Can salt and pepper packets be reused?

Salt and pepper packets can be reused only if they are unopened because unopened packets maintain their integrity and have not been exposed to contamination from other food items, hands, or environmental factors. Once a packet is opened, it becomes susceptible to bacteria and other contaminants, making it unsafe to reuse. Additionally, opened packets can also lose their freshness and flavor. Therefore, the practice of reusing unopened salt and pepper packets is acceptable, as they are sealed and protected from external contaminants, ensuring their safety for consumption.
