Mothballs usually can not be put together with food, because mothballs will volatilize toxic gas, which can easily pollute food. Although mothballs have some insect repellent effect, it is still recommended to reduce the use of mothballs in daily life, which can avoid the invasion of harmful substances into human body to a certain extent. Mothballs are mainly used to prevent insects and kill insects, mostly placed in the closet. If mothballs and food are put together, because the common mothballs in the market contain toxic substances such as dichlorobenzene, such substances may contaminate food, which may lead to poisoning after eating food, causing dizziness, headache, diarrhea, vomiting and other symptoms in human body. If you eat food put together with mothballs for a long time because you do not show any bad situation after eating, it may also cause some harm to your health. If food and mothballs are found to be stored together, it is recommended to discard these foods in time so that they will not be detrimental to health after being eaten by mistake. If you feel uncomfortable after eating food put together with mothballs, it is recommended to go to the regular hospital in time to seek medical advice and treatment by doctors.
