Can eating pickled artichoke hearts after due date hurt you?

Eating pickled artichoke hearts after their due date may not necessarily harm you, but their quality, flavor, and texture could deteriorate. If the jar has been properly sealed and stored, they may still be safe to consume, but you should check for signs of spoilage, such as an off smell, mold, or unusual texture. Always use your best judgment and err on the side of caution if you have any doubts about the food's safety.
