Egg storage and preparation: Expert advice on safety and nutrition

Food experts recommend storing eggs in the refrigerator to ensure maximum freshness and safety. While eggs are often left on kitchen countertops, the refrigerator provides the stable, low temperatures necessary to slow the growth of bacteria such as salmonella. Because eggshells are not completely airtight, temperature fluctuations can cause condensation on the shell, which may facilitate bacterial penetration. In Germany, eggs are typically not washed, allowing them to retain a natural protective layer, but refrigeration remains the best practice once they are brought home.

Regarding preparation, the nutritional value of eggs remains high, but the method of cooking affects calorie and fat intake. Methods such as boiling or poaching are considered healthier as they do not require additional oils or butter. When frying eggs, the type of fat used significantly impacts the energy content. For environmental and animal welfare reasons, experts suggest choosing organic eggs from associations like Bioland, Naturland, or Demeter, as well as opting for regional products to reduce CO2 emissions from transport.
