Though some foods do not expire, but it is advisable not to consume certain foods once they have expired. 

1. Eggs: Eggs contain large amounts of nutrients per calorie. They are a cheap and tasty source of protein. It is no big surprise that they have turned into a breakfast staple; yet in case that you are eating an egg that is past its expiry date, do reconsider. These are the most widely recognized reasons for food-borne illnesses.
2. Meat: Bacteria are common in both pre-packaged meats, and in the pieces you take from your butcher at the market. The listeria bacteria are especially hazardous, as the type of harm it causes can be lethal in most of the cases. From a general outlook, it is best to avoid processed meat.
3. Mixed greens: Mixed greens including spinach, arugula, spring blend, bundled plate of mixed greens lettuce and other veggies do not keep extremely well after their due date. So if their withered appearance and disgusting covering does not turn you off, think about the bacteria and pathogens hiding underneath your sandwich bread.
4. Hay sprouts: It is important that you use them rapidly once you get them, since they tend to be bacteria magnets. Truth be told, hay pulls in a greater number of germs than other vegetables, particularly in case you abandon them unrefrigerated.
5. Clams/oysters: Bad oysters can be fatal. This is based on the type of microscopic organisms that develop in spoiled oysters. It is known as V. vulnificus. It causes an extreme type of food poisoning. V. vulnificus bacteria affects the circulatory system, sending the body into a septic shock.
6. Shrimp: Much like clams and shellfish, shrimps are extremely inclined to bacterial contaminations. It is not to be consumed after a while since it can lead to food poisoning or diarrhea.
7. Crude ground beef: E. coli bacteria are the most basic reason for food poisoning. These bacteria originate from the animal’s digestive system and are available in all hamburger items. In case that the hamburger is prepared and taken care of securely, it will not turn into a problem.
8. Berries: When berries turn sour, they pull in extensive amounts of cyclospora, a kind of bacteria that leads to food poisoning. While this sort of food poisoning is not as harmful as some others, it is something you definitely need to stay away from.
9. Soft cheese: With hard cheeses, similar to cheddar, it is regularly safe to remove the external edges and eat the soft cheese underneath. However, this practice does not reach out to soft cheeses, similar to brie. In case you are discovering mold on the edges of your soft cheese, do not eat it. You may end up with an infection.
10. Chicken: Poultry items, including chicken tend to cause the maximum harm in case that they are not taken care of and cooked properly. Undercooked and old chicken can be very unsafe for health. If you wish to discuss about any specific problem, you can consult a dietitian-nutritionist.
