Food poisoning: causes, symptoms and treatment

Food poisoning - Symptoms and treatment | Recetas Medicas

Food poisoning is a form of stomach illness that affects thousands of people every year. Food poisoning often has a rapid course with symptoms such as vomiting, diarrhea and stomach pains. With rest and fluids, the symptoms often go away within a day. Here we go through everything you need to know about food poisoning, common causes, symptoms and what you can do to avoid getting it.

What is food poisoning?

You can get food poisoning if you ingest food or drink that is contaminated with harmful microorganisms such as bacteria (for example salmonella, campylobacter and listeria), viruses, parasites or various poisons, so-called toxins. Food can become contaminated in various ways at all stages of the production chain. You can get sick from food you eat in restaurants, food you buy in the store and food you cook yourself at home. A common cause of food poisoning is food that has not been stored or cooked properly, which gives bacteria a chance to multiply and produce toxins. Even natural toxins found in certain plants and fungi can cause food poisoning if the food is not prepared properly.

Symptoms of food poisoning

The symptoms of food poisoning can vary depending on which microorganism has caused the poisoning, but some of the most common symptoms are:

• Nausea
• Vomiting
• Diarrhea
• Stomach cramps, cramps and stomach pains
• Fever
• Feeling of weakness

Although the symptoms are unpleasant, most cases of food poisoning are mild and resolve on their own without treatment, usually within one to two days.

Incubation period: how fast does food poisoning come?

Symptoms can appear within hours of ingesting the contaminated food, but it can also take days or even weeks for symptoms to appear. How quickly you get sick depends on several factors, including the type of microorganism that caused the poisoning and your general condition. Therefore, it can be difficult to know when and from what you got food poisoning. If you suspect that you have been poisoned by food or drinking water, you should report it to the authority responsible for the control of food and drinking water in your municipality. In this way, you can prevent more people from getting sick.

Stomach upset or food poisoning?

Symptoms such as diarrhea, nausea and vomiting can be caused by many different things. Stomach illness, for example, resembles food poisoning but is usually caused by viruses, especially norovirus and rotavirus. Stomach disease spreads easily between people, usually through direct contact with an infected person or through contaminated surfaces, food or drink. Food poisoning is primarily caused by ingestion of contaminated food.

Is food poisoning contagious?

Food poisoning itself is generally not considered contagious in the sense that it is not transmitted from person to person through direct contact. Food poisoning is caused by consuming food or drink that is contaminated with harmful microorganisms or toxins. When a person suffers from food poisoning, it is the contamination of the food that is the problem, rather than an infection that is transmitted between people.

However, the microorganisms that cause food poisoning, such as certain viruses and bacteria, can be contagious and spread between people in other ways. For example, a person with viral food poisoning, such as norovirus, can spread the virus to others through direct contact or by contaminating food that others then eat. In such cases, it is not the food poisoning as such that infects, but the underlying virus or bacteria. Therefore, it is important to maintain good hygiene even in case of food poisoning.

Should you stay home if you have food poisoning?

It is often wise to stay home if you have food poisoning, for several reasons. First, the body needs rest to recover from the unpleasant symptoms of vomiting, diarrhea, stomach cramps and fever that are common with food poisoning. Resting reduces the risk of complications and helps speed recovery.

Second: although food poisoning itself is not contagious in the same way as a cold or flu, the bacteria or virus that caused the condition can be. If the food poisoning is due to an infectious substance, you can unknowingly spread the infection to others. This is especially important if you move around in environments where you have close contact with other people, such as workplaces, schools and hospitals.

Treatment for food poisoning

Treatment of food poisoning mainly involves relieving symptoms and preventing dehydration. You should stay at home and rest, drink plenty of fluids and, if possible, eat easily digestible food. Good foods to start with after food poisoning can be, for example, toast, banana, white rice or boiled potatoes. You should avoid strong or fatty foods, coffee, nicotine and alcohol until you feel fully recovered.

If symptoms are severe, last more than a few days, or if there are signs of severe dehydration (such as extreme thirst, dry mouth, very dark urine, or little to no urine), you should seek medical attention. Seek emergency care if a child with food poisoning develops a high fever and shows signs of dehydration.

Prevent food poisoning

To reduce the risk of food poisoning, it is important to handle food and maintain hygiene in a safe way:

• Wash your hands thoroughly with warm water and soap before cooking and after handling raw meat, raw fish, and raw chicken.
• Wash knives, cutting boards and other kitchen utensils thoroughly, especially if you have used them to handle raw meat.
• Cook the food properly, please use a thermometer to ensure that the food has reached the right temperature.
• Cool down the food quickly after eating and store it in the refrigerator.
• Thaw frozen food in the refrigerator and not at room temperature.
• Wash fruits and vegetables thoroughly.
