Differences with pasteurized milk
The main differences compared to pasteurized milk are that both harmless bacteria and any pathogenic microorganisms remain alive in raw milk; the flavor can be more intense and variable; and the shelf life is much shorter. In pasteurized milk, however, controlled heating eliminates most of the harmful microorganisms, preserving its nutritional properties almost unchanged.
From a health perspective, the risk of raw milk doesn't depend on its "natural" nature, but on potential contamination during milking, collection, or storage. For this reason, health authorities recommend boiling it before consumption.

How to avoid dangers
- Always bring raw milk to a boil before drinking. In Italy, vending machines often display the warning "boil before consumption."
- Store immediately in the refrigerator at ≤4°C and consume within 1–2 days.
- Use clean, tightly closed containers.
- Avoid interrupting the cold chain during transport.
- Do not give raw milk to small children, the elderly, pregnant women, or immunocompromised people: these are the groups most at risk of complications.
- If the milk has an abnormal odor, color, or taste, do not consume it.
- Buy it only from authorized producers who comply with veterinary and hygiene controls.
The possible benefits
Those who consume raw milk often appreciate:
- the most intense and “fresh” taste,
- the minor industrial processing,
- the link with local production and short supply chains.
From a nutritional point of view, however, the benefits compared to pasteurized milk are more limited than is often believed.
In raw milk the following remain intact:
- some natural enzymes,
- part of the microbial flora,
- heat-sensitive vitamins in slightly larger quantities.
