96 views

The shelf life of milk without refrigeration is extremely short, generally lasting only a few hours once it's at room temperature. Without the cold environment of a fridge to slow bacterial growth, milk starts to spoil quickly. In temperatures above 40°F (4°C), milk's bacteria begin to multiply rapidly, making it unsafe to consume. For longer shelf life without refrigeration, consider ultra-high temperature (UHT) treated or powdered milk, both of which are processed to withstand room temperature storage for extended periods.
