The expiration date before opening and storage details are indicated on the pickled eggs containers. After opening, under optimal conditions, which means keeping the jar in a fridge at 4 degrees Celsius, the eggs can be consumed for about 1 month if you follow this storage tip: No Fingers in the Jar! Always use clean and dry utensils to serve the condiment. This prevents contamination of the jar’s content. Using an unclean utensil can shorten the product’s shelf life. Hence, it’s difficult to guarantee a consumption date after opening. For more tips on safe food storage practices, visit the following Health Canada webpage: Health Canada Food Storage Tips
