No, unrefrigerated milk is generally not safe to drink, especially if it has been left out for an extended period.
Understanding the Risk
Milk is a perishable food that can quickly become a breeding ground for harmful bacteria when left at room temperature. These bacteria can cause food poisoning, leading to symptoms like nausea, vomiting, and diarrhea.
Time is of the Essence
The key factor determining whether unrefrigerated milk is safe to drink is how long it has been left out. According to the FDA, milk should not be consumed if it has been left unrefrigerated for more than two hours. This guideline is crucial for minimizing the risk of bacterial growth.
Practical Guidelines:
- Refrigerate Promptly: Always store milk in the refrigerator immediately after use.
- Two-Hour Rule: If milk has been left out at room temperature for more than two hours, discard it to avoid potential health risks.
- Avoid Unrefrigerated Milk: Do not drink milk that has been left out at room temperature for an unknown amount of time. When in doubt, throw it out.
- High Temperatures: In hot temperatures, the "safe" window is reduced, milk should be refrigerated within 1 hour.

Conclusion
To ensure your safety, always refrigerate milk promptly and avoid consuming it if it has been left out for more than two hours.
