Yes, foodborne illnesses transmitted by bacteria, parasites, and viruses are contagious. Poisoning caused by chemicals and toxins is rarely contagious. Consuming contaminated water and food is the major reason for the rise of food poisoning. Symptoms may vary from person to person. Some common symptoms are vomiting, nausea, indigestion, abdominal cramps, fever, and diarrhea. Some people develop symptoms within an hour or day after consuming the food.
Chemicals and toxins found in food can also lead to food poisoning, but it is not as contagious and severe as the sickness caused by bacteria. Continue reading this blog to find out answers to this question ‘is food poisoning contagious?
More than 250 types of food poisoning have evolved in the world. The following organisms are the major reasons for them.
When you consume contaminated food or water, bacteria leech into the gastrointestinal tract and cause sickness. Salmonella, Shigella, E.Coli, Listeria, Campylobacter jejuni, and Staphylococcus aureus are the bacteria that cause foodborne illness.
The contamination could have happened in different ways such as
Don’t keep the food uncovered for too long, close it with a lid and refrigerate it. Try to avoid if the food has a foul smell.
Viruses can be found in food, or transmitted from person to person. Norovirus, a common foodborne illness may raise the inflammation in stomach and intestines. Hepatitis A is another virus that is more contagious and often leads to liver infection. This virus can be seen in the stool or blood of the infected people. And that is why people are advised to wash their hands after using the restroom. Otherwise, they can spread the virus through handshake or the surfaces they touch like floors, plates, switches, handles, and so on.
Salmonella and Campylobacter can live on the surface for up to four hours, meanwhile, norovirus can live for weeks.
Unlike bacteria, parasites are organisms that develop in different sizes. Some are microscopic while others are large enough to see through the naked eye. They can be found in other organisms, from where they receive the nutrients. Parasites live in the stools of humans and animals.
When you are suffering from food poisoning, make sure you stay home so that you get adequate rest and you don’t spread it to others. Go out only if there is a dire necessity. Keep yourself hydrated by drinking plenty of water.
We cannot say for sure whether a particular case of food poisoning is contagious or not. However, since the microbes causing food poisoning are contagious, you need to assume that your case (if you’re facing it) is contagious, to be on the safer side. It is also extremely important to practice proper hand hygiene. Last but not least, get the advice of your healthcare provider.
Do not include spicy food after recovering from food poisoning. Start with mild and fiber-rich foods to avoid further complications.
Food poisoning is contagious, so anyone can contract it knowingly or unknowingly. Once you sense the symptoms, you need to take preventive measures as soon as possible. Vomiting and diarrhea will cause dehydration, and dizziness, in such cases, the patient should be hospitalized before getting critical. Here are some simple methods to treat and prevent food poisoning.
When you follow the above measures, you can prevent germs causing food poisoning from spreading to others. But as the saying goes, “Prevention is better than cure,” eat food that is properly cooked, store food in refrigerators (if necessary), and avoid eating unhealthy food.
