Food-supply disruption: build a modest buffer

Build the buffer through normal shopping

• Start with food your household already eats and replace it before its use-by or best-before guidance becomes a problem.
• Include ready-to-eat tins or pouches, a manual tin opener, cereal, nut or seed products where safe, long-life milk and food for pets.
• Include food that needs little or no water and no cooking.
• Plan around allergies, cultural needs, swallowing needs, diabetes and other health requirements.
• Add one or two items at a time rather than clearing shelves or buying specialist survival food.

Plan for cooking and refrigeration failure

A closed fridge usually keeps food cold for about four hours. A full freezer can stay cold for about 48 hours, or about 24 hours if half full. These are planning figures, not a guarantee. Temperature, opening and appliance condition matter.

• Eat safe perishable food first when the outage duration becomes clear.
• Use a fridge thermometer and follow official food-safety advice.
• Keep a no-cook meal option for each person and a safe way to prepare infant feeds.

Shortage messaging

Use the term food-supply disruption unless an authoritative assessment uses stronger language. Do not amplify unverified scarcity claims because panic buying can create the very gaps people fear.
