Food Poisoning and Safe Food Handling
Is this topic for you?
What is food poisoning?
Food poisoning is an illness caused by eating foods that have harmful organisms in them. These harmful germs can include bacteria, parasites, and viruses. They are mostly found in raw meat, chicken, fish, and eggs, but they can spread to any type of food. They can also grow on food that is left out on counters or outdoors or is stored too long before you eat it. Sometimes food poisoning happens when people don't wash their hands before they touch food.
Most of the time, food poisoning is mild and goes away after a few days. All you can do is wait for your body to get rid of the germ that is causing the illness. But some types of food poisoning may be more serious, and you may need to see a doctor.
What are the symptoms?
The first symptom of food poisoning is usually diarrhea. You may also feel sick to your stomach, vomit, or have stomach cramps. Some food poisoning can cause a high fever and blood in your stool. How you feel when you have food poisoning mostly depends on how healthy you are and what germ is making you sick.
If you vomit or have diarrhea a lot, you can get dehydrated. Dehydration means that your body has lost too much fluid.
How do harmful germs get into food?
Germs can get into food when:
How will you know if you have food poisoning?
Because most food poisoning is mild and goes away after a few days, most people don't go to the doctor. You can usually assume that you have food poisoning if other people who ate the same food also got sick.
If you think you have food poisoning, call your local health department to report it. This could help keep others from getting sick.
Call your doctor if you think you may have a serious illness. You may need to see your doctor if your diarrhea or vomiting is very bad or if you don't start to get better after a few days.
If you do go to the doctor, he or she will ask you about your symptoms (diarrhea, feeling sick to your stomach, or throwing up), ask about your health in general, and do a physical exam. Your doctor will ask about where you have been eating and whether anyone who ate the same foods is also sick. Sometimes the doctor will take stool or blood samples and have them tested.
How is it treated?
In most cases, food poisoning goes away on its own in 2 to 3 days. All you need to do is rest and get plenty of fluids to prevent dehydration from diarrhea. Drink a cup of water or rehydration drink (such as Pedialyte) each time you have a large, loose stool. Soda and fruit juices have too much sugar and shouldn't be used to rehydrate. Doctors recommend trying to eat normally as soon as possible. When you can eat without vomiting, try to eat the kind of foods you usually do. But try to stay away from foods that are high in fat or sugar.
Antibiotics usually aren't used to treat food poisoning. Medicines that stop diarrhea (antidiarrheals) can be helpful, but they should not be given to infants or young children. You shouldn't take antidiarrheals if you have a high fever or have blood in the diarrhea, because they can make your illness worse.
If you think you are severely dehydrated, you may need to go to the hospital.
