每日一练，专升本英语阅读理解练习(10.14)

　　Food is sometimes polluted with harmful substances. A person who eats such food may get an illness called food poisoning. Food poisoning is usually not serious but some types are deadly. The symptoms of food poisoning usually begin to appear within hours after people eat the poisoned food. Fever is one of the most common symptoms.

　　Some microorganisms(微生物) can cause food poisoning. After entering the human body, these tiny living things release poisons that make people sick.

　　Some chemicals can also cause food poisoning. They are often added to food while food is being grown, processed or prepared.

　　Some plants and animals contain natural poisons that are harmful to people. These include some seafood, grains, nuts, seeds and mushrooms.

　　When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and warm temperatures. This means people should never touch food with dirty hands or put food on unwashed surfaces. Some food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganism. People should wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural substances that are poisonous to humans. In addition, some types of fish are poisonous.

　　Most people recover from food poisoning after a few days of resting and drinking more water. If people eat natural poisons, they must go to the hospital right away.
