The cash that’s set aside should be enough to cover “the minimum necessary expenses for a period of three days, such as for water, food, medicine, and transportation.”

In March, the European Commission published a preparedness plan that recommended citizens stock three days’ worth of food to ensure supplies in case of emergencies like war or natural disasters.
