It's not accurate to say that people in Canada (or other similar regions) don't refrigerate eggs. In fact, the vast majority of people in Canada and the United States, as well as many other countries, do refrigerate eggs. Refrigeration is the standard practice recommended by food safety authorities in these regions.
The reason for refrigerating eggs is to help reduce the risk of foodborne illnesses, particularly the growth of bacteria like Salmonella. Refrigeration slows down the growth of harmful bacteria that may be present on the eggshell or inside the egg. It is an essential step to maintain egg freshness and safety.
However, you may have heard about practices in some European countries where eggs are often sold at room temperature, and people don't refrigerate them. This difference in approach is due to the way eggs are processed and handled in those regions. In the United States, Canada, and some other countries, eggs are washed and sanitized before being sold, which removes the natural protective coating called the "bloom" from the eggshell. This increases the risk of contamination, making refrigeration necessary.
In contrast, in some European countries, eggs are not washed before sale, and they retain the natural protective coating. This coating helps to keep out bacteria and moisture, making refrigeration less critical. Instead, European eggs are often stored at room temperature, and consumers are advised to use them relatively quickly.
It's essential to follow the guidelines and recommendations provided by local food safety authorities. If you are in a region where refrigeration of eggs is recommended, it's best to store them in the refrigerator to ensure their freshness and safety. If you are in a region where eggs are commonly sold at room temperature, be sure to use them within a reasonable time frame and follow local food safety practices.
