\u26a0\ufe0f Important information on emergency preparedness<\/p>\n

This guide is intended solely to provide general information on emergency preparedness. It is not a substitute for professional advice<\/strong> from qualified personnel or official recommendations.<\/p>\n

Act immediately in an emergency:<\/strong> always try to contact the emergency services on 112<\/strong>. Official recommendations on crisis preparedness can be found at the Federal Office for Civil Protection and Disaster Assistance (BBK)<\/a>. Last reviewed: June 2026.<\/p>\n<\/div>\n

When the power goes out, the clock starts ticking. The fridge will keep food fresh for another 4\u20136 hours. The freezer will last 24\u201348 hours if it is full and remains closed. After that: everything will go off \u2014 unless you take action.<\/p>\n

These 6 methods will help you keep food fresh for as long as possible, even without electricity.<\/p>\n

Method 1: Preserving<\/h2>\n

Preserving is the oldest and most reliable method of food preservation. Fruit, vegetables, meat and soups are sterilised in preserving jars at high heat and can then be kept for years \u2014 without refrigeration, without electricity.<\/p>\n

Shelf life:<\/strong> 1\u20135 years depending on the contents.
\nRequired:<\/strong> preserving jars, large saucepan, camping stove.<\/p>\n

Method 2: Freezing \u2014 but prepared properly<\/h2>\n

During a power cut: Do not open<\/strong> the freezer. It will keep for 24\u201348 hours if full. Wrap blankets or sleeping bags around it for extra insulation. In winter: Move food to the balcony or into the car (if it\u2019s cold enough).<\/p>\n

Quick tip:<\/strong> When the power cut begins, use up the contents of the fridge immediately (as they spoil more quickly) and leave the freezer untouched.<\/p>\n

\n

Method 3: Dehydrating \/ Drying<\/h2>\n

Dried food keeps for months to years without refrigeration. Meat (jerky), fruit, vegetables, herbs \u2014 all of these can be dried.<\/p>\n

Without electricity: In summer, dry in direct sunlight (on a clean cloth), or over a camping stove on a low heat.<\/p>\n

Shelf life:<\/strong> Dried fruit 6\u201312 months, dried meat 1\u20132 months.<\/p>\n

\n

Method 4: Pickling in salt or vinegar<\/h2>\n

Salt and vinegar effectively inhibit bacterial growth. Cucumbers, onions, meat, fish \u2014 everything can be pickled.<\/p>\n
