严重食物中毒主要是由食物内细菌生长所产生的毒素或食物内附带有某些毒物而引起的。有些植物是有毒的,除了毒蘑菇有时被采集误认为是可食用的品种外一般食用后危险并不大。食物感染在出现症状前常有一段潜伏期,而食物中毒则出现较快。症状的轻重与所食用特种食物的量有关。更为正确的说是与食入毒素的量有关。 Serious food poisoning is mainly caused by the toxins produced by bacterial growth in foods or the presence of certain toxicants in foods. Some plants are poisonous, except that poisonous mushrooms are not generally considered as dangerous to eat after they are sometimes mistaken for edible varieties. Food infections often have a latent period before symptoms develop, and food poisoning occurs more rapidly. The severity of the symptoms depends on the amount of special food consumed. More correctly, it is related to the amount of toxins ingested.
