The 18 ounce, 2,400+ calorie ER Bar is formulated specifically in accordance with the stringent requirements of the US Department of Homeland Security and the US Coast Guard for emergency victims. Ideal for emergency situations, each packet contains six individual 410 calorie rations that are ready-to-eat with no preparation. With a non-thirst provoking formula and a perfect balance of quality ingredients, the ER Bar provides nutrition specifically formulated for disaster victims, including an optimum balance of salt, carbohydrates, protein, fat and enriched with the recommended daily allowance of vitamins and minerals. Food requirements will vary from person to person and may also vary depending upon environmental circumstances (cold weather requires more energy to stay warm, for example). Just one 2,400+ calorie ER Bar can minimally sustain an average person up to three days if necessary, but it’s advisable to evaluate the needs of your family and prepare accordingly. Following a disaster, food supplies may become disrupted, stores closed and power outages could last for days. The US Department of Homeland Security and FEMA recommend stocking a three-day supply of non-perishable food per person to prepare for emergencies. Even canned foods can spoil within 6 months. Get quality food rations that you can count on and store ER Bars in multiple locations for easy access to essential nutrition in an emergency. The special re-sealable package is vacuum sealed and certified by the USCG to maintain a 5-year shelf life. ER bars contain no tropical oils, coconut or nuts which may cause dangerous allergic reactions when no medical aid is available.
