　　The lifespan of chopsticks is 3 to 6 months. If the chopsticks become discolored, replace them immediately.

　　The survey found that when ordinary chopsticks are used for 3-6 months, their color will become darker or lighter with time and frequency of use. Additionally, the edible paint on the surface of the chopsticks suffers from wear due to frequency of use. Whenever the chopsticks change from when you purchased them, especially the color, they need to be replaced immediately.

　　A change in the color of chopsticks means that the properties of the material itself must have changed. The factors that cause color changes are usually caused by the adhesion of food, detergent and air, and residues in the dining cabinet during use. Long-term accumulation of bacteria is also a major factor in color changes.

　　Smell and take a look to tell whether the chopsticks have expired.

　　When you use chopsticks, you should observe every day whether there are spots, especially mildew, attached to the surface of the chopsticks. Bamboo products and wood products are the favorite living environments for mildew, and as long as the environment is not dry and the humidity content of the material itself reaches a certain level, it only takes one day to form.

　　Expert advice: Once you find mildew on chopsticks, you must stop using them as soon as possible. If there are spots on the chopsticks that are not the original color of bamboo or wood, it means that the chopsticks are likely to have become moldy and deteriorated and cannot be used anymore; if the chopsticks appear damp or bent or deformed, it means that they have been damp or have been left for too long, and may have passed the shelf life; smell it and if there is an obvious sour smell, it is a sign of contamination or expiration and cannot be used anymore.

　　Dry chopsticks before storing them to avoid mold

　　It is understood that at present, the chopsticks used by ordinary people in their homes are mainly made of bamboo and wood, with very few made of metal and other materials. However, the use of these two materials is relatively special. People are usually accustomed to cleaning the chopsticks and then placing them in the chopstick tube or cupboard.

　　After the chopsticks are not completely dried, the humidity is very high, which makes them prone to mold, which has an impact on your health. When using chopsticks, you must ensure that the chopsticks are placed or stored in a dry place to avoid providing an environment for mold growth as much as possible.

　　Expert advice: Boil chopsticks in boiling water for half an hour every week, then place them in the air to dry before use. This can achieve disinfection and effectively and conveniently remove mold in the chopsticks.

　　Buy new chopsticks and wash them thoroughly

　　Experts remind: Chopsticks are easily contaminated with viruses, bacteria and certain chemicals during production and transportation. You can clean the newly purchased chopsticks with tap water first, then wash them with dish soap a second time, and finally put them in a pot and boil them in boiling water for half an hour.

　　In daily cleaning, chopsticks should be thoroughly cleaned. First, rinse the surface of the chopsticks, then carefully rub the chopsticks with detergent, then put them in a disinfection cupboard for disinfection and drying. You can also rinse and drain the water before putting them in the chopstick box.

　　Wash chopsticks, don’t rub them violently

　　Experts point out that the way most families wash chopsticks is very bold: grab a handful of chopsticks, rub them vigorously with detergent a few times, and then rinse them with clean water. In fact, this can easily make the chopsticks, especially the "naked chopsticks" without a protective layer, roughened and produce many small grooves and cracks, which can allow pathogenic microorganisms to remain.

　　Chopstick boxes should be hollow and do not allow water to collect at the bottom, and should be cleaned and disinfected frequently. Do not choose strong acid or alkali detergents to prevent residual chemicals from causing harm to the human body.

　　“Colorful chopsticks have hidden dangers

　　Nowadays, some colorful chopsticks appear in the eyes of consumers. Experts recommend that consumers choose chopsticks that have been brushed with a layer of varnish (raw lacquer) and have a shiny surface, because raw lacquer has national standards. However, "painted chopsticks" have certain safety risks.

　　Because, unlike raw lacquer, the paint on colorful "lacquered chopsticks" is not regulated by national standards. If used improperly, the paint will fall off or decompose at high temperatures. Carcinogens such as heavy metal lead and organic solvent benzene may enter the mouths of consumers, seriously endangering people's health.
