How long is the shelf life of disposable chopsticks?

According to experts, disposable chopsticks will breed all kinds of molds for a long time. If moldy disposable chopsticks are used for a long time, light ones may lead to infectious diarrhea, vomiting and other digestive system diseases. Severely moldy chopsticks will reproduce "aflatoxin", which has been widely determined to induce disease. It is reported that when the temperature is 100C ~ 350C and the humidity reaches 15%, the mold on the moldy bamboo stick can grow exponentially. At present, more than 200 kinds of molds have been found, and aflatoxin is one of them. In the same amount, its toxicity is 10 times that of potassium cyanide, which is a highly toxic chemical. It is more toxic than the venom of Cobra and golden ring snake. Its carcinogenic effect is 7.5 times stronger than dimethylnitroamine and 900 times stronger than the pathogenic compound "cream yellow".
When eating noodles, many citizens like to scald their chopsticks in the noodle soup, thinking that they can play a complete role in selling bacteria. In fact, the role of selling bacteria in this way is very limited. Only when chopsticks are boiled in boiling water at 100 ℃ for more than 5 minutes, can they achieve the ideal effect of bacteria elimination. The more ideal way of bacteria elimination is to use high-temperature disinfection cabinet.
In addition, compared with disposable chopsticks, household chopsticks are simpler to transform. Because household chopsticks are used frequently and washed with water for a long time, the water content of chopsticks is particularly high, which simply becomes a hotbed for bacterial growth. Such as Staphylococcus aureus, Escherichia coli, etc. Putting chopsticks in the cabinet for a long time may increase the probability of chopsticks metamorphosis by more than five times. Generally speaking, chopsticks should be updated after half a year.
