Youโve just come back home after eating at a local restaurant.ย Suddenly, youโre feeling pain and discomfort in your abdomen. You may have contracted food poisoning, an all too common occurrence.ย According to Statistics Canada, itโs estimated eight million Canadians are affected by food poisoning each year. Out of these over, 11,000 will require hospitalization, and more than 200 people will die.ย
Food poisoning can be severe. However, a majority of cases will resolve on their own. When purchasing groceries from a store or eating out, food poisoning isnโt something you should worry about. Learn more about what food poisoning is, its signs and symptoms, as well as steps you can take to prevent it. Find out about your legal rights. In some cases, you may even be able to claim compensation.ย
What Is Food Poisoning?ย
Food poisoning is an illness caused by consuming food that has been contaminated. Bacteria, viruses, or even fungi can contaminate food. It can occur in several ways. Itโs possible you ate undercooked meat. Food can also be spoiled if it was stored improperly or past its best before date.ย
Several cases of produce, such as lettuce, have been contaminated with E. coli. Finally, food poisoning may happen from contaminated water as well. The Walkerton crisis highlighted this issue for all Canadians. The Public Health Agency of Canada has identified five primary organisms responsible for food poisoning in Canada.

Of all of these, Listeria tends to be the most serious and causes the most deaths. Many of these bacteria produce toxins, which is one of the main reasons for the sickness. While the cooking process can kill the bacteria, the toxins can still make you ill. If any food looks spoiled, you should simply throw it out.
Symptoms of Food Poisoning & Duration
Food poisoning symptoms can vary from person to person. Different bacteria can also produce various kinds of illnesses. Generally, people may have some combination of the following:
- Diarrhea
- Nauseaย
- Vomiting
- Abdominal pain
- Fever
- Muscle aches
Food poisoning signs and symptoms can range from mild to severe. Many people have likely experienced mild food poisoning after eating something that didnโt agree with them. In the case of severe symptoms, it may be time to contact your doctor. Sometimes food poisoning could be mistaken for the stomach flu as many symptoms overlap.
A common question is how long food poisoning lasts. Typically, symptoms will start after six to 24 hours but may come even earlier. Most cases will resolve themselves within one to two days. If your symptoms persist, itโs a good idea to see a doctor.
Treatment for Food Poisoning
One of the main concerns with food poisoning is dehydration, so itโs crucial to drink fluids. Opt for drinks that contain electrolytes (such as sports drinks) rather than relying on water only. This is because water alone is low in sodium and potassium, lost during diarrhea and vomiting. There are usually no specific treatments other than rest and avoiding any different foods, which may be aggravating.ย
For people requiring hospitalization, they may receive fluids by IV. Antibiotics may be helpful in only some cases. This is because the cause of food poisoning can often be a virus. From the chart above, Norovirus causes more cases than the four bacteria combined.
