How long can perishable foods be left out at room temperature?

Perishable foods, such as meat, dairy, and other items that require refrigeration, can be left out at room temperature for no more than 2 hours. This is crucial because the risk of bacterial growth significantly increases once these foods are exposed to temperatures between 4°C (40°F) and 60°C (140°F), often referred to as the "danger zone."

After 2 hours, the potential for harmful bacteria to multiply to dangerous levels rises sharply, increasing the risk of foodborne illness. This guideline is supported by food safety authorities and is essential for maintaining food safety in both home and commercial kitchens. Following this rule ensures that food remains safe for consumption and reduces the risk of food poisoning associated with improperly handled perishable items.
