How long can milkshakes generally sit out before they are no longer fresh?

Milkshakes typically can sit out for up to 2 hours before they are considered no longer fresh. This timeframe is based on food safety guidelines which generally recommend that perishable items should not be left at room temperature for more than two hours. Beyond this period, the risk of bacterial growth increases significantly, making it unsafe for consumption. This is especially important for milkshakes, which contain dairy products that can spoil quickly. Keeping the milkshake within this 2-hour window ensures that it remains safe and retains its quality for customers.
