Why You Should Avoid Water Glassing Eggs For Long-Term Storage
The FDA does not recommend water glassing eggs for long-term storage due to risks of salmonella and botulism, which can lead to food poisoning.
Water glassing involves storing eggs in alkaline solutions like sodium silicate or calcium hydroxide in jars or containers and placing them in a cool, dark place.
Beyond the risk of salmonella, there's a concern that the lime water could become a breeding ground for the bacteria that causes botulism and penetrate the porous shells.
Modern science has found that botulism can even be present in the soil where chickens are raised, which is why it's vital to wash eggs before any form of preservation.
