Many people know that toothbrushes should be replaced regularly, but it is common to use a pair of chopsticks for a few years. It is understood that many families have used a pair of chopsticks for a short period of one or two years, and the length is far more than that. They generally believe that there is no need to change chopsticks if they are not bad, but experts say that chopsticks should not be used for more than half a year, otherwise it may cause health problems.
In addition to chopsticks, what are the shelf life of household items that are easily overlooked? What impact will the daily necessities of the daily necessities be? What issues should I pay attention to when purchasing?
The reporter investigated a large number of daily necessities and unqualified shelf life. Most of the people were overdue for several days. The reporter visited dozens of supermarkets in Fuzhou, and found that most of the chopsticks did not indicate the shelf life. Only a few of them were marked with a shelf life.
During the visit, the reporter interviewed 20 consumers randomly, and more than 80% of the respondents said that they had never heard of the shelf life of chopsticks. Most people said that they only changed their chopsticks once a year, and they all changed during the Chinese New Year, mainly to resign the old and welcome the new. Some respondents even said that it is not clear how often to change chopsticks, only when chopsticks are broken or moldy.

In addition, due to the use The frequency causes the edible paint on the surface of the chopsticks to be worn out.†According to Ling Meiying, an engineer from the Quality Supervision Bureau of the Quality Supervision Bureau of the Provincial Quality Supervision Bureau, as long as the chopsticks change compared with the purchase, especially the color, it needs to be replaced immediately.
According to reports, the color of the chopsticks changes, indicating that the nature of the material itself must change. The factors that cause color change are usually caused by the adhesion of food, detergent and air, and residues in the dining cabinet during use. "I personally think that the long-term accumulation of bacteria is also the main factor in the color change." Ling Meiying said.
2 smell and smell to see if the chopsticks expired expert advice, everyone when using chopsticks, every day to observe, whether the surface of the chopsticks attached to spots, especially mildew. "Bamboo products and wood products are the favorite living environment for mildew, and as long as the environment is not dry, the moisture content of the material itself reaches a certain level, it only takes one day to be produced." Ling Meiying believes that once the chopsticks are found Mildew spots must not be used for the first time.
