The primary concern is the rapid growth of harmful bacteria like Listeria, E. coli, and Salmonella, which can multiply rapidly between 40°F and 140°F (4°C and 60°C), the typical temperature range for raw milk storage. If raw milk is not consumed within the recommended 7 to 10 days, the risk of contamination increases significantly, making it unsafe for human consumption. In fact, the Centers for Disease Control and Prevention (CDC) estimate that unpasteurized milk is 840 times more likely to cause foodborne illnesses than pasteurized milk. To minimize the risk, it’s crucial to purchase raw milk from licensed, regulated sources that follow proper handling and refrigeration procedures, and to always check the expiration date and odor before consumption.

Can the shelf life of raw milk be extended using natural preservation methods?

Extending the shelf life of raw milk is a top priority for dairy farmers and those who consume it fresh from the source. While pasteurization and refrigeration are the traditional methods to prolong milk’s edible lifespan, natural preservation methods can also effectively keep raw milk fresh for a longer period. One such technique is using a process called “raw milk culturing”, where beneficial bacteria like Lactobacillus acidophilus and Bifidobacterium bifidum are intentionally introduced to ferment lactose, creating lactic acid that acts as a natural preservative. This approach maintains milk’s nutritional profile, retains its natural enzymes, and even enhances its flavor profile – as witnessed in aged, cultured cheeses. Additionally, strategies like keeping raw milk in airtight containers away from direct sunlight, and storing it at temperatures between 33°F (0.5°C) and 39°F (3.9°C) can also contribute to its longer shelf life, typically up to 1-3 weeks, while striving to maintain its quality and safety.

Is it safe to drink raw milk that has been left out of the fridge for a short period?
