We’ll explore the risks, safety guidelines, and best practices for storing this beloved vegetable.
Perils of Room Temperature Storage
Uncooked corn on the cob should never be left at room temperature for extended periods. The warm and humid environment provides an ideal breeding ground for bacteria, including harmful strains like Salmonella and E. coli. These bacteria can multiply rapidly, causing foodborne illnesses such as vomiting, diarrhea, and fever.
