Emergency food supplies are non-perishable food items that are stored for use during unexpected situations, such as natural disasters or power outages. These supplies typically include canned goods, dried fruits, grains, and freeze-dried meals, which can last for long periods without refrigeration. Having a stock of emergency food supplies ensures that individuals and families can sustain themselves when access to regular food sources is disrupted. It is recommended to have enough food to last at least three days, and to periodically check and rotate supplies to maintain freshness and safety.
