Which food is considered the least shelf stable?

Fresh meats are considered the least shelf stable due to their high moisture content and perishable nature. Unlike canned goods and dried pasta, which can be stored for long periods without refrigeration, fresh meats must be kept at proper temperatures to prevent spoilage and the growth of harmful bacteria. If left at room temperature, fresh meats can deteriorate quickly, making them unsafe to eat. Proper handling and storage, including refrigeration, are crucial to ensuring their safety and quality, which emphasizes their vulnerability compared to other food items that have longer shelf lives.
