Milk spoils at room temperature much faster than when refrigerated. Typically, milk left out at room temperature will begin to spoil within two hours. This timeframe drops in hotter environments. Always smell and visually inspect milk before consuming if it's been out for any period. To prolong its shelf life, always store milk in the refrigerator, preferably at temperatures between 32°F and 40°F (0°C to 4°C), and never leave it out for long periods.
