. In addition, the folacin-binding protein in raw milk is rendered ineffective during pasteurization and processing.
Vitamin C: Heating leads to a loss of Vitamin C in pasteurized milk. “Without doubt, the explosive increase in infantile scurvy during the latter part of the 19th century coincided with the advent of use of heated milks and proprietary foods. … Hess [a pediatrician] was able to effect a cure for scurvy by providing raw milk or orange juice or potatoes.”
Vitamin D: Vitamin D is present in milk in protein-bound form, which may be lost during pasteurization.
Economic Benefits of Raw Milk
- Direct farm-to-consumer sales of raw milk can mean the difference between a net loss on the farm and the ability to provide a reasonable income for the farm family. Below are numbers drawn from actual Texas dairy farmers. These numbers do not cover the full range of potential situations, but provide a sample of the real-world economics of dairy.
Every $1 earned on the farm equates to $5-$7 for the local community. By providing a fair income for rural dairy farmers, Grade A sales of raw milk can help our struggling rural economies.
CONVENTIONAL DAIRY FARM
• Cost of production:
100-cow dairy: $1.50/gallon
• Price for milk sold for pasteurization: $1.13/gallon (current price) to $2.19/gallon (2008 high price)
• Net: ranges from 33 cents/gallon loss to 69 cents/gallon profit
Price is based on market forces outside the farmers’ control. While consumers pay $3 to $6.50 for a gallon of pasteurized milk, farmers see only a small percentage of that money.
In 2002, dairy farms in the U.S. went out of business at the rate of 16 farms per day. Dairy farms are currently facing a crisis.
DIRECT SALES OF RAW MILK
• Cost of production:
100-cow dairy: $1.64-$2.36/gallon
10-cow dairy: $9/gallon
30-goat dairy: $8.50/ gallon
Plus capital investment in milking barn that meets Grade A Standards: $40,000 and higher
• Price for raw milk sold directly to consumers: $5/gallon to $10/gallon for raw cow’s milk; up to $14.50/gallon for raw goat’s milk
• Net: ranges from $1/gallon to $6/gallon profit
Price is not subject to typical market fluctuations, but is generally based on factors within the farmers’ control, such as the breed of cow and extent of pasture grazing. The farmer captures the full retail value.
