What is raw milk?
Raw milk is milk has not undergone pasteurization, a process that involves heating the milk to kill harmful bacteria. Proponents believe that raw milk retains more nutrients and beneficial bacteria compared to pasteurized milk.
Importance of proper storage
Proper storage is crucial to maintaining the freshness and safety of raw milk. Incorrect storage conditions can lead to bacterial contamination and spoilage.
Overview of factors affecting raw milk shelf life
Several factors can influence how long raw milk lasts, including temperature, exposure to light, and bacterial contamination. Understanding these factors is key to preserving the quality of raw milk.
Factors Impacting Raw Milk Shelf Life
Temperature
How long does raw milk last depends on temperature. Temperature plays a significant role in determining the shelf life of raw milk. Storing raw milk at a consistent temperature below 40°F (4.4°C) is crucial to prevent bacterial growth and spoilage.
Exposure to light
Exposure to light can accelerate the breakdown of nutrients in raw milk and lead to off-flavors. It’s best to store raw milk in opaque containers to protect it from light exposure.
Bacterial contamination
Bacterial contamination is a primary concern when it comes to raw milk. Proper handling and storage practices can help minimize the risk of contamination and extend the shelf life of raw milk.
Signs of Spoiled Raw Milk
Change in texture
Spoiled raw milk may develop a clumpy or curdled texture, indicating that it has gone bad.
Off-putting odor

The presence of mold on the surface of raw milk is a clear indication that it has spoiled and should be discarded.
How Long Does Raw Milk Last?
Refrigeration
Store raw milk in the coldest part of the refrigerator, away from the door, to maintain freshness. Make sure the temperature is consistently below 40°F (4.4°C). This can extend its shelf life for 7-10 days
Freezing raw milk
Freezing raw milk can extend its shelf life for several months. However, be aware that freezing may alter the texture and flavor of the milk slightly.
Pasteurization
While pasteurization is not required for raw milk, it can help reduce the risk of bacterial contamination and increase the shelf life of the milk.
Changes in Raw Milk:
Over time, raw milk naturally turns sour due to the presence of bacteria. This pickling process doesn’t mean it’s gone bad, but it does change the flavor. Some of you may actually prefer the taste of sour raw milk.
Health Risks Associated with Consuming Spoiled Raw Milk

Allergies
Some individuals may be allergic to certain bacteria present in raw milk, leading to allergic reactions upon consumption.
Importance of proper handling and consumption
Proper handling and consumption practices are essential to reduce the risk of consuming spoiled raw milk. Always check for signs of spoilage before consuming raw milk.
Summary
In conclusion, the shelf life of raw milk can vary depending on several factors. Proper storage, monitoring for signs of spoilage, and understanding health risks associated with consuming spoiled raw milk are crucial for safe consumption.
