Food, Water, and Sanitation
Build a pantry you use and keep safe water on hand.

Start with foods you already eat
Plan several meals that can be eaten without heat or added water. Include a manual opener, foods that fit household allergies and diets, and any infant supplies. Canned food is often ready to eat, while freeze-dried or dehydrated meals may need extra clean water. Date supplies and use the oldest first.
Store and treat water safely
Store commercially bottled water or use clean food-grade containers following CDC instructions. Follow local advisories for boiling or treatment. Filters vary in what they remove. Boiling and ordinary disinfection cannot make water contaminated with fuel or toxic chemicals safe. Use another source when advised.
Plan hygiene and cooking
Set aside soap, trash bags, and sanitation supplies. Follow local health guidance when sewer or water service fails. Use camp stoves and grills only outdoors and follow instructions for their fuel. Plan no-cook options for days when outdoor cooking is impractical.
