disposable chopsticks in the family can also be reused and cleaned after each use. Chopsticks, whether disposable or commonly used at home, can't be used for too long. Generally, it is better to replace them half a month to one month, because the micropores of chopsticks are easy to breed all kinds of bacteria and produce toxins. If discoloration such as blackening is found, it should also be discarded.
The shelf life of sterilized disposable chopsticks is up to 4 months. Once the shelf life expires, it is likely to bring yellow staphylococcus, Escherichia coli and hepatitis.
