there was no widespread practice of not refrigerating eggs in Australia. However, there might have been some confusion or misconceptions around this topic.
In many countries, including the United States, eggs are washed before being sold to remove any potential contamination, but this also removes a protective layer called the "bloom" or "cuticle" that naturally seals the pores of the eggshell. As a result, refrigeration is necessary to prevent the growth of bacteria and to keep the eggs safe for consumption.
In contrast, some European countries, including parts of Europe and the UK, don't wash the eggs before selling them. Instead, they leave the natural protective coating intact. This allows eggs to be stored at room temperature and still be safe to eat for a few weeks.
In Australia, as well as many other countries, eggs are typically sold after being washed and refrigeration is recommended to maintain their freshness and safety. It's possible that individuals or certain regions in Australia might have different habits or beliefs around egg storage, but it's not a widespread practice to not refrigerate eggs in the country. It's essential to follow the guidelines provided on the egg carton or by the local health authorities to ensure proper storage and consumption.
