Any snakebite can be dangerous if infection (感染) sets in. Some types of snake poison make the bite area swollen (肿胀的) or painful. Others cause bleeding or damage the heart’s nerves. Here are some especially dangerous snakes:

The largest of all poisonous snakes, king cobras can reach 5.5 meters in length. Each king cobra bite contains enough poison to kill an elephant — or 20 people. But these big snakes usually avoid people. They live throughout India, southern China and Southeast Asia.

A bite from Australia’s inland taipan, the world’s most poisonous snake, releases enough poison to kill 100 men. The good news is that people rarely come in contact with this snake, and a treatment for its poison exists.

Russell’s viper lives throughout Asia, including India, southern China, and on the island of Taiwan. It prefers grassy fields but can be found in forests and urban areas. It bites more people and causes more deaths than any other poisonous snake.

Though short, the common Indian krait packs a powerful punch (攻击) in its bite. Most often, it strikes people at night while they are sleeping. Since the bite causes little pain, victims are often not sure that they have been bitten until they begin to experience stomach cramps (痉挛). Without treatment, symptoms will worsen quickly and can lead to death.

The black mamba, a native of Africa, is actually olive or grey in color. Only the inside of its mouth is black. When black mambas feel threatened by a human, they make a loud hissing sound to warn the person away. If the warning is ignored, the snake will attack the person repeatedly. And they can attack quickly, moving over the ground at speeds of up to 20 kilometers per hour.

Some snakes eat other snakes, even poisonous ones. The poison does not do them any harm(伤害). Snakes can swallow(吞下) things that are bigger around than they themselves are. This is possible because the jawbones(腭骨) are loosely joined, and the mouth can stretch（伸展）to make room for a fat animal. The snake’s slim body stretches to make space for the animal when it is inside.

Many snakes eat birds’ eggs or frogs（青蛙）. Others eat pests（害虫）, mice and other animals that harm crops on farms. Because snakes do this valuable work, you should never kill one. It is too dangerous for you to kill a poisonous one. Leave that job to experts.

Food sometimes gets poisoned(中毒) with harmful things. A person who eats such food can get

an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of

the most common symptoms.

Certain microorganisms(微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放) poisons that make people sick.

Some chemicals（化合物） can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.

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

When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also 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 materials that are poisonous to humans. In addition, some types of fish can be poisonous.

Most people recover from food poisoning after a few day of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
