Chicken Neck 

The chicken neck is a part that many people enjoy because of its crispy skin, but few know that it is also where many lymph nodes are concentrated. Lymph nodes are immune organs that filter toxins and bacteria from the chicken's body. Therefore, when eating the chicken neck, you may inadvertently consume a significant amount of these toxins. To ensure your health, it is advisable to limit eating chicken necks or remove the skin during preparation.

Chicken Tail

The chicken tail, known as "phao câu," is where many oil glands are located and serves as an excretory organ for waste. As a result, it is prone to parasitic infections, bacteria, and environmental toxins. Despite its rich, fatty flavor, this part is not recommended for frequent consumption due to the potential health risks it may pose.

Chicken Gizzard

The chicken gizzard is the digestive organ of the chicken, where food is ground before being digested. Although it is a popular dish, the gizzard is prone to holding onto dirt and bacteria due to direct contact with undigested food. If you wish to enjoy this part, it is essential to clean it thoroughly and cook it completely to ensure safety.

Chicken Lungs

The lungs are part of the respiratory system and are prone to accumulating bacteria, parasites, and toxins from the chicken’s living environment. Even when the chicken lungs are cooked at high temperatures, the risk of bacteria and parasites remaining is still quite high. Therefore, many nutrition experts recommend removing this part during preparation.
